But we can't have the for practical reasons, so talking about them is pointless.
Um, it's not what the TOC's "want", it's what the passengers want. Most passengers want the maximum number of seats so they can sit down. You can't have your cake and eat it. Given the limited space the railways have to play with you have to choose between more space for luggage or more space for seats, and I'm quite sure most people would vote for seats.
Oh the irony. One minute you complain about high prices (even though Advances can be had exceptionally cheaply) and the next you're claiming to be a scummy fare dodger. If no one pays the proper fare where do you think the money going to come from to pay for the up-keep and improvements of the railway? Not only that but we who pay are subsiding your free ride. I find great pleasure in seeing people like you thrown off the train. In fact since you are a scummy fare dodger your whole argument becomes null and void.
