The BN SD40-2 #7149 was a natural gas locomotive developed for the Burlington Northern by Energy Conversions Inc. The successful demonstration locomotive operated on a commercial coal haul between Wyoming and Wisconsin from 1991-1996. The engine took the idea of natural gas rail out of the concept phase and into reality, proving the reliability, safety, and full-power capabilities of the clean burning ECI system.
Since the program's close in 1996, BN #7149 was sold to Helm Leasing and is now HLCX #7149. She is now normally powered but still wears ex-BN paint.
BNSF #7890, Which is HLCX 7149's mate, BN #7890 has gone onto to be placed within Burlington Northern Santa Fe's Diesel Roster as BNSF #7890, and currently wears the Heritage I paint scheme.
