It's 2.29am and I'm standing barefoot in a t-shirt on Brest station platform taking a breath of fresh air before the gigantic Russian Warsaw-Belarus-Moscow express train makes its departure for Moscow at 2.52. It's got pretty hot in the four berth carriage we're sharing with two others. The air-con is off because most of the systems are off on the train whilst they change the wheels to fit the wider gauge Belorusian-Russian railway system. You might ask if it makes a bit of noise? I can tell you that it makes a lot of noise.
