The study results are able to improve the work of designing urban rail lines, choices of technical parameters of trains, layouts of signals and speed limits of rail lines.
Kalker's linear creep theory offers an easy solution to incorporate creep forces into the rail vehicle model as a function of the speed of the rail vehicle.
Network Rail, which is carrying out the work, said the changes would improve the speed of its rail services.
The firm said the work would improve the speed of its rail services.

London First also slammed the speed and quality of rail links from central London to both Gatwick and Stansted.
The British immigrants speeded the building of rail links between the Transvaal and the Cape Colony, and their growing urban populations stimulated the Boers' commercial agriculture.
To make for a smoother ride at higher speeds, the lengths of rail may be welded together to form continuous welded rail (CWR).
Previously, trains remained limited in speed by the curvature of rail tracks.
