Hey,

I've build an oil setup and am willing to transport the oil to the refinery etc. by train,
loading the train works just fine, but at the station where the pumps are supposed to take the oil into the pipes it just doesn't work.

I don't see what I'm doing wrong, can anyone help me?

Regards
Felix

Your train stay with rotation. It means that you don't use stations. The placement must be very precision, 1/4 tile is too far.

If any part of a fluid wagon train is on a curve the pumps will not connect.(Edit: to any wagons after the curve)
If you want your setup to work you must have the entire train including the locomotive's on straight rails.

Also, locomotives have to be in an exact (or very nearly exact) position to connect, so they only work if sent to the station automatically or placed at a station using the guide. Since the engine is on a curve, I assume you parked it there.
