This photo shows a Hybrid DMU between Yarmouth south town and Lowestoft in 1970

Class 101 and 105 i think,
Just curious as to why they made these hybrids
question 2: Irish DMU/Railcar
As a lad back in 1969 I went on holiday to Southern Ireland, A town called Clonmel (to visit my grandad)
AT that time they where removing the track from a branch line from Clonmel to i dont know where,
The contractors doing the track lifting where using an old DMU/Railcar as the loco for the track lifting train, At least 2 boogie flats for the rails and 3 or 4 10t flats for the sleepers, and inside the DMU was set up with beds and cocking facilities, Like a home from home, A freindly bunch of men, us kids got to ride on the train a few times,
One day as they where returning,down hill to Clonmel yard, a bit too fast i think, they smashed the DMU into some wagons and compleatly destroyed the front end of the DMU, no one was hurt thank goodness, All the cab controls where smashed and unuseable so they just sealed the vacume pipe and drove it from the other end, No HSE back then
Anyway back to the question, I think the DMU came from Northern Ireland, It was BR green and i think it had a BR type crest on the side,
It had 2 cars with a bit in the middle like this,

The Middle part had 2 bus type engines ofset with a gangway between them and 4 gears i think.
I cant find anything on the interwebs about it,
I bet someone here knows
