Night train

I took a sleeper car to Oslo, Norway from Malmo, Sweeden two nights ago...it was a new experience... two bunk beds piled three high in a small room just large enough to get in and out of the bed...I unfortunately was on the top bunk...it wasn't quite bad...the constant movement of the train was enough to get used to and what woke me up was when the train would stop...the air became still...three African guys were in our room as well who thought nothing of talking on the phone all night and conversing with each other...so I have to say next time I will pay the ten extra euros to get a room with only three beds...
