Abstract :
Neasden Depot is currently being upgraded with a new signalling system, new maintenance facilities for “S” stock and a new sub-station for traction (630V DC) and LVAC. Neasden Depot was built between 1933 and 1936 and as such, there is a plethora of underground services including water pipes, power cables and signal cables that require identification/verification and detailed route tracing in preparation for the extensive civil works being undertaken.
