gauge railways became the dominant narrow gauge throughout the United States from the Boston, Revere Beach and Lynn Railroad of Massachusetts to the Pacific Coast Railway of California. The gauge was also used by the Oahu Railway and Land Company of Hawaii, the White Pass and Yukon Route of Alaska and the dormant East Broad Top Railroad of Pennsylvania. Heritage railroads operate portions of the formerly extensive Colorado system as the Durango and Silverton Narrow Gauge Railroad and Cumbres and Toltec Scenic Railroad.
