Black Mesa & Lake Powell (BLKM) was built in the early 1970's for the sole purpose of transporting coal from the Peabody Coal Company's Black Mesa Mine near Kayenta, AZ, to the Navajo Generating Station power plant at Page, AZ. Coal is mined at the top of the mesa, takes an 8-10 mile conveyor belt trip to the loading silo's, then 78 rail miles to Page. Their sole trainset usually makes 3 round trips a day from the mine to Page and is electrified via the 50,000 volt overhead catenary.
