Utah Railway's Wildcat, UT to Moapa, NV coal load curves west along the location of Rio Grande's former Nolan (center) passing siding, about 10 miles west of Helper. Dual ABS signals 6351 & 6352 once protected the east end of the passing siding, but were later moved about a 1/4 mile to the west becoming new intermediates when the siding was removed and CTC with dual directional two main tracks was installed.
