Caught the sleeper train from Varinasi to Orchha. The train was okay, 3 bunk beds each side of the vestibule. There were bars on the windows - I found out that this was to stop thieves on the platform grabbing bags and jewellery from you when you are sitting in the train next to the window. When you use the train facilities you can see the tracks moving through the hole in the bottom of the toilet - no illusions of sewage treatment there. Apparently the natives don't travel in the roof any more but the train doors open fine so you can hang out if you wanna!
