Does train overcrowding pose serious dangers?

Train passenger safety needs reviewing in light of warnings that overcrowding is set to get much worse, the chairwoman of a Commons committee says.

Louise Ellman, who chairs the transport select committee, is calling for rail health and safety legislation to be looked at again.

She said train passengers were often standing "for far too long".

The Rail Safety and Standards Board, owned by the train operating companies, denied safety was being compromised.
