MOST interesting what’s behind the engine - the tin van will be newspaper traffic between Connolly and Portadown / Belfast - but behind that - an NCC “brown van”!!
These were regular enough carrying newspapers and mailbags between Great Victoria Street and Portadown (I think the picture is near Moira, where the main line crosses the Lagan Navigation Canal), but far more often on the back of railcars, rarely in a goods train.
As an aside, I’m unaware of any reports, let alone evidence, of any brown vans ever seen south of Portadown. While Warrenpoint was still operating, it was all GNR (and CIE) vans to be seen in those parts.
