TEM19-001 shunter with gas engine. The world's first locomotive to run on compressed natural gas.
The TEM19 was developed by the Russian Institute of Research, Design and Technological Studies (VNIKTI) and Transmashholding (TMH) subsidiary Bryansk Machine Building Plant (BMZ) as part of Russian Railways’ (RZD) energy strategy, which is seeking alternatives to diesel power for non-electrified lines. The use of natural gas power has the potential to reduce operating and life-cycle costs as well as making rail transport more environmentally-friendly.
The gaspiston locomotive is based on a modular design consisting of the following elements:
• driver’s cab
• cryogenic unit with gas preparation and LNG feeder systems
• motorgenerator set
• cooling system
• equipment chamber
• electrodynamic brake equipment module, and
• compressor unit.
A separate module contains secondary equipment deployed under the locomotive frame.
