Railway operators and infrastructure companies strive to optimise the flow of passengers on and off vehicles whilst aiming to minimise accidents at the Platform-Train Interface (PTI). An ideal solution (already available in some situations) would be a step-free access to aid efficient boarding for everyday passengers and those with additional needs or reduced mobility. Out of many solutions existing today, a ‘kneeling vehicle’ seems a possible solution due to the opportunity to minimise the step and gap distances. In this paper, the viability of an assumed kneeling mechanism retro-fitted to a contemporary suspension architecture is assessed by evaluating the possible improvement in the step/gap distances based on a detailed model of suspension movement. It is shown that for many different infrastructure scenarios that significant improvements in the PTI are shown for a modest and achievable kneeling action. This paper also address fundamental operational concerns of a kneeling vehicle by assessing gauging (with respect to infrastructure and adjacent vehicles) and pantograph interaction.
