Trains running from Bristol to London are suffering major disruptions after a train hit someone on the track.
Buses will replace many First Great Western trains after the collision between Bathampton and Box involving the 0900 BST service from London.
A train service from Bristol Parkway to London is still running, as is a half hour service from Bristol Temple Meads.
Services after Bath will be diverted via Westbury up to London Paddington, adding 45 minutes to journey times.
'Major disruption'
Buses from Chippenham to Swindon have been put in place.
Local services between Cardiff, Bristol, Bath, west Wiltshire and east Somerset are unaffected, although there may be some minor delays.
"This is causing major disruption. It is impossible to give a timescale and we are in the hands of the British Transport Police (BTP)," said a First spokesman.
A BTP spokeswoman said the incident was not being treated as suspicious.

A man and a woman died when they were struck by an 80mph train on a railway line in west Essex.
The incident happened in the early hours at Harlow Mill on the Cambridge to London Liverpool Street line.
The driver of the 0618 BST train from Cambridge told police he sounded his horn and applied the emergency brakes but was unable to avoid striking them.
Train operator National Express East Anglia said some services were cancelled and others would be delayed.
Bus replacements are ferrying passengers between Broxbourne and Bishop's Stortford or Stansted.
A British Transport Police spokeswoman said: "A train driver reported striking at least one person on the line at Harlow Mill station.
"The train was approaching the station, where it was not due to stop, at 80mph.
"The driver saw a man and woman on the track, blew his horn and applied the emergency brake, but was unable to avoid striking them.
"Police can confirm that both people died at the scene."
