Another unexpected feature of the Citaro - the interior of 64013 is like a sauna now the summer temperature outside has hit 20 degrees C. The situation is compounded by a notice on the few windows that open requesting that passengers do not open them because the air-conditioning won't work with them open - err pardon me, what? Does the air-conditioning actually function on these 17 year old buses? Did not seem so to me.
64013 is also another that jerks as it pulls up and it has broken loose roof ceiling panels which rattle and vibrate on rough roads, aggravated on this bus by hard suspension which I have not noticed on others of the OIG series. Noted too, another tall passenger moving about to try and find a seat with some legroom. Needless to say despite the cosmetic makeover I am very disappointed with these buses.
