[0.15.28] Rail engine/car location decals don't display

[Elan]

With storage chest in hand the decals show on this straight section when the cursor is within roughly 5 car lengths of the station.



But not here when the cursor is well within 5 car length but the station and cursor are separated by a curved section of track.



Maybe not a bug but is unexpected behavior.

There is no station on this straight track so there are no car positions to display.

[Bilka]

There is a station right before the cruve, and its five wagons should extend behind the place the cursor is at, so it should show the outlines.

There is no station on this straight track so there are no car positions to display.

There is a station and there are car positions to display because they will display when I mouse over the station. But they won't display as they typically do with a chest or inserter or pump in hand when within a certain range of the station.

We (and therefore the game engine) assume train stations are entirely on straing rail segments. As far as I know, pumps won't even connect to fluid wagons in that station. Inserters would pick up from cargo wagons, though.
