Trainspotters have been banned from following their hobby at Cheltenham Spa station during the Gold Cup Festival week,
First Great Western say it is for safety reasons because the station is too busy with so many punters.
Trainspotter Robert Webb, 36, said he was ordered to turn off his camera while filming passing trains from the Cheltenham platform this week.
"I bought a ticket to travel to Gloucester so I thought I’d go to the station an hour or so beforehand so I could film the trains," he said.
"But I was told by a member of staff at the station that I wasn’t allowed to take photographs on the platform.
"He also asked why I hadn’t already caught my train because there are regular services to Gloucester.
"But I don’t see the problem. I had paid for my ticket so I had a right to be there just the same as anyone else."
A spokesman for First Great Western claimed the latest crackdown on trainspotters was due to Cheltenham race week.
"With the increased numbers using the station we have had to restrict access," he said.
"We hope to be able to welcome all enthusiasts back in due course."
There are delays of up to 30 minutes on CrossCountry and First Great Western services between Cheltenham Spa and Birmingham New Street. It follows an earlier signalling problem and it is not known when normal service will resume.
There's disruption on the routes from Bristol Parkway and Cheltenham Spa to Cardiff this morning, that's due to a broken down train between the Severn Tunnel and Pilning.
The vandalism was discovered at 2.30 this morning. Network Rail hopes to have everything back to normal this afternoon.
There are delays of up to 30 minutes on:
Arriva Trains Wales services between Cardiff Central and Cheltenham Spa, on CrossCountry Services between Birmingham New Street and Bristol Temple Meads and First Great Western services between Worcester Shrub Hill and Bristol Temple Meads and between Worcester Shrub Hill and Swindon.
Fewer trains are able to run through the area because of vandalism at Cheltenham Spa and services are liable to alteration or cancellation.
