SELLA CONTROLS is pleased to announce the contract award from Bombardier Transportation for the supply of Tracklink III equipment for the London Overground Rolling Stock
Systems integration specialist SELLA CONTROLS is pleased to announce that we have been awarded a contract from Bombardier Transportation for the supply of 59 off Tracklink III readers and software development of a new SIL2 protocol interface along with SIL2 software development for the function of AC/DC auto-changeover. In addition to this functionality the Tracklink III readers will also be used for Selective Door Opening (SDO) and Correct Side Door Enabling (CSDE).
The equipment will be fitted to 45 x 4 car Class 710 EMU trains (also known as LOTRAIN) and will be operational on the London Overground network. The trains will be delivered in two sub-classes; an AC only version for use on the West Anglia and Romford-Upminster services, and a dual-voltage version for the Watford DC and GOBLIN services. The dual voltage version will be fitted with 2 off Tracklink III readers to carry out the functionality of SDO, CSDE and AC/DC auto-changeover.
The AC/DC auto-changeover function is used to raise/lower pantographs and raise/lower shoe gear as the train goes from an AC traction area to a DC traction area and vice versa.
