Level Crossings, accelaration,decelartion
Level crossings are a significant safety problem associated with risk to passengers and personnel. The best strategy for improving level crossings is to close them or construct grade separations. Level crossings can be upgraded with the latest available technology.
These factors depend on locomotive and train formation characteristics which are not in the purview of civil engineering. But the time taken for acceleration and deceleration will greatly affect the average speed of high speed corridordrive movie download
