Siemens Commissions GNGE Phase

Following a ten day blockade, Siemens Rail Automation successfully commissioned Phase 3 of the Great Northern Great Eastern (GNGE) upgrade programme, with the railway being signed back into use at 04:45 on Monday 14 April 2014.

The commissioning follows the successful completion of Phase 1 in January 2014, and represents Siemens’ third major modular signalling installation in the UK. The adoption of modular signalling for this phase has delivered significant operational benefits, with the use of the company’s off-site, ‘hangar’ facility enabling testing to be completed in factory-controlled conditions, greatly reducing the time required for on-site testing.

Covering 32 miles of railway and five manually-controlled barrier (MCB) level crossings, Phase 3 was a major project in its own right, covering the re-signalling of the GNGE route between the northern fringe with Lincoln signalling control centre and the southern fringe with Blotoft signal box control area. The project also had fringe boundaries to the east and west with the Sleaford East and West signal box control centres respectively.

Given that the other single line systems in the area were not to current standards, the single line fringe works proved to be particularly complex, with a requirement for the GNGE solution to be consistent and to maintain compatibility.

The scope of Siemens’ work included the commissioning of 38 VMS LED signals, 70 object controller installations, five modular equipment housings (MEHs), 93 power boxes, 104 axle counter sections and 36 automatic warning systems fitments. The delivery team also commissioned the company’s modular signalling solution for a number of level crossings (four of which were converted to MCB with object detection (MCB-OD) operation) and the project saw the first application of a ‘flashing aspect’ solution being driven by Siemens’ Trackguard WESTRACE equipment.

Commenting on the work, Siemens’ Senior Project Manager, Paul Carlile, said: “Having worked in close collaboration with Network Rail and the other GNGE Alliance partners, we are delighted to have successfully commissioned this technically complex and challenging project. The adoption of modular signalling has been fundamental to the delivery of the whole scheme, representing a major element in four of the programme’s five phases. We now move on to Phase 4, which is scheduled to be commissioned in August 2014”.
