Clayton CB40 EMC Testing

    Tribe Engineering have supported Clayton Equipment with EMC testing as part of London Undergrounds CB40 commissioning programme. The London Underground network has a very complex EMC environment due to several legacy signalling systems being present on the routes. In order for these locomotives to haul engineering trains from their home depot at Ruislip to any part of the network (excluding Waterloo and City Line) to support infrastructure works, they need to travel over several types of track circuits…

Clayton Equipment CB40 Locomotive

    This project involved the conversion of a fleet of diesel engineering locomotives to battery/4th rail traction for London Underground. The existing diesel powered Schoma CF-500 locomotives were little used due to the diesel emissions being incompatible with use in LU’s deep tube tunnels. The concept was to take these locomotives and convert them to a “clean” power source. This also needed to be independent of the 3rd/4th traction current rails when being used in an engineering possession (where…

Modular P&C installation and delivery system

    London Underground are planning to introduce modular P&C (S&C) to their network.  Traditionally, complex railway junction layouts have been hand built “in the hole” on site. Modular rail Switches and Crossings (Points & Crossings in LU terminology) is a method of constructing large layouts away from a build site, breaking it down into manageable sections (modules), transporting to site, and reassembling/installing. The problem is how to transport these modules to site and then install them. The solution that…
