The W line is a train with a half dozen stops in single family neighborhoods, which means there are few customers and it goes really slowly from one end to the other. It's no wonder the line is failing, the communities along the route are doing everything hey can to ensure it.

Either remove the empty stops so you can at least get from Golden to Union Station in a reasonable amount of time or re-zone everything within a half mile of each stop for dense, mixed use development. Option two has the bonus add-on effect of lowering housing costs but is widely opposed by those single family homeowners who think that they should get their own private train station.
