Supply of Door Components for the Central Line Tube Stock.

TfL does not have the Technical Information such as, specifications, details of materials used & drawings for the above parts in order to effectively conduct a bid and source them from the open market.

The use of alternative parts sourced from suppliers other than the Original Equipment Manufacturer (OEM) for the overhaul of door systems presents a significant risk of component incompatibility and may introduce disproportionate technical challenges during operation. Such deviations from OEM‑specified parts could compromise the reliability and safety of the door system because door components are safety critical and therefore must meet the exact OEM specification, safety standards and certification. Use of non-OEM parts could potentially result in incorrect door operation (e.g doors not closing correctly/ door jamming or a in service failure) which may require the train to be removed from service and increases the risk of passenger entrapment or other door related safety risks. Procuring OEM door components ensures full technical compatibility / compliance, reduces safety‑related risks, and supports the continued safe, reliable operation and maintenance of the Central Line fleet's door systems. In view of these points TfL is sourcing these parts directly from the OEM.
