West Coast steams ahead with Transmitton

01 April 2007

Transmitton, part of Siemens Transportation Systems rail communications group in the UK, has won a contract to supply SCADA systems on the Network Rail West Coast Power Supply Upgrade.

The project comprises a programme of works to reinforce the electrification infrastructure, increasing available power to enable train operators to enhance their services. Transmitton is working in the Harker area of the Cathcart region of the West Coast Main Line.

The traction system will be changed significantly, upgrading the 1960s 25kV classic electrification system to a 25-0-25 kV autotransformer (AT) system. SCADA will control a number of new trackside traction substations. These locations will be integrated into the Overhead Line Equipment (OLE) electrification system, which must remain operational throughout the upgrade. Consequently much of the Power Supply Upgrade work will take place on or next to a fully operational high speed a.c. electrified railway, although the SCADA works will be mostly within substation buildings or Electrical Control Rooms.

The Harker area includes substation sites, from Great Strickland to Carstairs, along the West Coast Main Line. Work will be associated primarily with Boundary sites where control is from the Transmitton SCADA master station control system at Cathcart. The work effects mainly the Harker and Great Strickland Feeder Stations. Transmitton will supply fastflex remote terminal units (RTU) and modifications to the cromos SCADA masterstation at Cathcart.

John Weston, account manager at Transmitton, said: “The Harker improvements form the start of an exciting, larger programme that will significantly upgrade the West Coast Main Line over the next few years.”
