I can remember them actually coming through Taunton on the odd occasion, with what must have been the last of the Ocean Liner boat trains, to about 1962 I guess. The Up trains generally followed the Up Cornish Riviera, similarly nonstop Plymouth to London at the time, about a block behind; the Riviera passed, then just a few minutes later all the Up distants came off again. Cleanest loco of the week, a credit to the Laira team, invariably a Castle to the end, and maybe 4 or 5 saloons. By then there was hardly anyone on board. I believe the last ship that came in via Plymouth was from South America; it carried on to London or elsewhere, but the passengers saved a day.
