Tube Lines’ major investment in upgrading the Jubilee line is timetabled for completion with the help of a temporary workshop supplied by space solutions specialist, Spaciotempo. Responsible for the maintenance and upgrade of the infrastructure on the Jubilee, Northern and Piccadilly lines, Tube Lines is investing £4.4 billion in a programme to rebuild the London Underground’s busiest lines. This includes a new signalling system, which will allow trains to safely run faster and more frequently.
Based at its Stratford Market Depot, Tube Lines required a temporary working space to enable it to take trains out of service on the Jubilee line for a short period and modify them for the new signalling system, whilst allowing service on the London Underground to continue uninterrupted.
Erected within three weeks, the 140m x 14m (1,960sqm) temporary workshop complies with the necessary standards required by London Underground. Based on a heavy-duty aluminium extruded section, offering a clean, modern look with remarkable solidity and strength, the unit comes complete with a 10-year guarantee.
To facilitate the project, the workshop was subsequently fitted with specialist operational equipment comprising of high lighting levels, a compressed air system for the use of air-powered tools and 28 train-lifting jacks.
Trains are rolled into and out of the facility on a high voltage overhead DC power system where they are fitted with computers and antennae wiring. This enables them to communicate with cables on the track and thus obtain precise details about each train’s location and speed to ensure a faster, more frequent service.
Tube Lines’ lead design engineer, Paul Quintavalle, comments:
“In order for the project to be delivered successfully to a precise time line and in accordance with London Underground standards, we required an immediate and readily available working space without compromising on high quality. The ability to hire the facility for an 18-month period also makes it a highly cost-effective solution.
“The temporary workshop provides us with the additional capacity needed to carry out highly technical procedures away from the operational environment and also makes sure there is no disruption caused to passengers on the Jubilee line.” The line upgrade works, due for completion in 2009, ensures the Jubilee line will be a key transport link during the 2012 Olympics, connecting the stadium in Stratford with other Olympic venues.
