Diesel-to-natural gas locomotive conversion
Czero designed a novel Compressed Natural Gas (CNG) tender car system for diesel-electric locomotives. Specifically, we:
- Developed a containerized custom genset, with a Cummins QSK60 (1.5MW) engine, to supply electrical power fueled by a bank of CNG tanks
- Designed and analyzed the thermal management system
- Performed the complex systems integration and packaging of the custom genset and all the ancillary systems into a 30' ISO container
- Successfully operated the system in field tests with Bright Rail Energy (BRE)
