    A High Speed Switch

    A key part of the operation of any conventional railway is the safe and reliable operation of Switches and Crossings. Working with the department's vehicle dynamicists, the Track Team have developed a number of novel solutions to the evaluation and evolution of S&C design through the use of dynamic simulation.

    Much of this work has come about through a strong relationship with London Underground Limited, Tube Lines and Metronet, investigating incidents such as the derailment at Camden Town in 2003 and on other high profile projects such as the redevelopment of the White City Sidings.

    Joss Apps of the Track Team

    The team has also been a major player in the development of VTISM - the Vehicle Track Interaction Strategic Model. This is a validated computer model used to determine the financial implications of changes to the wheel/rail interface. To date, it has been used to evaluate the case for modifications to Mk IV passenger rolling stock, for cost modelling on Trans Pennine Express and First Great Western routes, and as part of the evaluation of the various options for the High Speed Train (HST) Replacement Programme - also referred to as the Intercity Express Programme.
