Model trains in the news.......I thought it was going to have something to do with harnessing "natural gas" from animals or the byproduct produced from them.

Cool, one of those babies crash there will be a big boom.
Maybe they should install ejection seats?

Doesn't the train need to carry a much larger volume of gas than it does diesel to get from point A to point B? I'm thinking that any gain from using lng over diesel would be offset by the weight of hauling the amount of lng needed to keep the train running.

Go figure...

1 Gallon of LNG weighs 3.84 Lbs and has 89,000 BTU's

1 Gallon of Diesel weighs 7.076 Lbs and has 136,533 BTU's

LNG weighs 54% the weight of Diesel

LNG has 65% of the BTU's of diesel

LNG has 23,200 BTU's per pound

Diesel has 19,300 BTU's per pound

Te fuel tank would need to be 35% larger and much thicker (Pressure vessel)
to contain the LNG.

The question is what is the difference in hydrocarbons emissions of the two fuels.

I would guess that the natural gas would be lower in emissions, at least that's the claim for oil fired vs gas fired furnaces and power plants.

All the locomotive would need is a tender that is a tanker to supply the gas.

Is that what that picture is Jack? The tanker behind it is to fuel the locomotive?
