Further testing delays rail system arrival time

Network Rail has again delayed trials of the troubled GSM-Railway (GSM-R) communication system.

Tests of the secure voice and data technology intended to improve links between drivers and signallers had been scheduled to start in Strathclyde this month (Computing, 17 August 2006).

But software upgrades needed to improve usability of the system have pushed back the trials to the end of the year.

‘There is a considerable amount of testing required to ensure the system works and is absolutely safe,’ said a Network Rail spokesman. ‘Siemens, the technology provider, is testing the in-cab radios off-site and only after that can a live trial of the system begin in Strathclyde.’

The project was initially set for completion by 2008, but budget constraints delayed it first to 2010 and then to 2013.

The spokesman says the delay will not affect the £3.7bn European Rail Traffic Management System (ERTMS), a continent-wide safety and interoperability system reliant on GSM-R.

ERTMS involves transponders recording a train’s position as it passes certain points and sending details via GSM-R to onboard computers that can automatically apply brakes if trains get too close.

John Cartledge, safety adviser to rail consumer watchdog Passenger Focus, said: ‘It is a pity it is taking longer than expected but with new technology there will be unexpected hiccups.’

A spokeswoman for the Rail Safety and Standards Board says it is vital that GSM-R trials are developed properly and do not affect existing operations. ‘We want to see the trials succeed even if it takes a while to get them up and running,’ she said.
