AI traffic on Lehigh & Hudson River 4 Options

[AT RR]

Hi everyone,
I have been trying to run this route but have been running into a stand off situation with the AI traffic and have yet been able to finish a work order.

The AI traffic is a great add on to the route but the problem I am seeing is the route has signals at interlocking and passing sidings but it also has block signals along long single track areas.

These single track block signals is the area where I get the stand off situations.

The question is: is there a way to change the AI path so the trains only stop at interlocking and passing sidings? Or can the signal file be modified so the AI trains do not look at the block signal as an interlocking signal?

I know I can run the route without AI traffic but this makes for a very barren railroad.

I'm asking these questions as all of the templates I developed for the Jersey City route did not have AI traffic so I don't know the first thing about this subject.

Peter,

Here is an excerpt from one of the docs included with the 1940 version of the route:

SPECIAL INSTRUCTIONS

Speed signs are located on the right of track and indicate maximum speed in mile per hour.

YARD LIMITS

Indicated by Yard Limit boards at the following points:

Maybrook
Warwick
Franklin
Sparta Jct.
Andover Jct.

TRAIN MOVEMENTS

1. Eastward trains are superior to westward trains of the same class.
2. Double tracks are in service between Mansfield Street and “G” Tower. The normal position of the switch at Mansfield Street is for the Eastward track.
3. Absolute-permissive automatic block signals are in use between “G” tower and Maybrook.


Notice under Train Movements above, #3. In an APA system, different than a CTC system, a train, except at Absolute signal (those at passing sidings), a train may stop and then proceed and then the signals between passing sidings just help space trains out, keeping a free block between those traveling in the same direction. In opposing directions you should not be allowed to pass the red signal at a passing siding, you need to wait till the opposing train passes.
