Re-Optimization of Rolling Stock Rotations
2014The Rolling Stock Rotation Problem is to schedule rail vehicles in order to cover timetabled trips by a cost optimal set of vehicle rotations. The problem integrates several facets of railway optimization, such as vehicle composition, maintenance constraints, and regularity aspects. In industrial applications existing vehicle rotations often have to be

Requirements for Wireless Technology on Rolling Stock
2011This paper gives an overview of railway specific requirements on wireless technologies and discusses the influence of different product life cycles in railway industry and communication technology. The main challenges are the heterogeneous communication infrastructure at the wayside and the specific requirements on vehicle speed and geographical ...

The maintenance of electric rolling stock
Proceedings of the IEE - Part IA: Electric Railway Traction, 1950The maintenance of electric rolling stock is an art rather than a science. Existing electric railway systems will have built up their maintenance technique from experience gained over many years, and for this reason the paper deals chiefly with matters likely to be helpful to the railway administration introducing electric traction for the first time ...

METHOD FOR THE COLD ROLLING OF METALLIC ROLLED STOCK
2006The invention is based on a known method for the cold rolling of metallic rolled stock (4) , which for plastic deformation enters a roll gap (3) formed between oppositely rotating rolls (1, 2) on a run-in side and leaves the roll gap on a run-out side, deformation heat that is produced being removed by supplying an industrial gas which is at a lower ...
