What can be done when trains regularly become more crowded? Overcrowded actually, to the point where no more people can fit in.
You might think, have bigger trains, or more saliently increase the service interval so that they arrive more often and are moving more people.
Ah, no, you are not thinking laterally.
Our train company, Connex, and our state government have the answer. Remove train seats so more people can fit in.
Many years ago, a friend said to me that she liked travelling on trams. They were nice and relaxed and friendly, with a conductor to help. She hated travelling on trains though. She thought they were like cattle cars. What would she think now?
