According to Bloomberg the Class 1s and GE / Cat are getting serious about converting some engines to LNG.  Are you guys hearing any of this stuff?

If a bit gets spilled would you have to clean it up?  Du?  Maybe a big bang tho.  hmm

The BN actually ran a few SD 40-2 sets of LNG units back in the late 1980s, and early 1990s... Two units, with a tank sandwich style between 'em.

The gas was the main fuel, and diesel was injected very, very sparingly ta provide a 'spark' ta light off the gas.
If memory serves, the sets were retired without changing a damn thing. And the results, lost ta history, although BN ran the shit outa that set all over the Northwest Division!

The experiments with gas-fuel may be done cooperatively this time. With railroads, and GE, and EMD/CAT doing the work. If LNG spills...it usually evaporates quickly because it only exists as a liquid as long as it's under pressure, and kept at extremely low temperatures.

 I remember those tests.  The word I heard around here was that they first tested them on coal trains, and that the Northern States Power was extremely pissed the first time those engines and their tender showed up at a coal fired plant.  Someting along the lines of "Get that mobile atomic bomb off of our property and don"t ever bring it back again!"

 

BucketHead, maybe some old heads from your territory remember this and could enlighten us?
