Why do non of the central trains newer deasil trains (sorry I don't know thier name, they work the citylink services amongst others) have loads of internal doors seperating the diffrent sections of the carriges that don't work! They are hardley ever working, and I've been on when they are working and they make a huge diffrence in terms of noise, but there usually jammed open, or you even have to force them open with your hands! Are they really unreliable? Or do they get turned off for some reason? Just weanted to know for some reason!
Thanks.
Thanks.
