Another classic book it sure is “British Railway Track Design, Construction and Maintenance”, edited by Geoffrey H Cope and having around 40 contributors for writing the 30 chapters of this essential track compendium. Its last six edition was published in 1993 by The Permanent Way Institution. Presenting the essential principles but also the British specifics…
The slides of the presentation I gave in November at the West of England section meeting of the Permanent Way Institution: The main topics presented: – Cant parameters definition. The origin of the 11.82 (UK) cant constant. Ways of applying cant. – Track geometry recording. Track Quality Standard deviation. Inherent standard deviation. Quality bands…
The good old times Since the early beginnings of the railway, the track engineers were aware of the centrifugal forces influence to the train riding when passing through a curved section of track. To compensate this influence, the track was inclined laterally by creating a positive level difference between the outer and inner rails of a…
A railway vehicle moving along a circular curve is subjected to an inertial centrifugal acceleration (ac), directly proportional with its speed and in reverse proportion with the curve radius. This lateral acceleration is perceived by the passengers as an uncomfortable sensation and, above a certain limit, endangers the lateral stability of the running vehicle. In…
