NIR was truly fascinating in the early 70s. The NCC and GN sections still retained a real sense of their former identity - even the (Edmondson) tickets on each were different, being printed to former UTA designs on the NCC, and GN-style on different coloured card on GVS to Portadown.
As late as 1977, a Lisburn to Connolly day return was headed "UTA", as old stocks of tickets were being used up.
York Road had what was by then a somewhat dilapidated and random selection of MPD cars in various states, a few MEDs, with other MEDs on the isolated Bangor line, which still retained some BCDR signalling. The GNR section had an equally random lot of AEC and BUT cars. NCC and GN had steam too..... for a short while....
