some dedicated and some shared track using positive train control technology. Intended to relieve
highway and, to some extent, air travel capacity constraints.
• Emerging HSR: Developing corridors of 100–500 miles, with strong potential for future HSR
regional and/or express service. Top speeds of up to 90–110 mph on primarily shared track
eventually using positive train control technology, with advanced grade crossing protection or
separation. Intended to develop the passenger rail market, and provide some relief to other modes.
• Conventional Rail: Traditional intercity passenger rail service of more than 100 miles with as few
as one to as many as 7–12 daily frequencies; may or may not have strong potential for future HSR
service. Top speeds of 79 mph to 90 mph generally on shared track. It is intended to provide travel
options and to develop the passenger rail market.
The above definitions evaluate HSR design potential based on population centers and achievable
speeds.
Today, the study corridor is described as a conventional and aged rail line that requires many
improvements to operate HSR passenger service. As shown in the 2009 population map, Figure 3-2, the
study corridor contains city population concentrations within travel distances desired for HSR. The
study corridor, is best described as an emerging HSR, especially since the corridor length is
approximately 100 miles and design speeds are between 90 -110 mph.
