The electric tram-trains will be brought in as part of “improvements”;; in South Wales.

New electric train at a South Wales Metro station.Commuters have been left horrified after being told a £1billion rail upgrade will include trains with no toilets

But one passenger said it was “absolute madness”;; that the carriages will be without loos.

Rail staff admitted they were “dreading”;; the likely problems with the elderly, children, disabled people and drunks.

The Welsh Labour government says the new South Metro project will “provide better options”;;.

Passengers needing the loo will have to get off at a station.

One commuter said it was “absolute madness”;;, adding: “We certainly are going backwards in Wales!”;;

Another added: “No public toilets at the vast majority of stations either.

“I regularly travel from to Merthyr and also Aberdare. Both big towns and not a toilet in sight.”;;

One shocked commenter added: “I have a funny feeling there’s going to be lots of urine on the floor on a Friday and Saturday night.”;;

Transport for Wales said on-board toilets would “significantly reduce capacity”;; and that passengers would always be within a 20-minute journey of a loo.
