I caught this program on radio today, almost by accident. Fascinating stuff. It's about the so called 'parliamentary trains'.
If you have a spare half hour you could do worse...

Thanks for posting, Allan. Very interesting. I had seen a TV program about these Ghost trains, but that was several years ago.
Yer welcome Malc. That program is from around 2010 I think. Most stuff is repeat broadcasting on Radio 4 Extra but they do find some gems from time to time. I thought it was fascinating. Money down the drain!
