Commuters face delays and cancellations on trains via Paddington station on Friday morning (June 17), after a train derailed there on Thursday evening .

Passengers were left stranded for hours unable to get home after the train went through a red signal and seemingly hit an overhead gantry, which led to it coming off the track close to Platform 1 at the station.

No one was hurt as the train was not carrying passengers, Network Rail said as it tried to salvage the situation.

As stranded passengers faced the prospect of not being able to continue their journeys, the news got worse as it was announced by Great Western Rail (GWR) that the disruption would run on into Friday.

Advice was issued to passengers to change their route via London Waterloo or Marylebone, but many were unable to do so as these trains became crowded. Some were even frustrated at being told to go to Ealing Broadway only to be told there were no available trains wen they got there.

Here's some information that might be useful to those using trains in west London on Friday:

What if I am getting a train on Friday morning?

It appeared unlikely on Thursday night that any more trains would be running and delays are expected on Friday morning, when GWR is likely to run half of its normal services.

GWR advises passengers to check its website for information on service delays and cancellations before travelling.

A spokesman said: "We're sorry for the disruption this incident has caused to customers this evening.

"We are working with Network Rail to get things back to normal as safely and quickly as possible, however train services are likely to be affected tomorrow morning.

At the moment, we expect to be able to run around half our normal service into and out of Paddington tomorrow.

"We hope this will improve as further progress is made overnight and we would ask customers to check before travelling tomorrow (Friday) morning."

Which lines are affected?

Trains from Paddington are linked directly to stations Acton, Ealing Broadway, West Ealing, Drayton Green, Hanwell, Southall, Hayes and Harlington, West Drayton as well as going out of west London to places such as Slough, Reading and Swindon.

Heathrow Express services could also be disrupted.

Anyone planning to travel to any of these stations, plus anyone travelling to Paddington or surrounding GWR stations, should expect disruption.

How long are delays expected to last?

Engineers are working overnight to repair the damage caused to the overhead line equipment damaged when the train hit it, but even if progress is made it is likely that services will be disrupted on Friday morning and possibly into the afternoon.

I was stranded last night, is my ticket still valid?

GWR has said anyone who was unable to use their train ticket on Thursday evening will be able to use it on Friday morning.

Can I claim compensation?

If your journey has been affected by the disruption, you may be able to claim compensation.
