Ruddy daft idea !
Can you imagine the uproar if someone suggested that we have Men-Only carriages ?
I can remember some years ago, when BR tinkered with the idea of making one carriage No Smoking, but this failed utterly, as everybody had to walk through this carriage in order to get to the Buffet Car ! So just how are the train companies supposed to deal with men walking through a Women Only carriage, in order to get to a cup of tea ?
Anyway, where is the demand for this ?
If we could coral all the drunks into one carriage, preferably the one on the end of the train, well, I might be prepared to support that !
