So what have we learned from today? Well, I didn’t struggle to get a seat on the 11am train from London’s King’s Cross to Newcastle, but that doesn’t disprove Jeremy Corbyn’s experience, and it doesn’t mean that the UK’s rail system does not lack capacity.

It is well known that there are sections of the network with capacity problems – it is one of the stated reasons for building HS2 – and no one regularly using Southern rail at the moment can be happy with the service they are getting.

Is #Traingate a silly season story? Absolutely.

Are Virgin Trains running a flawless system on the east coast mainline? No. And while staff implied our journey was pretty much the same as always, we did not prove that this route is not usually crowded.

Do people have questions about Corbyn’s media operation after this? Yes, they do.

And are they the same people who were already saying Corbyn was incompetent? Very probably.

But I hope this has made people think a bit more about the uses of CCTV by a private company running a train franchise on behalf of the state. And while lots of you wondered about live-blogging a train journey, I can’t think of a better place to interview the people travelling on that route.

Thank you for your comments below the line and contributions; I’m now off to catch the train home. I have not reserved a seat for the trip back, so fingers crossed.
