The Department for Transport has just launched an eight-week consultation to determine the shape of its much-vaunted Great British Railways – our renationalised railway system. Will it, I wonder, be anything like the earlier nationalised incarnation, British Rail (BR)? I do hope so. Because, although BR was disparaged for being old-fashioned and a bit creaky, inefficient and loss-making, I was very fond of those trains of yesteryear.
