Best Answer

Most propane tanks located along railroad rights-of-way are there to supply fuel for "switch heaters" that prevent track switches from icing up or filling up with snow. You will usually find them near junctions, railroad crossings with other railroads, or "crossovers" where the trains can switch from one track to another. They are also used occasionally to power electric generators to keep signals operating during an extended power failure.
