The Alstom/Serco/Metronet/NR years 2007 - 2021
Following Alstom's abandoning of the test track a number of
Serco/NR test trains operated on the line prior to the changes when Metronet
moved in. The line was leased by Metronet (now 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 Metronet (LUL), which gave them the opportunity to attract other interested parties to the line but there have not been many takers. Since October 2013 NR have taken over following the demise of BRB Residuary In April 2021 GB Railfreight took over the operation of the test track |
