I'd like a simple visual indicator of which block a rail segment belongs to.

Firstly I feel that it could be helpful in debugging some of the interesting bugs regarding blinking signals.

Secondly it would be a useful tool for the player with helping to answer two pretty common questions when designing rail systems:
1. Why is that signal blinking?
2. Why is that signal red? There is no train that is even remotely close to there?!?!?!??
But it also gives the player a quick way to see if intersections are sufficiently signalled.

Thoughts? Mod suggestions?

That is not only requested as debug option, but in game as "information layer". But I didn't found approbate threads yet (difficulty search).

AFAIK till 0.13 there where for example arrows drawed, which helped to realize the segment borders.

Yes! This would be immensely useful. Debugging train signals is a pain in the neck at the moment. Being able to see a coloured line down the track marking where different blocks end as the rail equivalent of machines showing what they make would be a huge help.

Woohoo! Thank you devs
