Gromit, so you reckon that Branson and Virgin, knowing that the train was ram-packed, claimed that it wasn't and then published pictures showing that it was, contradicting their own claim?
And that Corbyn happened to catch a ram-packed off-peak train at the very instant he wanted to film one.
That all seems very unlikely, and the CCTV evidence does not back it up.
This is what one could reasonably call a "ram-packed" train and I have been on many journeys like this, both before and after nationalisation:

This is what one might unreasonably insist was a ram-packed train:

It's well known there's a problem with the railways. That doesn't mean that Corbyn isn't a liar, or for that matter that renationalisation will fix the problem.
