About Wood, Coal Pellet Stoves. Pellet stoves are fueled by small "beads" of compressed wood and other plant materials. They are believed to produce a hotter, more efficient heat than wood, but the efficiency comes with a higher price tag. And while pellet fuel tends to be more costly, the pellet stoves themselves require less upkeep by relying on

Dec 12, 2018From what I have heard the coal mine was closed and the power plant was converted from coal to natural gas. The train was unique in the fact that it was all steel coal cars. Quite a rarity on the main line anymore. Sad to hear of this trains passing. Filmed this train many times on the Moffat route. Last time I saw this train was in July of 2017.
