Hertford Loop Line
The Hertford Loop is a branch of the East Coast Main Line.
First Capital Connect operate suburban services along the East Coast Main Line south of Peterborough. Trains run along the Herford Loop between Kings Cross or Moorgate and Letchworth, Stevenage or Hertford North. Occasionally, GNER trains operate non-stop along the route when diverted off the main section of the ECML due to engineering work. There is a siding to the north of Bowes Park which is occasionally used to turn around GNER trains heading for the Bounds Green Depot. There are also terminus platforms at Hertford North and Gordon Hill, the latter acting as a terminus during peak hours only.
The loop is about 24 miles long and was opened in three stages between 1871 and 1924. Flying junctions connect each end of the northbound track with the main line. The route is electrified using the 25 kV, 50 Hz a.c., Overhead Line system.
