One of the barriers to widespread use of CNG is that its energy density is 1/4 that of diesel for a given tank volume. Locomotive diesel users such as BNSF are looking at using LNG, which has a higher energy density than CNG plus they can pull a load of LNG in a tender car. Another large railroad user is Union Pacific, which burned 1 billion gallons of diesel last year at an average cost of $3.22/gal. There will be a rush of railroads to climb on the natural gas bandwagon.
