That's interesting, Chak. Like some articles suggest, I think we will see the use of natural gas on a much larger scale in the near future. Some years ago a western railroad experimented with it in a couple of their small switch engines, but abandoned the idea because it didn't provide sufficient lubrication in the cylinders. There is probably an additive that has solved that issue. Cummins would know.
