Trespassers are affecting the railway at Richmond this evening.

SWR has said that trains may be canceled, delayed or revised because of this problem.

In a post on social media site X (formerly known as Twitter) SWR said: "At this time, we estimate that disruption to our services will end at 18:30.

"The line towards Clapham Junction is blocked and your journey is likely to take longer.

"We will let you know if this changes or when we have more information."

We will update this article if anything changes.
