Passenger services, all operated by South Western Railway, either loop back to Waterloo by the junctions or continue southwest via Feltham.

Most service to stations on the Hounslow Loop line are provided by trains operating between London Waterloo and Weybridge via Staines.

As of December 2023, the typical weekday and Saturday service is 2 trains per hour in each direction to and from Waterloo.

At peak hours, additional trains running do not serve Staines and Weybridge, but rather travel in a loop to and from Waterloo via Hounslow and Richmond.

[9] The scheme, known as the West London Orbital, would involve the re-opening of the Dudding Hill Line to passenger services and running trains from West Hampstead Thameslink and Hendon via the planned Old Oak Common Lane station.
