Direction of travel

[zag]

I'm planning on getting the 1235 Limerick-Dublin this Sunday (after watching Leinster thrash Munster the night before) but on the seat reservations page I can't work out which direction faces Dublin.

The reservation screen has an engine icon, car A and car B and nothing else. I *guess* the engine points in the Dublin direction, but it's also possible that the engine is at the back and there's a drivers section at the other end too.

Does anyone know for sure which direction points towards Dublin ?

Thanks,
