- - A split second of lag (at least when placing rails, this is true, not sure about signals)
- A certain set of trains will ignore the chain signal they are waiting at for a moment, maybe 1 frame. The train's front headlight may flash, and the train will move forward a small, sometimes imperceptible amount, and immediately stop. I'm just calling this a "budge".
The same set of trains also budge every 3s or so.
I do not know why only a certain set of trains will budge (as opposed to ALL trains waiting at signals).
Trains idly budging
Trains budging on signal placement
Trains passing chain signals
