The brand new Elizabeth Line trains have an alleged fault which could injure people, a whistleblower has claimed.
Around 70 of the line’s new trains are fitted with 7KG metal boxes close by the passenger doors, which are reportedly at risk of blowing off the train from a build-up of gas.
The manufacturing company, Alstom, denied anybody was at risk and said it was rolling out a new component at the end of the month to fix the issue.
