" where is the Colo Blvd line? Where is the Colfax train? Where is the Broadway train? Where's the Speer Blvd. Line?"
Agree on this. 
Our rail lines have been built where it was easy to build, not where there was high demand. Now we have to wait for development around them. 
We should be upgrading transit lines that already have high demand. Colfax BRT is a step in the right direction.
