Railway Mass Public Transport Case Study



Within the UK Railway Network, there are branch lines that are not connected to each other by catenary lines. To effectively bridge the non-electrified section of otherwise electrified routes, a leading manufacturer in the railway market has developed an Independently Powered Electrical Multiple Unit (IPEMU).

This train uses a small, lightweight, yet robust set of U-Charge batteries to power the train between branches, thus saving from the huge expense of adding overhead electrical lines.
