RAIL chiefs have today vowed to get to the bottom of train travel chaos that left hundreds of commuters unable to get into London.

A signalling problem, combined with overhead line issues on the London to Norwich line, led to massive delays yesterday, with scores of travellers being turned away from Ipswich station.

The issues followed works carried out on the line over the Easter weekend by Network Rail and come on the back of similar disruption over New Year which led to a £14million fine.

Train operators National Express today said they want to know exactly what happened to cause yesterday's problems.

A spokeswoman for National Express said: “We have asked for a meeting with Network Rail and the regulators and will present evidence to show this was the result of engineering works.

“We can't predict the outcome of that but want to get to the bottom of things to make sure it doesn't happen again.”

The spokeswoman said it was not until about 3am yesterday morning that National Express was informed of the problems.

She said: “That didn't give us enough time.

“We had a number of buses on hand but we didn't have enough notice to do more.”

The rail chaos was caused by a signalling problem in the Shenfield area, which had a knock-on effect across the whole network.

Trains began running again at about 9.20am but services were subject to delays and cancellations.

Services were back to normal today.

Network Rail said they were not working on the signal that triggered the problems, but noticed an issue when they “started up the system”.
