The Present 2021

For details and photos of test train running before 2021 see the index here.

The line was leased by LUL in order to test and commission the next generation of London Underground trains, known as Sub Surface Lines (SSL) trains. Serco Assurance were awarded the contract to manage the whole of the test track of behalf of LUL which will give them the opportunity to attract other interested parties to the line.

In October 2013 the BRB Residuary was abolished and the line passed to NR ownership since when various changes have taken place to the OHLE. A class 395 was tested with a different pantograph and a number of Hitachi IEP sets have been commissioned. Several Electrostar EMUs have also been tested

The  line is currently used  to test and commission Bombardier's latest Aventra series of EMUs including the class 345 EMU for Crossrail and 710 for London Overground

I think the main batch of class 720 units (for Greater Anglia) are due to start arriving in the not too distant future, with the Rail Operations Group again handling the transfers to/from Old Dalby.

The continuing delays with Crossrail and late deliveries of class 710 units for the Goblin Line has meant these units being stored at Worksop amongst other sites
