You said "while TOCs won't spend money on a solution". They, and the DfT, are spending money on the solution.I'm not going to repeat myself for someone who cannot properly read a post and fails to understand the perspective of someone who is not a regular user of trains. I'm not talking about the future, I'm talking about the here and now. In the 2005 future we were going to have modern electric trains whizzing up and down between London and Bristol in 2016.
I know it spoils your rant, but hey.
