The REM is pretty sweet, the only down side is the bus system getting to it in the suburbs is a bit shambolic. Driving to the station takes 7 minutes, but parking is full by 6:30, while the most direct bus takes over half an hour!
Make the parking lot bigger. Then give the parking lot its own small railcar system for getting to the station. Expand. Recurse. Fractal transit.
Biking there should not take very long if it's only a 7 minute drive
the parking is free so of course it's quite popular. Having been there regularly on the busiest weekdays you really have to arrive close to 8:00 to see a full lot. I do agree the REM is sweet and very effective.
