Arriva Trains Wales rail passengers in driver's cab probe
An investigation has been launched over claims train passengers travelling from north Wales were forced to travel in the driver's cab for part of their journey because of overcrowding.
Arriva Trains Wales said passengers would not be allowed to enter and travel in the driver's cab for "safety and security reasons".
It said it was looking into the claims but apologised for overcrowding.
The train company would not confirm which service was affected on Saturday.
A spokesman for Arriva added: "Some of our services were extremely busy however trains are built to robust industry standards recognising that peaks will occur due to the unpredictability of customers' travel patterns and there are no defined upper limits on the number of customers permitted to travel on board a train.
"Whilst we did everything we could to provide extra capacity, we would like to apologise to customers whose travel plans were inconvenienced last weekend."
Regarding the issue about passengers travelling in the driver's cab, the spokesman added:
"We are currently investigating an allegation that passengers were travelling in the driver's cab on one of our trains.
"Despite our services being extremely busy over the weekend, passengers would not be allowed to enter and travel in the driver's cab for safety and security reasons."
