Booking on Cork-Dublin - direction of seat?

[MrX]

I am just wondering when looking at the diagrams on the Irish Rail seat booking service which way the train's actually facing.

Diagram is as follows :

<"engine">-[----a----][----b----][----c----] .......

I have booked assuming that "Engine" = the actual locomotive and ended up facing the wrong way around.

Any suggestions ?

I'm assuming Coach A is at the end of the train on the way to Cork and at the front of the train on the way to Dublin ?
