The Society still has one or two Mk 2 vehicles at Whitehead for future restoration.
For those who don't know, the Society's stock of Mk 2s consists partly of vehicles from the original 1970 NIR "Enterprise" set, when the trio of ill-fated "Hunslets" were introduced. They looked very modern among NIR's increasingly dilapidated MED, MPD, AEC and BUT railcars, and elderly steam stock carriages. I remember seeing them for the first time when they were about a week in traffic.
Other RPSI vehicles include ex-British Rail stock which actually never ran in Ireland at all, plus one or two that came from BR to NIR, to be used as 80-class centre cars or Enterprise stock.
And one or two are ex-CIE / Irish Rail.
I know that there are a couple of folks on here to state which is which. It's on the RPSI website anyway.
The Society has four genny vans - two BR type and two "Dutch". Currently, the former are in Dublin and the latter at Whitehead. In each case, one in use, one not.
