Decarbonisation of Bi-mode Trains

A GWR bi-mode train (Class 802)

A partnership between industry and academia to decarbonise bi-mode rail transport in the UK.
This project was generously funded by the RSSB.

Project Overview

We developed a detailed computer model of a bi-mode train and used this to reduce their carbon dioxide emissions.

A bi-mode train is one which can draw power from the overhead line equipment (OLE) – the wires that hang over an electrified train track – or diesel engines. We developed methods for controlling the diesel engines to reduce the amount of carbon dioxide they emit under operation.

Results

The controller that we developed in this project showed carbon dioxide reductions of up to 19% for a bi-mode train. A full report on the project is available on RSSB’s SPARK platform.
