Locomotive 73 is on track to travel 33% farther on CNG this year than it did in 2012, saving nearly $60,000.

The Wine Train’s 36-mile route from Napa to St. Helena follows tracks dating from 1864. The current operation commenced in September 1989. There are four Alco FA locomotives, built in Montreal in 1958-1959, and purchased from the Canadian National Railroad

Wine Train locomotive 73 now runs solely on natural gas, having been converted by Tacoma, Wash.-based Energy Conversions, Inc. (HHP Insight, September 13).
