Millions of pounds in compensation hasn't been paid out - because rail passengers - don't know they can claim it. The money from rail firms is there for passengers facing delays or cancellations but the Government's Rail Regulator, says most people have no idea.
It says that:
Three quarters of people don't even know they're entitled to compensation.
74% say train companies do little or nothing to let them know they can claim.
That means £90 million is left unclaimed every year.
