This research intends to investigate the discrepancies between the maximum vertical dimensions within different gauges, which could create safety issues where such exceedances occur in the vicinity of live overhead wires. The results of this piece of work needs to provide robust evidence to inform the creation of a technical note and potential changes to gauging and electrification standards.

The objective of this research is to define a set of standardised tram-train platform arrangements suitable for use in Great Britain. These arrangements will help support safe, accessible, and cost-effective delivery of future tram-train schemes.
The project will:
•Develop practical platform interface designs that accommodate tram-train vehicle characteristics, accessibility requirements, and operational constraints such as curvature, cant, and clearance for the largest rolling stock likely to pass the infrastructure (typically freight services).
•Support consistency across future schemes by providing clear, annotated arrangements that reduce the need for bespoke infrastructure and improve design efficiency in early project stages.
•Inform national standards development, by providing evidence-based recommendations for updating existing infrastructure guidance or supporting the case for a dedicated tram-train platform standard.
•Engage relevant industry stakeholders to ensure the outputs are feasible, widely applicable, and aligned with safety, operational, and regulatory expectations.

The aim of T1398 is to generate and apply the methodology needed to prioritise and make the case for interventions to make boarding and alighting more accessible.
To achieve this, the project will:
•Define a range of Boarding Categories based on PTI geometry data and human factors. The thresholds between these categories should be driven by the proportion of passenger persona groups who can board independently and safely.
•Assign platform/train pairings across the network to the Boarding Categories, determining the most appropriate way to capture each pairing given multiple points along the length of platform and multiple doors on trains. This will deliver an understanding of the distribution of actual platform/train stepping arrangements across the categories. This insight must be presented in a way that enables industry to prioritise action and consider solutions for improving stepping arrangements.
•Develop a benefit-assessment methodology to assess the value (financial, economic, and societal) resulting from removing the less accessible arrangements from the GB network or partially improving them (e.g. allowing for one carriage of a train to have level access).

The aim of T1399 is to establish the evidence base and practical framework required to plan interventions that improve boarding accessibility at the PTI.
To achieve this, the project will:
• Identify and review interventions: Produce a comprehensive review of national and international interventions to improve boarding (infrastructure-borne, train-borne, hybrid, direct, and indirect). For each intervention the following will need to be considered: feasibility and suitability, technical and operational constraints, expected impact on boarding, and indicative costs. The review will recognise and capture in meaningful ways that these may vary by location and fleet characteristics.
• Develop a framework to organise and evaluate interventions: To support decisions, interventions will be categorised and assessed within the context of real-world ‘improvement windows’ associated with planned capital investment (such as fleet overhauls, new train procurements, station upgrades, platform rebuilds/extensions, and track renewals). This framework will support decision-makers in identifying interventions available to them and comparing their impact. To be helpful, such a framework needs to reflect differing local infrastructure conditions and rolling stock configurations.
• Develop and assess possible plans of action toward independent boarding: For agreed scenarios representing different levels of investment and timescales, the research will assess how different types of interventions could be combined and sequenced to deliver the greatest accessibility improvements. The analysis will remain at a strategic level, using representative examples and benchmark cost data rather than site-specific designs or surveys, and will balance accessibility goals with financial and practical constraints.

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.

At the highest level, this work package seeks to provide missing empirical data which will support decision making and modelling to better understand how the behaviour of freight braking systems impact on the generation of wheel flats.
This project will seek to characterise and document the behaviour of freight braking systems in real world settings. In combination with the other work packages, the outputs of this study will be used to inform the conclusions of the project overall and will provide useful input to other research activities on freight safety. Specifically, the outputs from this work package will support the research in characterising longitudinal compressive forces in freight (T1352), and the investigation into the factors impacting freight braking in low adhesion (T1351).
The outputs will be achieved through a variety of static brake tests of real freight trains. The specific objectives of the project will be to:
1.Identify suitable testing parameters or categorisation to prioritise testing and agree a test regime.
2.Understand the performance of different locomotives.
3.Understand how braking behaviour varies with different vehicles, brake setups and components.
4.Understand how brake timing and brake force varies down the length of a long train.
5.Understand how different charging/overcharge procedures influence the behaviour of braking systems.
Whilst delivering these objectives will have implications on freight braking and deceleration performance. The primary objective of this work is to support research in the topic of freight safety.
