Caroline Pidgeon said: “TfL needs to show real urgency in tackling what appears to be significant waste in telecoms. It seems that these savings are low-lying fruit, which TfL should have picked a long time ago.”

IIPAG says TfL is addressing the challenge of becoming more self-supporting following a cut in DfT funding. But the new funding dynamics, combined with increasing demand and the growth in the range of potential schemes, mean TfL has to demonstrate the priority and value of its investments are fully justified.

TfL said it is working hard to rationalise the business cases for its investments. But it also says that given the “legacy complexities” and the “mission critical nature” of the assets, a key principle will be to transition the least critical services first, irrespective of the business unit, and focus on more mission critical services once the approach has been embedded with confidence. “TfL would welcome the IIPAG's support in helping to achieve this,” it added.

GSM-R telecoms fitted in Merseyrail’s ageing tunnels
Adam Hewitt reports on a successful telecoms project to upgrade Merseyrail tunnels for Network Rail.
lan Dick Communications (ADC) has just completed a six-month project to design, install and commission a GSM-R ‘leaky feeder’ system within the Merseyrail tunnel structure as part of Network Rail’s nationwide GSM-R deployment.
A
Nearly 15km of wireless infrastructure was installed, on time and to budget, under the GRIP 5-8 contract. ADC also delivered the GRIP 4 design element of the programme.
The new system will allow for a seamless link- up of communications between tunnel and over-ground GSM-R coverage, and it has also been designed to integrate with emergency services’ UHF applications in the future. ‘Leaky feeder’ systems use the cable itself as an extended antenna, mounted via cable hangers in this case.
ADC said the strict deadline and challenging 82 | rail technology magazine Aug/Sep 14
environment required meticulous prior planning of the works, from the safety aspects to the supply chain to the logistics management.
The planning was done at the company’s Scunthorpe head office, with site deliveries on a ‘just in time’ basis.
Work took place both in Victorian brick twin- bore systems and smaller, single-bore versions from the 1970s, with a sprayed concrete and concrete ring construction.
ADC and its sub-contractors worked during four-hour night-time possessions, during which the third rail was isolated.
Ben Quinn, senior programme manager for GSM-R at Network Rail, said: “This was the first major project within the GSM-R Programme where we took the decision to lead with an experienced telecommunications
solutions company. ADC performed a crucial role in the completion of the upgrade to the Merseyrail telecommunications infrastructure, the final completion area for the nationwide GSM-R roll-out.”
The Network Rail Lifesaving Rules were “rigorously applied” throughout the project, with no recordable accidents.
ADC managing director Jason Pearce said telecoms is becoming a more important sector within rail, adding: “The Merseyrail project is another example of how our professional project management and design, experience with large telecommunications infrastructure roll out, are used to effect to deliver a quality outcome on time and on budget for our customers.”
