Lightweight Rail Signals

As part of its bid to achieve significant cost savings, whilst maintaining high levels of safety and performance, Network Rail has adopted new VMS rail signals.

The new system of support structures and lightweight signals achieved full Network Rail approval in March, and was swiftly selected for a crucial part of the Hickleton and Moorthorpe signalling renewal scheme.

Hickleton and Moorthorpe Signalling Scheme

  • The installation and commissioning of a 5.1m and a 3.3m structure, each with a 4-aspect lightweight CLS, was carried out by a small team without the need for heavy lifting equipment.
  • Both signals and structures were installed on to the preset foundations and set into operation in about 90 minutes (including familiarisation and wiring time).
  • The typical time taken per installation/ commissioning would be 30-40 minutes, for accustomed personnel.

In the original planning, by principle contractor Invensys Rail and Network Rail, the design called for an over-line gantry to support heavyweight Dorman signals at Moorthorpe station. However, with the arrival of the newly approved VMS system offering maintenance-free signals, a rethink resulted in a change of plan, ditching the gantry for the new VMS lightweight system.

The flat-faced LED signals are matched to an equally innovative lightweight support structure. The signals are mounted on lightweight posts which are hinged at the base to make installation a simple job, using nothing more than people and people operated hand tools.

The new signal system has been developed through close collaboration between VMS and numerous rail industry groups, predominantly Network Rail, to produce a system of lightweight signals and structures.

The design has addressed all applications and is compatible for new / renewal schemes, modular programmes and maintenance replacements delivering significant cost savings over conventional equipment and practices.
