Good question, I don't.
I was thinking of adding train length limits, but I couldn't come up with a good solution for user interaction.
There are two ways I could think of, but I don't like either:
- some sort of sequence in the stop name, maybe using LTNs signals (for example: [max-train-length][signal-1][signal-0] could represent max train length of 10)
- or to switch to LTNs stations.
Both have problems. More signals in the stop name just make it unreadable and Optera's license doesn't allow for copying of the code. This means I would have to reimplement a large part of train stop management myself (which I don't really want to do :D).
So in short, if you, or anyone, can come up with a good user interaction process, I'll gladly implement it, but for now no train length settings.
