Interesting you say that, I was on one last week and there were a number of windows open.
I was under the impression they were always locked on the Citaros to maintain/regulate the temperature.
Mind, I was glad they were open, because there was someone sitting on the bus who was lifting.
It smelled like they had a couple of steak bakes wedged under their jacket!
