If you like this kinda thing then I can recommend RAIL Magazine [0], comes out fortnightly (I have a regular order at my local paper shop) and is packed with all sorts of technical goodies about rail ops in the UK and has nice pictures as well :)
That really surprised me. They're running a service from Reading out to Shenfield with no loo. I'd have thought things could get quite urgent under those circumstances.
