Train operator First Great Western has apologised to disgruntled passengers after they were forced to cram into three coaches on an early train in Maidenhead this morning.
The 7.31am service to London Paddington, which is usually made up of five coaches, has run with fewer coaches for two days due to a 'train fault'.
Angry passengers took to social networking site Twitter to complain about problems with the service.
One commuter said: "Why has the 7:31 from Maidenhead only got three carriages? Couldn't get on so going to be late for work, not a good start to the day."
A spokesman for FGW said he could not confirm when five coaches will be restored to the service.
He said: "We are working hard to resolve the situation and we apologise for the inconvenience caused to our passengers."
The company also apologised to passengers who were forced to travel to Reading after the 10.48pm train on Monday failed to stop in Twyford.
A spokesman said a 'computer glitch' meant onboard staff were not aware the service was due to stop at the village station.
