This is a topic that has been discussed many, many time in the IET Railway Technical Network Executive Committee meetings, with lots of different views and opinions on what is needed and how it could work. Anyone got any thoughts on this?
I guess its how things fit with energy systems overall, and its complex because electrification has given some advantages in being able to fit motors underneath carriages , but obviously a system that is on or off could use less energy overall if we get to KJ calculations , and not all electricity is from renewables , depends what your view is I guess theres some figures in IET magazine on how much current railway uses in diesel terms .
