    Hello, so I am looking through the Manual for the Signals EP from AP and see there are markers to force a signal to a certain aspect, but from what I can tell the signal does change until the train passes it. What I would like to do is force the signal to be red, even before the train passes the marker. Basically, I am going to end a scenario with a train pulling into a station and stopping at a red signal and want to get the appropriate signals before it to step down from yellow to red. How can I achieve this?

    Thanks

    I believe this may help. From the manual, it says:
    'To do this, add ;D=x into either of the two ‘Identity’ boxes. x is the value of the delay in seconds. When using a ‘Force Signal’ marker, if you would like the delay to be infinite and for the signal never to revert to its normal state, make the x value 999. This has many uses but one in particular is for the simulation of a track circuit failure, which would require the driver to pass the signal in advance of the failure at danger.'

    Assuming I read your request correctly, you'll need to use a force red marker and add ;D=999 in the left text box to get the desired affect. You might also need to use additional markers on signals before it for the stepping down but I assume it'll work without needing to do that.

    You seem to have misunderstood how these markers work. A Force Red marker for example will force the signal ahead of it to be red until the train passes the marker. It's not that the signal reverts to red when the train passes the marker, this would be odd behaviour and not really suitable for any normal signalling operations except a rare 'put back'.

    As a result, you don't need to do anything fancy for what you desire. Just place a Force Red between where your train will stop and the signal.

    Thank you, I will give that a try. I guess I was just confused because of the way it was worded, but I agree that it wouldn't make sense.
