Driving Van Trailer First All trains have a driving trailer, numbered 9001–9004, containing a driving cab, a luggage area and 29 First Plus seats. It weighs 42 tonnes and has a wheelchair space. The cab is only used for services from Belfast, as the locomotive goes north. Trailer First Plus The second carriage in the Enterprise train set, numbered 9101–9104, is an additional First Plus coach with 47 seats (no wheelchair space or luggage area). It weighs 40 tonnes. Trailer Buffet Next coach, numbered 9401–9404 is a buffet coach. Trailer Standard Disabled Space Coach four, numbered 9213–9216, is standard class with a wheelchair space.

Trailer Generator Van Since 2012 electric power for the train is no longer delivered from the locomotive but from a separate generator van. Their final numbers are 9602, 9604, 9606 and 9608.
