The area between the Twin Cities and St. Cloud is gaining population so fast it's one of the fastest growing places in the country. And while the growth brings new economic viability to many communities, it also means frustration for commuters. Transportation officials are looking for ways to alleviate the congestion. One solution they've suggested is an 80 mile train line linking the St. Cloud area with Minneapolis. Backers of the Northstar commuter rail line say the project is a bargain compared to building roads. But opponents say its nearly 300 (M) million dollar price tag is too expensive for the number of people who would actually use the train.
