To get any sort of more intelligent train management/schedule management one pretty much has to disable train stops based on circuit network conditions. From what I understand this is the proper way to set things up.

For eg. I have a supply train with two stops, "loading" at the main base, and "supply" at an outpost. I set the train to go to both stops and wait until it's idle before continuing to the next stop. At my outpost, If I don't need any items, I disable the stop. If I need something, like walls or laser turrets I enable the stop.

The train does the correct behaviour and departs for the outpost when the outpost needs supplies, but when it tries to leave from the main "loading" stop, it keeps flashing up "no path" if the "supply" stop is disabled. I searched up and down my tracks for a while before I figured out that there is nothing wrong with my tracks or light (which is why "no path" shows up in other situations), and it was just because all the stops were disabled.

The train should not flash "no path" ever, if all stops are disabled except the current one where it is. It should just indicate (via a colour of the stop name in it's GUI that it's disabled) and just stay put at the current stop it's at.

This is a feature request - not a bug

Actually I think I had 2 stops with the same name and one was unreachable, and the train might have been trying to go there. Once I removed the unreachable one, the "no path" messages stopped.

Perhaps a better indication of the error condition, that some stops are uncreachable, and some disabled would be good. But it does work correctly when I removed the unreachable stop it seems.
