S&T Support for PL and S&C Track Renewals

The delivery of Network Rail’s £3.5 billion track renewals programme comprises of three major rail companies, Colas Rail, Babcock and Amey Rail. Under this arrangement the railway network is then subsequently divided into specific geographical areas covering all of the UK’s main and branch lines.

Working with Colas Rail who are one of the country’s largest track renewals organisations, RT Infrastructure Solutions (RTIS) provides highly skilled signalling support for both plain line and switches and crossings (S&C) projects on Network Rail’s infrastructure.

Track renewals are undertaken during pre-organised possessions, which can range from overnight occupations of the railway, to full weekend closures and on occasions major blockades.

Through careful planning and coordination with Colas signalling managers, RTIS provides competent and skilled IRSE licensed signalling staff who are capable of disconnecting, re-connecting and then testing signalling assets under SMTH /G110 procedures. Track renewals possessions are normally very intense and provide the main contractor and its sub contractors with a true test of its capabilities. Under normal circumstances the possessions are kept to a minimum and are signed back into use ready for commuter traffic the very next day.

Since supplying skilled signalling staff to Colas Rail on these works RT Infrastructure Solutions has accrued over 40,000 man hours with no reported RIDDOR or major accidents upon the multiple sites worked.
