Chicago South Shore and South Bend Railroad (NICTD)



NICTD Signal Aspects for Control Point 32.2

The signals at CP 32.2 were reconfigured in 2011 to the layout shown below.

WESTBOUND

CP 32.2 Westbound - Trains Arriving at Carroll Ave Station (from South Bend)
Proceed
One of the first three sets of indications are seen when the dispatcher has cleared a train to proceed westbound into the Carroll Ave Station.

CLEAR then CLEAR
The track ahead is clear and CP 33.0 is not restricting or approach.
ADVANCE APPROACH then APPROACH
The track ahead is clear and the train may proceed prepared to stop at CP 33.0 (School St).

This indication would be seen if a train from South Bend has been cleared to follow a train that is currently between CP 33.0 and CP 34.5 (Amtrak).
CLEAR then ADVANCE APPROACH is seen if CP 33.0 is approach. (CP 33.0 cleared WB; No train between CP 32.2 and CP 34.5; and signal CP 34.5 restricting or stop.)
RESTRICTING
The train has permission to proceed past the signal at a reduced speed.

The diamond signal is at the normal stopping point for a westbound train making a passenger stop. The first four cars of a train can load or unload passengers when stopped at the diamond. The train must move beyond the diamond to make a reverse move into the yard. Restricting is seen at the first signal if the dispatcher has cleared the train to enter the station but has not cleared the train to cross the diamond or the track ahead is not clear.
Do Not Proceed
STOP
The stop indication is shown when the dispatcher has not cleared the train to proceed. The train must stop and stay stopped until it receives permission from the dispatcher to proceed.

This indication is seen when an arriving westbound train is held for an eastbound train. This replaces the practice of verbally allowing a train to proceed past Karwick Rd to this point.
Proceed to South Harbor
RESTRICTING
The restricting indication (bottom light flashing) is shown when the dispatcher has cleared the train to proceed to South Harbor freight yard.

The main line switch is remote controlled, however the derail and switches on the CSS freight line must be thrown by hand.

CP 32.2 Westbound - Trains Leaving Carroll Ave Yard
The signal shown is on the yard lead. The signal on CY-0 (the center car yard track) follows a similar pattern of operation.
Proceed
One of the first three sets of indications are seen when the dispatcher has cleared a train to proceed westbound into the Carroll Ave Station.

CLEAR then CLEAR
The track ahead is clear and CP 33.0 is not restricting or approach.
ADVANCE APPROACH then APPROACH
The track ahead is clear and the train may proceed prepared to stop at CP 33.0 (School St).

This indication would be seen if a train from the yard has been cleared to follow a train that is currently between CP 33.0 and CP 34.5 (Amtrak).
CLEAR then ADVANCE APPROACH is seen if CP 33.0 is approach. (CP 33.0 cleared WB; No train between CP 32.2 and CP 34.5; and signal CP 34.5 restricting or stop.)
RESTRICTING
The train has permission to proceed past the signal at a reduced speed.

The diamond signal is at the normal stopping point for a westbound train making a passenger stop. The first four cars of a train can load or unload passengers when stopped at the diamond. The train must move beyond the diamond to make a reverse move toward South Bend.
Do Not Proceed
STOP
The stop indication is shown when the dispatcher has not cleared the train to proceed. The train must stop and stay stopped until it receives permission from the dispatcher to proceed.

This indication is seen when a departing westbound train is held for an eastbound train. This replaces the practice of verbally clearing a train to leave the yard.
Proceed to South Harbor
RESTRICTING
The train has permission to proceed past the signal into the RIP tracks (repair in place) or the South Harbor freight yard.

Trains leaving the yard for South Harbor on the "New Connection" or via the main line connection will see this indication. Note: The interlocking switches are remote controlled, however the derail and switches on the CSS freight line must be thrown by hand.

CP 32.2 Westbound - Trains Leaving Carroll Ave Station (Diamond Signal)

One of the following indications are seen on the westbound diamond signal when the dispatcher has cleared a train to cross the diamond and proceed westbound toward Chicago. The aspect displayed depends on track occupancy and the aspect of the next signal (CP 33.0).

CLEAR: The track ahead is clear and next signal is not restricting or approach.

ADVANCE APPROACH: The track ahead is clear, but the next signal is approach.

APPROACH: The track ahead is clear, but the next signal is restricting or stop.

RESTRICTING: The track ahead is not clear, however the train has permission to proceed past the signal at a reduced speed.

STOP: The stop indication is shown when the dispatcher has not cleared the train to proceed. The train must stop and stay stopped until it receives permission from the dispatcher.

EASTBOUND

CP 32.2 Eastbound - Trains Arriving at Carroll Ave Station from the West
(See below for eastbound trains terminating in Michigan City.)
Proceed toward South Bend
One of the first three sets of indications is seen when the dispatcher has cleared a train to cross the diamond and proceed eastbound into the Carroll Ave Station, then on to South Bend.
These indications would only be seen by trains passing through toward South Bend.

CLEAR then CLEAR
The track ahead is clear and next signal is not restricting or approach.
CLEAR then ADVANCE APPROACH
The track ahead is clear however CP 31.3 is "Approach".
ADVANCE APPROACH then APPROACH
The track ahead is clear and the train may proceed prepared to stop at CP 31.3.
Do Not Proceed
STOP
The stop indication is shown when the dispatcher has not cleared the train to proceed. The train must stop and stay stopped until it receives permission from the dispatcher to proceed.

CP 32.2 Eastbound - RESTRICTING Signal
The train has permission to proceed past the signal at a reduced speed. There are four scenarios that apply:
Proceed toward South Bend - Main Line Obstructed
The track is cleared through both signals to use the main toward South Bend, however the next track segment is occupied or has a defect (open switch or broken rail).
Proceed into Yard - Train Terminating at Shops
The track is cleared through both signals to enter the yard.

Note: Hand operated switches and derails beyond the interlocking must be manually thrown.
Proceed to Platform - Platform Signal Not Cleared
The track is cleared through the first signal but the second signal is not clear.

If the signal at the platform is stop the train must stop before that signal. The location of the next signal does not allow any cars to stop at the platform. If the signal at the platform is restricting (above) then the train can pull past the signal to the normal stopping point for passenger trains and/or continue under the rules for a restricting signal.
Proceed to CSS Kingsbury Line
The track is cleared to the CSS Kingsbury Line.

Note: Hand operated switches and derails beyond the interlocking must be manually thrown.
The defined meaning of the signals on all above charts is as shown in the Chicago Operating Rules Association guide (CORA), 6th Edition, dated October 1, 2007. Additional notes have been added to increase understanding. Signal configuration is by personal observation.

NICTD uses approach lit signals on the CTC controlled section of their mainline. Siding signals such as the freight track dwarf signals are constantly lit.
