MANUAL SPECIAL NOTATIONS
In the Alstom manuals, there are three methods used to convey special informational
notations to the reader. These notations are warnings, cautions, and notes. Both
warnings and cautions are readily noticeable by boldface type two lines beneath the
caption.
Warning
A warning is the most important notation to heed. A warning is used to tell the reader
that special attention needs to be paid to the message because if the instructions or
advice is not followed when working on the equipment then the result could be either
serious harm or death. The sudden, unexpected operation of a switch machine, for
example, or the technician contacting the third rail could lead to personal injury or death.
An example of a typical warning notice follows:
WARNING
DISCONNECT MOTOR ENERGY WHENEVER WORKING ON SWITCH
LAYOUT OR SWITCH MACHINE. UNEXPECTED OPERATION OF
MACHINE COULD CAUSE INJURY FROM OPEN GEARS, ELECTRICAL
SHOCK, OR MOVING SWITCH POINTS.
Caution
A caution statement is used when an operating or maintenance procedure, practice,
condition, or statement, which if not strictly adhered to, could result in damage to or
destruction of equipment. A typical caution found in a manual is as follows:
CAUTION
Turn power off before attempting to remove or insert circuit boards into a
module. Boards can be damaged if power is not turned off.
Note
A note is normally used to provide minor additional information to the reader to explain
the reason for a given step in a test procedure or to just provide a background detail. An
example of the use of a note follows:
NOTE
A capacitor may be mounted on the circuit board with a RTV adhesive.
Use the same color RTV.

1.1.
SCOPE OF MANUAL
This manual contains information that explains the operation and maintenance of the
Alstom Model 6 Electric Switch Machine (Part Number [P/N] 52500-004-XX).
1.2.
GENERAL
The Alstom Model 6 switch machine is designed specifically for flat- or gravity- type yard
applications and can be used in car classification yards, receiving and departure yards,
rapid transit yards and industrial spurs.
•
Unique dynamic snubbing feature eliminates mechanical shock by bringing the
machine to a rest at the end of the stroke.
•
An exclusive trailing mechanism is constructed so the switch can be trailed without
damage to the machine, switch points, or fittings.
•
The Model 6 has adequate power for throwing switches of large rail.
•
It is furnished for operation at regular or high speed:
− The regular speed machine has a gear ratio of 79.5 to 1 with an operating time of
1.50 seconds.
− The high speed machine has a gear ratio of 31.8 to 1 with an operating time of
0.6 seconds.
•
It is available with 110 VDC operation or 110 VAC operation.
•
The 110 VAC version includes resistors that provide internal snubbing.
•
The 110 VDC Model 6 switch machine can be equipped with an optional transformer
kit 52506-003-00 for use with a 110 VAC clearance track circuit.
The Model 6 is connected mechanically to switch points and electronically to switch
circuits. The switch machine may be used in conjunction with the Model 7J Switch
Circuit Controller. Safe operation of a switch machine depends largely upon the
condition of the switch layout. A top view of a typical switch layout, with circuit controller
is shown in Figure 1–1.

General Description
1.3.1.
Safety at Switch Machines
1. Keep fingers, feet, tools and equipment out of switch points. Closing points can trap
and crush hands and feet or damage tools and equipment. A wedge properly
inserted between points will prevent an inadvertently energized switch machine from
causing personal injury or equipment damage.
WARNING
ALWAYS BE PREPARED FOR IMMEDIATE SWITCH MOVEMENT.
FAILURE TO DO SO COULD CAUSE YOU TO BE INJURED BY
UNEXPECTED OPERATION.
2. Never step on switch rods. Rod movement can cause serious foot injury or loss of
balance.
3. Because the switch machine is often activated from a remote station (a train control
room), be sure to notify a station that maintainers are working on or around a given
switch machine. This notification may possibly prevent the equipment from being
activated during the reported service.
When the hand crank is inserted, the motor is electrically cut off and the machine
cannot be activated. Insert a hardwood wedge into an open switch point (the gap that is
formed between the through and alternate track) to prevent the point from closing. Use
these features as protection, but never leave a hand crank inserted in a switch machine
or wedge in the switch points when a train is approaching and the switch must be
thrown.

Theory of Operation
2. SECTION 2 – THEORY OF OPERATION
2.1.
GENERAL
The Alstom Model 6 switch machine is designed for use in flat or gravity-type
classification yards and industrial spurs, and is reliable under all weather conditions.
2.2.
OPERATION
There is no established rule to cover proper operation of the Model 6 without analyzing
the particular circuit involved.
Typically, normal and reverse switch point position is controlled electronically by a
control system and electromechanically performed by a switch machine with or without
with a switch circuit controller (see Figure 1–1 for a configuration including an optional
Model 7J switch circuit controller).
Manual operation is performed with a hand crank.
P1383, Rev. Apr/08

Alstom Signaling Inc.
Theory of Operation
2.2.1.
Manual Operation
The switch machine is manually operated with a hand crank. This operation is
performed by inserting a hand crank into the hand crank access port, located on top of
the switch machine cover. Then turn the hand crank in the direction of desired switch
point movement, see Figure 2–1. Inserting the hand crank activates the crank cut-out
switch assembly and inhibits power operation of the machine. To restore power
operation, a bracket inside the switch machine cover must be pushed back over the
crank access port after the hand crank has been removed.

Figure 2–1. Hand Crank Operation
CAUTION
An excessively bent or worn hand crank can permit closure of the cut-out
switch contacts, allowing motor operation while the crank is inserted.
CAUTION
Do not leave a hand crank inserted in an unattended switch machine. A
switch machine is unable to perform a power operation when a hand crank
is inserted.
P1383, Rev. Apr/08
2–2
Alstom Signaling Inc.
Theory of Operation
2.2.2.
Electrical Operation
When a switch call is performed, the energy circuit to the switch machine motor is
completed allowing the motor to drive the gear train. The motor driven gear train, along
with the main gear roller, moves the cam of the sector assembly. Heavy springs press
the cam roller into the center sector detent, holding the sector and cam in position, as
shown in Figure 2–2. The throw bar, along with the throw bar roller, is moved by the
sector.

Theory of Operation
2.2.2.1.
Obstructed Switch Points
When the switch machine is operated against obstructed switch points, the cam roller is
forced from its normal resting position in the center detent of the sector. This allows the
motor to complete normal rotation of the main gear and shut off without stalling. The
point detection contacts remain open with the switch points against the obstruction.
Obstructions larger than two inches may force the roller entirely out of the center detent
and into the normal or reverse detent, causing the switch points to be positively returned
to their original position. In this condition, the motor operated correspondence contacts
(described under "Types of Contacts") are in correspondence with the call. Since the
point detection contacts are out of correspondence, no indication can result.
The next power operation of the machine causes the cam and sector to return to their
normal relationship.
2.2.3.
Motor
The motor is a four-pole commutator type, equipped with ball bearings. Operating
voltage is 110 VDC. The motor commutator and brushes should not be disturbed unless
it is necessary.
2.2.4.
Clutch
Some regular speed and high speed machines have a friction clutch that does not slip
during normal operation. This clutch is located near the motor end of the machine in the
space above the bushing, see Figure 2–3.

Types of Contacts
There are three types of contacts as shown in Figure 2–4:
1. Motor-Control Contacts:
The motor-control contacts, located in spaces 1A, 2A, 3A, 4A, 5B, 6B, 7B, and 8B, are
operated by two cams on the outside of the main gear. Contact blocks are made
adjustable by means of elongated holes in each end. Proper block locations depend
upon the adjustment of the point detection contact, and, in any case, the motor-control
contacts must not be so close as to make it possible to draw an arc from one side to the
other.
2. Correspondence Contacts:
The correspondence contacts, located in spaces 5A, 6A, 3B, and 4B, are operated by
two cams on the outside of the main gear. These contacts indicate when the main gear
reaches its full stroke position, either normal or reverse.
3. Point-Detection Contacts:
The point-detection contacts, located in spaces 7A, 8A, 1B, and 2B, are operated by a
three-position cam on the sector. The contacts indicate when the throw bar is in its full
stroke position, either normal or reverse.
Point-detection contact 2B is connected in series with correspondence contact 6A-3B to
ensure that the position of the main gear is in correspondence with the position of the
throw bar (to the "B" or left side of the machine) before an indication is given. Contact
7A is connected in series with correspondence contact 5A-4B to ensure that the position
of the main gear is in correspondence with the position of the throw bar (to the "A" or
right side of the machine) before an indication is given.

Dynamic Snubbing
At the completion of each stroke, the overrun of the motor generates a dynamic current.
This current flows through a low resistance circuit that includes the motor field and
armature, control relay contacts, and either the RW or NW wire and the CW wire. (R
equals reverse, N equals normal, and C equals common.) The dynamic snub current
generated quickly slows and stops armature rotation.
As shown in Figure 2–5, when energy is applied to the RW and CW wires, pointdetection contacts1B and 2B open as a result of the throw bar moving approximately
1/4 inch. When the throw bar completes its stroke, (to the right) the point-detection
contacts 7A and 8A close. When this occurs,
•
motor control contacts 7B-8B, 6B-5B, and correspondence contacts 6A-3B open
•
motor control contacts 1A-2A, 3A-4A, and correspondence contact 5A-4B close
This action opens the motor power circuit and closes the dynamic snub circuit (the
dynamic snub circuit is through the NW to CW wires).
When the machine is operated to the opposite position (to the left), the same action
occurs as described previously, except that energy is applied to the NW and CW wires
and the dynamic snub circuit is through the RW and CW wires.

Resistor Heaters
For cold weather operation, heaters are available for installation in the motor and
contact compartments. The wiring diagram, Figure 2–5, shows these heaters installed
connected to 110 volts.
2.2.6.
Trailable Feature
A switch machine can be “trailed” by manually forcing the track switch points to their
opposite position. This is achieved by running a train over incorrectly positioned switch
points.
The toggle-type sector assembly permits a switch to be trailed without damage to
internal switch machine components, switch points, fittings and connecting rods. When
a switch is trailed, a force is applied to the sector by the throw bar and the throw bar
roller. This force overcomes the spring force holding the cam roller into the sector detent
causing the cam roller to come out of the sector detent. The cam roller movement
permits the sector to change its position with respect to the cam, see
Figure 2–6.

The motor, however, is not energized. The sector and throw bar follow the switch points
in the position to which they are trailed. In this condition, the motor-operated
correspondence contacts (described under "Types of Contacts") remain in
correspondence and no indication can result.
P1383, Rev. Apr/08
2–8
Alstom Signaling Inc.
Theory of Operation
A trailed machine must be reset. To reset a switch, it must be trailed again (restoring the
switch points to their original position) or called to the trailed position. The next power
operation of the machine causes the cam and sector to return to their normal
relationship. It is normal for the machine to make a loud noise when the roller returns to
its detent in the sector.
Proper operation of the trailable feature can be verified by operating the switch machine
against an obstruction larger than 2 inches.

3. SECTION – INSTALLATION
3.1.
GENERAL
Model 6 Switch Machines should be installed in accordance with the property’s
approved switch layout. A newly installed machine should be adjusted and lubricated
according to the criteria in this manual. Refer to Appendix A for example switch machine
layouts with a switch circuit controller included as part of the installation.
Satisfactory operation of the switch machine depends on it being installed properly,
adjustments made correctly, all parts lubricated according to the lubrication chart, and
maintenance performed at designated intervals. This section describes the installation
and initial adjustments of the switch machine.
3.2.
PROPERTY’S REQUIREMENTS
Although this publication gives set-up information on a typical machine installation, the
maintainer should always be sure the switch layout is done in accordance with the
requirements of the rail property.
3.3.
INSTALLATION
The installation process consists of three elements: physical mounting of the equipment
by the tracks, making necessary adjustments and electrical connections, and testing for
proper mechanical movement. Details of this process are described next.
When following the procedures in this manual, the following warnings must be heeded:
WARNING
WHEN USING THE HAND CRANK ON THIS SWITCH MACHINE, KEEP
A FIRM HOLD ONTO THE HAND CRANK. IF THERE IS SPRING
TENSION IN THE SWITCH POINTS WHEN THE MACHINE BECOMES
UNLOCKED, THE HAND CRANK WILL ACCELERATE RAPIDLY IN THE
DIRECTION IT IS BEING TURNED. IF NOT CAUTIOUS, INJURY BY
THE CRANK’S SUDDEN MOVEMENT COULD RESULT.
WARNING
DISCONNECT MOTOR ENERGY WHENEVER WORKING ON THE
SWITCH LAYOUT OR SWITCH MACHINE. UNEXPECTED OPERATION
OF THE MACHINE COULD CAUSE INJURY FROM OPEN GEAR,
ELECTRICAL SHOCK, OR MOVING SWITCH POINTS.
P1383, Rev. Apr/08
3–1
Alstom Signaling Inc
Installation
3.3.1.
Mounting to Ties
The switch machine location should be well drained to avoid water accumulation in and
around the machine and switch points. Ties throughout the switch layout should be
reasonably straight and properly framed. These ties should be kept well tamped over
their entire length to withstand vibration and strain from passing cars. Switch points
require especially well tamped ties.
Tie plates and parts, which secure the machine to the ties, should be installed and
maintained so that there is no movement of the machine with respect to the rails. The
gage of the switch points must be maintained to the specific dimension for proper
trailing of the machine.
It is essential that the switch points move without excessive drag or spring. Angle bars,
at the heels of the point rails, should be open slightly to provide free operation of the
points. These bars can either be bent, or suitable ferrules can be used in the bolt holes
of the point rails to give the proper opening. Spring in the points results from the heel of
the point striking the stock rail before the points. To eliminate this spring, the stock rails
should be so bent that the points fit properly.
When adjusting the switch points, the points should not be held so tightly against the
stock rails as to cause excessive pressure on the switch machine parts. All rail stops
should be adjusted to bear firmly against the stock rail when the switch is either in the
full normal or the full reverse position.
3.3.1.1.
Right-Hand and Left-Hand Switch Layouts
The differences between the right-hand and left-hand Model 6 switch machine layouts
are in the contact arrangements and throw bar coupling connection. By switching the
NW and RW power at the contact group, the near point closed is maintained as normal
position.
By switching each wiring terminal on the contact group to the opposite terminal for that
same contact, the correspondence for that switch is maintained as the switch layout
moves from the left to the right.
P1383, Rev. Apr/08
3–2
Alstom Signaling Inc
Installation
3.3.2.
Wiring of Machine
Switch machines shipped from the factory have the motor, switch heaters, and crank
contact completely wired. In the field, external wires for switch motor control,
correspondence, and point detection, are brought into the machine through an entrance
coupling. These wires are connected to the appropriate terminals of the contact group
and TB, as shown in the example Switch Layout Circuits of Appendix A.
The power wires must be of adequate size to carry the maximum operating current. For
DC Model 6 Switch Machines the power wires shall have a minimum resistance of 0.5
ohm. The maximum resistance for a high speed DC machine is 2.5 ohms and for a
regular speed DC machine is 5.0 ohms when operating from 60 lead cells or equivalent.
Optimum line resistance for a DC machine is determined by observing the machine in
operation; it should snub smoothly to a stop without striking a mechanical stop at the
end of its stroke. If violent snubbing occurs, resistance must be increased. If the main
gear or sector strikes the stop with considerable force, resistance must be decreased.
In the AC Model 6 Switch machine the snub resistors are provided with the switch
machine inside the AC controller. There is no need to adjust snub resistance in the AC
Model 6 Switch machine.
CAUTION
Do not operate the Model 6 without adequate dynamic snubbing. Damage
may occur to the switch machine gear train components. Typical 110 VDC
control circuits are shown in Figures 3–1 and Appendix A. For 110 VAC
control circuits contact Customer Service at 1-800-717-4477.

Clearance Track Circuit
The 110 VDC Model 6 switch machine can be equipped with transformer group 52506003-00 for use with a 110 VAC clearance track circuit. The components for this option
are located at the opposite motor end of the machine. (This is where the 110 VAC
components would be located in a 110 VAC machine).
A typical transformer group includes one Type K 1/2 transformer, two Type S2
transformers, two adjustable resistors and 16 terminal posts. The wiring diagram of the
110 VDC Model 6, with this transformer group installed, is shown in Figure 3–2.
If the transformer group is to be added to the machine in the field, the four-post terminal
block in the contact compartment is removed, the transformer group is installed, and the
electrical connections are made according to the wiring diagram, Figure 3–2.

Connection and Initial Adjustment
After the switch machine is mounted, the following procedure should be performed to
connect and initially adjust the equipment. When performing this procedure, check that
switch points are not held so tightly against the stock rails as to cause excessive
pressure on switch machine parts (excessive point pressure as defined by the
customer/authority.). All rail stops should be adjusted to bear firmly against the stock rail
when the switch is either in the full normal or the full reverse position. Perform the
following procedure after a switch machine has been installed or when a switch machine
needs to be connected to the rails.

The throw-bar stroke is 5-1/2 inches maximum. The throw of the switch at the
switch adjustment bracket must be less than 5-1/2 inches to allow for lost
motion on either side of the bracket, any linkage, and any motion relative to
the stock rails.
Verify that switch points are not held so tightly against the stock rails as to
cause cam roller to move in the detent in sector. If the roller tends to move out
of the detent, it prevents the throw bar and sector from making a full stroke
and affects the operation of point-detection contacts. This is an indication that
excessive pressure is present between the switch points and stock rails.

Dynamic Snubbing Resistance Check
When the Model 6 switch machine is first installed and when motor control contacts are
replaced, perform a dynamic snubbing resistance check. For DC switch machines follow
the procedure in Table 3–6 to check resistance. For AC switch machines follow the
procedure in Table 3–7 to check resistance.
For DC operated switch machines the power wires must be of adequate size to carry
the maximum operating current and have a minimum resistance of 0.5 ohm. The
maximum resistance for a high speed machine is 2.5 ohms and for a regular speed
machine is 5.0 ohms when operating from 60 lead cells or equivalent.
For AC operated switch machines the power wires must be sized to carry the maximum
operating current and minimize voltage loss at the switch machine. There is no
minimum resistance requirement because the snub resistors are inside the AC
controller located inside the switch machine.
CAUTION
Do not operate the Model 6 without adequate dynamic snubbing. Damage
may occur to the switch machine gear train components. Typical 110 VDC
control circuits are shown in Figures 3–1 and Appendix A. For 110 VAC
circuits contact Customer Service at 1-800-717-4477.

•
For a high speed machine adjust resistance to 2 to 2.5 ohms.
•
For a regular speed machine adjust resistance to 4.5 to 5 ohms.

4
Operate the switch machine electrically to end of stroke. The switch machine
must snub smoothly at end of stroke and must not hard stop: the operating
roller on the main gear shaft must not strike the stop in the center of the
operating cam. Repeat for the opposite direction.
If the machine hard stops, decrease the snub resistance and repeat operation
of the switch machine. Decrease resistance until the machine no longer hard
stops in either direction.
5
Insert the hand crank and count the number of turns it takes to reach end of
stroke.
For a high speed machine the number of turns is 0.75 maximum.
For a low speed machine the number of turns is 2.25 maximum.
6
Remove the hand crank and operate the switch machine electrically to end of
stroke in opposite direction. Repeat Step 4 for the opposite direction, then
continue to Step 7.
7
If the switch machine snubs smoothly and it takes the recommended number
of hand crank turns to reach end of stroke, then continue to Step 8.
If the machine snubs violently or it takes more than the recommended number
of hand crank turns, then increase snub resistance and repeat Steps 4
through 7.
• For 110 VDC machines insert a line resistor in series with the CW wire to
reduce snubbing.
8
If the machine still does not snub smoothly or if the number of crank turns at
end of stroke is more than the maximum listed in Step 5:
• Verify the condition of the motor control contacts, clean or adjust as
required.
•
Verify condition of motor commutator and motor brush contact. See Table

replace the resistor assembly (all four resistors).
4
Operate the switch machine electrically to end of stroke in both directions and
verify the following:
A. The switch machine must snub smoothly (not violently) at end of stroke.
B. At the end of stroke the machine must not hard stop: the operating roller on
the main gear must not strike the stop in the center of the operating cam.
C. Insert the hand crank and count the number of turns it takes to reach the
end of stroke:
• For a high speed machine the number of turns is 0.75 maximum.
•
For a low speed machine the number of turns is 2.25 maximum.
If the machine satisfies A, B, and C above, this procedure is complete.
Otherwise, continue to Step 5.

Lubrication
All Model 6 switch machines should be systematically lubricated at least bimonthly; see
the lubrication chart, Table 4–4. The frequency of lubrication should depend upon the
frequency of operation and, to some degree, upon weather and other local conditions.
Observation of the condition of working parts determines the need for more or less
frequent application.
Lubricate the gear faces and all internal unpainted parts, including the throw bar, with a
light grease or medium oil. A preferred lubricant is an all temperature, lithium-based,
extreme pressure grease that has a temperature range suitable for the location of the
switch machine. See Figure 4–1 for an illustration identifying the lubrication locations.
The motor contains lifetime lubricated ball bearings. If the switch machine has become
flooded, it must be cleaned, dried, and lubricated to prevent further damage to its
internal parts. Flood water may contaminate the lubricant in the bearings. A flooded
machine should be disassembled and its bearings cleaned, examined, and lubricated if
not corroded, damaged or worn.

6. SECTION 6 – CORRECTIVE MAINTENANCE
6.1.
GENERAL
Corrective maintenance is the act of restoring malfunctioning equipment to an operable
condition. Maintenance personnel should read and follow all WARNING statements to
avoid injury to themselves or damage to the equipment.
Corrective maintenance consists primarily of component replacement.
See Heading 4.2.1., Special Tools and Test Equipment, for a list of tools used in all
Model 6 Switch Machine maintenance, including corrective maintenance.
6.2.
OPERATING FROM PANEL CONTROL
The Model 6 Switch Machine has no mid-stroke restoration feature. If the switch
machine is cranked out of position, resetting the crank motor cut-out contacts does not
allow the machine to power over to its original position. The Control Panel operator has
to throw the switch to the opposite position by using the individual switch control lever
provided on Control Panel. In addition, operating a switch machine by these levers
prevents the switch machine from returning to its original position after the switch has
been called to the opposite position, then called back to the original position before the
switch completes its stroke. Consequently, the switch machine shows out of
correspondence, and it must to be called back to the opposite position.
