Institution of Mechanical Engineers, London
Free and open to all
Magnetic Track Brakes (MTBs) are a form of brake, mounted on the bogie frame between the wheels. When the MTB is lowered to contact the rail, a magnetic clamping force is developed between the MTB and the rail. Friction between the MTB and the rail creates a braking force which contributes to train deceleration.
MTBs are not routinely used on Great Britain (GB) mainline rail, although they are used extensively throughout mainland Europe and on GB tramways.
The presentation will explore how MTB’s work and the potential compatibility issues with railway infrastructure, and will also describe the steps currently being taken to encourage the introduction of MTBs on GB Mainline rail.

Paul Allen: Assistant Director, Institute of Railway Research, University of Huddersfield
As assistant director of the Institute of Railway Research Paul is a recognised expert in railway vehicle dynamics and wheel-rail interaction. His main research activities are in the field of wheel-rail contact and computer modelling of railway vehicle suspensions, a small and highly specialised area which has a major influence on the behaviour of railways and track. He has been working in this area for over 15 years and has built up a substantial international reputation for the work carried out by himself and the team. He has published widely in the field and is a co-author of the ‘Handbook of Railway Vehicle Dynamics’ which includes contributions from many leading experts and is the established text in this field.
