A few weeks ago I was coming into our passenger terminal on a proceed signal (the equivalent of Clear) and was surprised to find the next signal was at Stop. The speed limit is 10 and we run light trains, so I had plenty of time to stop but it definitely didn't feel right.
Thought it might be a bulb out or whatnot, so I called the dispatcher on the radio to let them know I went from Proceed to Stop. They kindly responded that they decided to hold me for an outbound train, not realizing that this could have been a major issue. The signal system is so old here I that I don't think they even have a time-out function, but there is a rule that dispatchers have to confirm with trains that they can stop before the signal can be changed.
It's honestly (and sadly) somewhat common in this terminal for dispatchers to drop signals on trains, and I've experienced it twice in the last 6 months. I'm 95% sure that the last signal was indeed a Proceed (not Approach Proceed or anything with the "be prepared to stop" qualifier) but of course there's a possibility I misremembered. I haven't reported it to anybody or even brought it up to the union, but it's been bugging me.
What would you guys do?
