Nicholas Tozer published this rather lovely video of a blue ‘Portbury’ operating trains in the early 1990s. It’s amazing to see the differences in the background, like the old sidings, the sleeper wall where the flats near SS GB halt now are. Also note the W.Vincent wagon being used for passengers, these days it is back to being a coal wagon.
