Last night, as I travelled between work and Hels’ home, for part of the journey I was on possibly the oldest train in regular service on the entire UK railway network. It was a diesel unit with three carriages in old green and cream Southern Railways colours. Inside was all wood panelling, curtains and 1950s formica. I reckon it was built in the 50s, perhaps even earlier, and it certainly possessed the charm of the heyday of railway travel. And it had the deepest and most comfortable seats I’ve ever sat on on a train.
