the old rail is not worth the money. 
It makes sense to make social transportation available, but it makes ZERO sense to put something like twin rail in place when it is SOOO expensive, Slow, and ALWAYS NEEDING FUNDING. 
Look at the LRT by RTD. It is a joke. It should have been something elevated right from the gitgo, such as monorail, so that it was cheaper to not only put in, but to run. LRT is expensive all the way around.
