This has got to be the loudest train ride I was ever on and the coldest as well! We were deep underground and the temperature remains low wherever you go, the same all year round. The young lady on camera took us on a wonderful guided tour and she spoke great English, but as you see she got a little cold during the train journey! This underground fort is well worth a visit and many things are still in working order! Apologies about the bad video quality. It was darker in real life than it looks on the clip.....
