## Description
The scope of materials to be procured is clearly defined in a Bill of Materials (BoM) prepared by LUL Engineering, covering 69 trains, including 2 spares.
The BoM has been grouped into three (3) Lots to facilitate easier tracking, planning and procurement as follows:
•   Bespoke Electronic Communications Network (ECN) Harnesses required by critical DTS (Data Transmission System) and PIS (Passenger Information System) parts. These bespoke components also form part of the design integration for the other saloon systems, i.e. CCTV. The design has been verified and validated.
•   General Electronic Communications Network (ECN) Harnesses; TfL has sufficient data (Drawings, specifications etc.) to allow harnesses and its components to be sourced from a range of suppliers
•   Various electrical components and spares - these parts are mainly off-the-shelf products, with reference to specialised packaging and labelling in the correct sequence to support efficient installation.
