Since the second half of the 20th century, four-axle diesel-electric switcher locomotives have been used extensively on short lines. The most common are the EMD SW1500 (1,500 hp/1,119 kW), GP9 (1,750 hp/1,305
First, let’s look at the release of harmful substances by locomotives with onboard energy sources. The most prominent is the diesel-electric locomotive. Its electric traction motors are environmentally friendly, but its diesel
Hybrid technology combing hydrogen fuel cells (HFC) and batteries may be a viable means to obtain high power ratings for main line North American locomotives, which for a very long time have
U.S. regional/commuter trains traveling relatively short distances are making progress on ZE (zero emission) initiatives. The technology under evaluation comes from numerous global sources. For ZE long-distance trains, battery-electric and HFC (hydrogen
By 2050, in accordance with the Paris Climate Agreement, zero-emission locomotives may have completely replaced conventional diesel-powered equipment on the railways of the world. Current development of zero-emission switcher locomotives, combined with
RAILWAY AGE, AUGUST 2021 ISSUE: The GEVO12-equipped, three-section 3TE25K2M is among the world’s most powerful diesel-electric locomotives.
Based on emerging technologies in batteries, hydrogen fuel cells and renewable natural gas, zero-emission motive power is a possibility.
