There's disruption on the railway across the South West this morning (5th March) after a fault with the signalling system between Slough and Twyford.
Great Western Railway (GWR) expect services to be fully back to normal by 9am, but they say trains will start running again from 8am.
Instead, those currently departing from Bristol Temple Meads or Bath Spa are urged to go to Reading (on the GWR service from Plymouth)- by the time you get to Berkshire, services to the capital are expected to be back to normal.
Alternatively, you can change at Salisbury, before travelling in to London Waterloo from Wiltshire.
At the moment, almost every service from Swindon to London Paddington shows 'cancelled' on booking websites, excluding a single train.
The booking app Trainline suggests those travelling from Gloucester head to Swindon to catch this sole service.
Trains from Devon and Cornwall appear to be operating as usual.
A spokesperson for GWR said: "Trains between Reading and Paddington are severely disrupted this morning due to signal failure.
"Signalling is now restored and trains are expected to be running again by 0800.
"Some delays are expected for the rest of the day and customers are advised to delay their journey if possible."
GWR say tickets will be valid on South Western Railway services to Waterloo, Elizabeth Line, and London Underground services.
While some London buses will accept GWR tickets.
GWR posted on social media: "Due to a fault with the signalling system between Slough and Twyford, all lines are blocked.
"Train services between London Paddington and Reading will be cancelled."
If you arrive at your destination 15 minutes or more later than planned, you can claim compensation here.
