T1166 Minimising the impact of ‘high and tight’ platforms on the overall PTI stepgap dimensions RAIL SAFETY AND STANDARDS BOARD LIMITED Tender Closes 31st January

The purpose of T1166 is to investigate high, tight, and high and tight platforms, to identify the extent in which these platforms are adversely impacting rolling stock modifications and the step / gap position at other locations. The research should select appropriate case study locations of high and tight platforms, to identify and understand the range of challenges and potential solutions required to minimise the adverse effect.

Potential challenges and solutions are believed to depend on the platform configuration (e.g. height, offset, radius, curvature, cant, speed). Therefore, the research should focus on the platforms that are believed to most significantly impact rolling stock modifications and the wider network, and include a suitable range of approaches to mitigate the impact.

The objectives for this work are:

• Confirm the current locations of high, tight, and high and tight platforms that are adversely impacting rolling stock design, modifications and making the step gap worse at the majority of other platforms

• Identify the underlying factors causing the adverse impact of high and tight platforms, and the possible solutions that may reduce the adverse impact of high and tight platforms

• Undertake an economic assessment to determine the cost-effectiveness of possible solutions reducing the adverse impact of high and tight platforms, and bring the best wider economic benefits to industry

• Develop a toolkit of options to minimise the adverse impact of high and tight platforms. This should include possible quick wins and transitions to long-term solutions.
