TRANSPORT FOR London has published a Periodic Indicative Notice seeking bidders for the design and build of a Mechanised Renewal Vehicle (MRV).

TfL aims to improve the process of track renewal in London Underground’s deep tube tunnels, which is currently labour-intensive, with the aim of the procurement being to improve workforce health and safety while unlocking efficiencies in the track replacement process. Through the procurement a supplier will be required to present a design that will allow for the installation of plant on three refurbished wagons supplied by LU.

The MRV will need to achieve a higher output of track renewal per shift, faster mobilisation of materials/tools to site, a faster setup time, improved health and safety and a reduced cost per metre of renewed concrete.

It will be hauled and powered by the LU battery locomotive. TfL says this is first phase of the project, with later stages focusing on greater mechanisation to achieve higher levels of productivity.
