As soon as next year, voters could approve a passenger rail line that would extend along the Front Range from Pueblo and Colorado Springs to Boulder and Fort Collins, with other stops along the way.

• In 2010, a study determined that high-speed rail is feasible along both the I-70 and I-25 corridors
• Speeds would need to reach 90 mph or more to attract riders, according to the Rocky Mountain Rail Authority’s report
• A new study, announced Tuesday, will build on earlier reports, including the high-speed rail study
• The Obama administration had earmarked billions in funding for a potential high-speed rail network in the region
• That funding is no longer available under the current administration in Washington
• The new study will consider high-speed rail, but given voters’ recent rejection of funding for other transportation projects, slower, lower-cost technologies that do not reach 90 mph are likely to be recommended
• The state legislature could consider the new study’s recommendations as soon as this winter and put the new rail line on the 2020 ballot 
• Only voters along the Front Range would be asked to consider the proposition
