Elsbridge is a village on Thomas' Branch Line in the Els Valley with a population of 500. The nearby River Els flows underneath a bridge (based on the bridge at Maidenhead, built by Isambard Kingdom Brunel) and enters the Sudrian Sea at Knapford.
At one time, Elsbridge was the top station of the Knapford and Elsbridge Light Railway. After the opening of Anopha Quarry in 1924, the line was extended to Ffarquhar. The station is often referred to as "the station by the river".
By the station there is a cricket field.
In the television series, Elsbridge is the junction to a loop line running from Tidmouth to east of Crosby. The station has a large overhead footbridge. There is a small yard and an engine shed situated here as well. It appeared in the first, second, third and fourth seasons.
