Recently, the National Railway Administration has publicly solicited opinions on the "Administrative Provisions on the Retrofitting of Power Source Systems for Aging Railway Diesel Locomotives (Draft for Public Consultation)".
The document states that the retrofitting of power source systems for aging railway diesel locomotives involves replacing the fossil fuel power systems of aging railway diesel locomotives with power systems such as "diesel engine + power battery system", "power battery system", and "hydrogen fuel cell system + power battery system", which offer superior energy efficiency and emission levels. Locomotive owners should strengthen the operational safety management of power batteries, construct ground support facilities such as charging and hydrogen fuel refueling stations in accordance with relevant national standards, and recycle and dispose of power batteries in compliance with relevant national regulations.
