London to Glasgow: Train Time by Avanti, the Sleeper, or the Cheaper Coach

London to Glasgow takes about 4 hours 30 minutes by direct Avanti West Coast train, running up to 7 times a day from London Euston to Glasgow Central, city centre to city centre. The overnight Caledonian Sleeper is the relaxed alternative, leaving Euston late at night and reaching Glasgow around breakfast in a bed or seat, saving a hotel night. FlixBus and Megabus coaches take around 8 to 9 hours, mostly overnight, for the lowest fares. Note that Lumo runs to Edinburgh, not Glasgow, so Avanti is the daytime train here. Here is how the options compare.
