    Brief

    This procurement seeks approval for enabling civil works at Northfields Depot to prepare the facility for the new 24 Tube Stock (24TS) fleet on the Piccadilly line. The new trains have different dimensions, power systems, and maintenance requirements than existing rolling stock, necessitating infrastructure modifications. Scope includes adjusting track alignments, road layouts, and clearances in key depot areas (roads IE to 19E, 9W to 19W, and 4W to 8W), plus structural and groundworks to enable safe train movements, stabling, and maintenance access. These works are essential to ensure operational compatibility, meet current safety standards, and support reliable fleet deployment. Without these modifications, the depot cannot safely accommodate the 24TS fleet introduction. Suppliers should note this is a critical dependency for the Piccadilly line upgrade programme, directly impacting service capacity and long-term network reliability. Works must be completed to enable subsequent fleet deployment activities.
