in transportation applications. The series is available with between 2 and 5 plug-in positions (MPG2, MPG3, MPG4, MPG5) for the 250 W or 400 W converters and a total output power of 500 - 2.000 W. With different wide-input voltage ranges between 14,4 and 154 VDC, the devices supply output voltages between 12 and 110 VDC. The output voltage operates with an IU characteristic curve. The system can be switched into an energy- saving stand-by operation via a remote control input. Further features are signalling of input and output voltage by an LED as well as a potential-free power good signal. The whole system is passively cooled by convection and is designed for an ambient temperature range of -40 to +70 °C. Visit

Colas Rail buys on-track tamping machines business from Amey
R
ail infrastructure services provider Colas Rail has expanded its Rail Services operations by acquiring Amey’s on-track
tamping machines business.
The £5 million deal comes as public and regulated services provider Amey focuses on its core offerings of asset management, rail projects, metro services, track renewals, signalling and electrification.
Colas Rail already has the largest and most advanced fleet of modern on- track plant in the UK but large rail plant continues to be a major core part of its development strategy.
Stephen Haynes, managing director of Colas Rail Services said: ‘The acquisition will allow us to provide an enhanced service to Network Rail while providing enhanced support and focus to the staff and tampers that have transferred from Amey.’
Lee Jones, Amey’s director of
operations for rail and metro said: ‘As one of Network Rail’s largest providers we remain absolutely committed to the rail market. The tamper machines are a very small part of our business and the sale to Colas Rail is the right fit at the right time for both our businesses’ forward plans.’ Amey and Colas Rail have worked as a joint venture on high output and conventional track renewals for Network Rail since 1998, delivering in excess of £1 billion of railway engineering work in the UK.

London Bridge station roof project completed S
caffolding contractor, XERVON Palmers, has completed, on time and on budget, a 14-month contract worth approximately £20 million to deconstruct the train shed roof at London Bridge station – opening it up to the sky for the first time in more than100 years. The contract was completed without the use of major cranes and with no disruption to station operations or traffic surrounding the venue, with XERVON Palmers running a separate day and a night shift of operatives and managers. The project, which is part of a five year Network Rail-Costain £600 million refurbishment programme to redevelop the historic station, involved creating a structurally-supportive 18,000 square metre protection deck running the full 70m width of the station with around 10,000 aluminium special access panels, 350 tonnes of temporary steel and a secondary mobile access system.
In addition to the design and construction of the mobile protection deck (rolled into place using modern ‘cassette’ techniques), the sequenced, safe removal of the dilapidated, historic, crescent-shaped train shed roof and the creation of a mobile access walkway in the side roofs to remove the roof cladding, XERVON Palmers operatives also managed waste and recycling. More than 1,200 tons of steel was removed (by hand), as well as asbestos, along with rare heritage material in the form of pre-1880 Georgian wrought iron and polished re-enforced glass, which has also been recycled.
NASC AGM The NASC (National Access and Scaffolding Confederation) 2013 AGM took place late last year and elected Kevin Ward as its new president. It also
announced changes to the NASC Council; revealed the winners of the biennial NASC Health & Safety Awards and launched TG20:13 technical guidance. Ward, manaing director of Scaffold Erection Services, takes over for two years, and succeeds Rob Lynch. He said: ‘My message to members is that they must get to grips quickly with this new version of TG20, embrace it and utilise it to their advantage.’ Ward also challenged the NASC membership with the creation of a minimum of 400 scaffolding apprentices during his term as president.
