Railroad Pass gets its name from its potential as a possible route for a railway through the Coast Mountains although no formal record of such a survey exists.
[1] The Canadian Pacific Survey went through this area, but records only exist of survey parties attempting Ring Pass, at the head of the Lillooet River, and the divide between Meager Creek and Toba Inlet, as well as the southerly route since used by the Pacific Great Eastern, now a part of the Canadian National Railway conglomerate.
Railroad Pass was investigated in the 1980s as a possible extension route for BC Highway 99 as a "back door" for the Whistler resort in case of geotechnical emergencies that would isolate the resort (a more southerly route used by Cayoosh Pass was chosen).
A group of peaks on the north side of the pass is called the Railroad Group and includes summit-names like Locomotive Mountain, Tender, Caboose, and Handcar Peak.
