I don't get all misty eyed about steam trains and engineering and all that crap - things move on, diesel and electric are better; but I feel like crying when I see all the lines that used to be there and got ripped up. You really could go all over the country by train. I can't imagine what it would be like now to hop on a train in your small town or even village and head anywhere in Europe.
I really really wish the Brecon line was still there. That makes me so sad.
