## Description
RSSB seeks to procure research to:
•Provide insight on front-end lighting used on GB rolling stock; the assumptions made on their performance (both in term of visibility provided to the driver and warning to people on or near the line)
•Indicate the degree of warning provided (in terms of distance between an oncoming train and the viewer) by front-end lighting that is:
oCompliant with LOC&PAS (Rolling stock - Locomotive & Passenger) NTSN requirements
oInstalled on pre-TSI (Technical Specification for Interoperability) vehicles, including yellow front-ends
•Assess the variables that can degrade or drift and affect compliance with the requirements, and inspection or maintenance required to keep front-end lighting within limits
•Assess the feasibility and potential benefits of automated headlight switching, with or without the added functionality of Adaptive Driving Beam (ADB) headlight technology that is available on road vehicles
Successful delivery and implementation will:
•Provide industry with evidence on the actual warning provided by the lighting specifications and their impact on safety protocols and train operations. This is intended to inform RSSB Standards Project 22-006 (which is planned to be completed by December 2026). This is also intended to inform an update to RIS-3437-TOM Defective On-Train Equipment and Rule Book Module GERT8000-TW5 Defective or isolated vehicles and on-train equipment, by informing what arrangements remain safe when some external vehicle lighting becomes defective, but other lighting remains working.
•Identify the potential advantages and risks of adopting automated headlight switching, with or without ADB headlight technology, considering the need for industry co-ordination.
