Timetabling - station Stopping positions 27/08/2024 at 20:37 #158333

178 posts 		I am looking for more detail as to what the stopping positions of FX, F, N & NX actually mean.
I know what they stand for and what they do on a basic level (see my attached graphic).


In the forum I found the following:

Then the forced stopping behaviours:
FX = far end exact = 2m short of the signal
F = far end - 20m from signal or whatever defensive driving asks for
NX = near end exact = rear 2m past the signal
N = near end - 20m past the signal or whatever defensive driving asks for. (?)

Adjust then adds or subtracts.
So if you have a train stopping where the loco runs round, you need to be sure there is a loco length clear at the back. So NX+25, or back calculate for an FX and train length.

In this above post extract I am reading 'platform end' where it says 'signal' because not all platforms have signals at both ends.
I take it also that if there is a signal at the far end of the platform, defensive driving rules will override the platform stop position if that signal is on and defensive driving rules conflict with the stopping position.

Please could someone confirm or correct this information

The train now standing on platform 2, should be on the rails

Online 		It should be relative to the location position. The location position will be on one or more TCs. Sometimes the location is simply the TC(s) so near and far are the extent of the TC(s). In some cases the location is at a specific point on a TC, that is set in the data and is the far, end of the platform. There is no concept of platform length as such in the data, other than the residual length of the respective TC(s).

178 posts 		Thanks Peter for an insight into how locations work behind the scene.
For an example if the far end of a location is at the far end of a TC, the I'd assume the FX stopping position will be at the end of that TC, but how far short of the end of the TC will a F stopping position be? Is the difference in distance between the F and FX positions on a per sim basis or the same distance on all sims?

If it is the latter what is that distance and if the former is the a distance that is recommended to authors?

Online 		FX is 2m, not 0
F is usually 20m but may differ with defensive driving settings I think

I don't think this is set in the data, or if it is all mine will be whatever the default is, which appears to be 20m. I don't do much timetabling so have little up to date practical experience to say any more. However, what you quoted in the original post seems right to me from memory save for the reference to signal.
