Locomotive 3463, the 75 year-old test bed locomotive for CSR's Project 130
You might think that a coal-burning locomotive built in 1937 had nothing left to offer the modern rail industry, short of being a nice museum piece. In the case of Locomotive 3463, however, that appears to be far from true – now in the hands of engineers from the Coalition for Sustainable Rail (CSR), it is set to become the world’s first carbon-neutral higher-speed locomotive. It won’t be electric, however. Instead, it will run on steam generated by the burning of biocoal.
