OK, let's takes this hypothetically overcrowded train and tack on 2, or 3, or even 4 extra carriages. Enough carriages that every passenger; the elderly, the disabled and durham's 40 years old son and his family, all have a seat, whether they've pre booked one or not. Perfect. Now, that train is much longer than the vast majority of station platforms can accommodate. We know this because vast amounts of money have been spent at Durham station, earlier this year, to extend the platform by 40ms. Similar work is being undertaken at Manchester's Piccadilly Station, for the same reason. Until all of the station platforms are sufficiently long enough to allow a train to disembark it's passengers safely, they are not allowed to stop at those stations. elf and safety. When the work to extend station platforms is completed, across the country, I suspect that overcrowding on trains will become less of a problem. and Corbyn will have to think of a new wheeze for publicity . Until then, just reserve a seat and be prepared to ask to ask anyone sitting in it to move. Please.
