Train Gate Sensing : Bug or Working As intended

[Trepidati0n]

If I stand on a train gate (with walls on the side), the gate lights turn on (e.g. green) and the logic turns my lamp on.

If I do not stand on the train gate (with walls on the side), the gate lights turns off (e.g. red) and the logic turns my lamp off.

These both make 100% to me

However, If I do the same thing with a train, the light is green indicating the gate is open but the light does not turn on.

Note, the light does flicker as the train is moving but not static. Thanks!

In short: The gate is trying to close right after the front part of the train passed it but the rest of the train is preventing the gate from doing so. This mechanic has the effect that there is no signal while the gate is still open.

Thanks. I would like to have a "gate state" variable I guess.

To the typical person..this behavior is "not obvious" with any of the indicted information on the tool tips or displayed information.
