Super Outer Circle

The Outer Circle was a London & North Western Railway service in London that operated from 1872 to 1908. The route was from the District Railway station at Mansion House to Earl's Court, then via the West London Railway to Willesden Junction and then via the North London Railway to Broad Street. Although not a complete circuit, it was one of several 'circle' routes around London that opened at the same time, such as the 'inner circle' that is today's Circle line. Trains would run once every 30 minutes. In 1908 the service was cut back to run from Earl's Court to Broad Street.

The Midland Railway operated a kind of Super Outer Circle from St Pancras to Earl's Court for two years from 1878-1880, via the Dudding Hill freight line.

On 1 February 1872 the London & North Western Railway (L&NWR) began a railway service between Broad Street and the District Railway station at Mansion House via the North London Railway, Willesden Junction, the West London Railway and Earl's Court, replacing a service that had run along much of the same route to London Victoria. This service became known as the 'outer circle' and was worked with L&NWR locomotives and carriages and there was a train every thirty minutes. When the District electrified in 1905, it built electric locomotives to haul the carriages between Earl's Court and Mansion House. The service appears on the 1908 'London Underground' map between Earl's Court and Uxbridge Road as a District Railway service.
