Details

This research seeks to develop the evidence base required to inform the transition towards harmonised ACL characteristics across rolling stock operating on the GB network. It will confirm and refine the previously proposed target state for ACL harmonisation (that is BS EN 50388-1:2022 without UKSNC (Umin2 = 17.5 kV)), fully accounting for technical feasibility and economic viability, and develop a detailed pathway from current to target state for existing and future rolling stock. Specifically, the research will address the following objectives: 1.Confirm and detail the target state for ACL harmonisation and the rationale for its adoption: this includes accounting for wider system consequences and trade-offs, quantified associated benefits, costs and risks. 2.Define a transition pathway from current to target state: this includes specifying the ACL changes that are technically achievable and economically justified for existing rolling stock, the ACL requirements for future rolling stock, the role and deployment of dual trains, and the phasing required to reach the target state.

Before you bid on this tender

A quick checklist to help you decide whether to bid and prepare a compliant submission for this energy & power opportunity. Always verify the details on the official source.

  • Confirm the exact closing date and time (and time zone) on the official portal — deadlines are strict and can be revised by a corrigendum.
  • Read the full notice and every attached document, including the scope, specifications and any bill of quantities or terms of reference.
  • Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
  • Prepare any earnest-money deposit (EMD) or bid security and the required formats early; missing or wrongly-formatted documents are a common cause of rejection.
