Flying back into Manchester airport the other week, and catching a TPE to Newcastle, I was amazed to see that a train for Windermere had 6 coaches, and left almost empty, whilst the 3-coach TPE was rammed from the outset, with the pitifully inadequate luggage space for an airport service immediately full, and the remaining luggage lying all over the place, and people standing/sitting on and around it. Ludicrous.
There are no Windermere services that are 6 coaches. It would have either been a Windermere service attached to an Edinburgh service or a Windermere service attached to a Blackpool service.
