25 hours on a train

So we have to joy of having a 25 hour train ride today. Overall it hasn’t been that bad and its gone by much faster then I thought it would. The carriage is completely open with only walls separating the columns of beds. There are six bunks in each cubicle and I have the top bunk from three. There is no room to sit up and little room to move but thankfully we also had the bottom two bunks so we on them for part of the trip. This is also the longest trip so after this one it all should get easier.
