Railway Technology has covered several significant deals focusing on moving towards sustainable and eco-friendly transportation solutions in the railway industry. California State Transportation Agency and CalTrans have agreed to enhance their hydrogen-powered fleet by adding six more Stadler trains. This expansion demonstrates a serious commitment to deploying innovative and sustainable transport options. In South Korea, the city of Daejeon has selected Hyundai Rotem's hydrogen-powered rolling stock for its Urban Railway Line 2, showcasing the adoption of hydrogen fuel cells for public transportation. The availability of hydrogen is a crucial aspect of the industry's future, with the German national railway DB partnering with Lhyfe to supply green hydrogen for the DB H2goesRail project. This collaboration with Siemens Mobility highlights the importance of clean fuel sources in rail operations. In the US, Canadian Pacific Kansas City railroad and ATCO EnPower are collaborating to build hydrogen production and refuelling stations in Alberta, Canada, marking a significant step towards incorporating hydrogen as a fuel source for commercial transportation. Additionally, advancements in battery-electric trains, such as Stadler's BEMU technology, are gaining traction. Metra in Chicago and Massachusetts Bay Transportation Authority in Boston have invested in these green technologies to modernize their fleets and move towards fully electrified metro rail networks.
