Driving and operation strategies for traction-energy saving in mass rapid transit systems

In this article, two models for estimating the energy saving potential on a mass rapid transit system are described. The first model is very useful for analysing the energy and the second one aims at estimating consumptions of a mass rapid transit system in a period of time. The latter was applied first to a generic line with six stations and then to line A of Rome metro network. Results of both applications show that headways of 120–150 s are ideal for energy saving as they allow transfers between braking and accelerating trains.
