Category: Sutton Loop
The Sutton Loop is a part of the Thameslink route. After crossing [Blackfriars Railway Bridge]? into South London, the Thameslink route splits into two branches; one goes via London Bridge to East Croydon and the other heads through Elephant and Castle and a few other stations to run in a loop taking in Sutton and Wimbledon. Trains enter and leave the loop after/before Streatham.
One potentially confusing thing about the loop is that if you want to go to Sutton, you can get there more directly by taking a train which is indicated as being for Wimbledon - and vice versa.
The loop is also known as the Wimbledon Loop, the Sutton/Wimbledon Loop, and the Wimbledon/Sutton Loop.
According to Wikipedia, morning peak trains only run in one direction (clockwise) around the loop.
