I understand that the Red Line on paper is sort of different from light rail, but, like every curious and highly critical layman, I don't understand why it's not, since it obviously looks like light rail and CapMetro sort of wants you to treat it that way.
I get that every system has a blend of different modes, but I haven't heard from CapMetro why the Red Line is different, and can't connect. While you, a well-versed transit guy, knows the ins and outs, I, the aforementioned layman, do not, and need to be walked through what seems an obvious problem.
Who or what is FRA and FTA, and what is the difference, and why does it matter?

CapMetro has gradually inched towards some hybrid aspects, but the Red line is still overwhelmingly a commuter system.
The main distinguishing features are
1) service frequency and operating hours/days. Emphasis on peak vs. off-peak can make a difference here, though that was one of CM's first compromises.
2) station spacing. sometimes station manner of construction.
3) A little bit of direction of transit demand.
4) (kinda) geographic reach
1)The red line, in part due to sharing the tracks with freight, has pretty limited operating hours. The frequency is currently way down. The improvements that are in progress should bump it up a bit, but then it'll be ~15 minute peaks, not like 5-10 minute.
There's some Saturday service now, but not all day and none on Sunday.
CM even started with no mid day service, but added some.
2)The stations are broadly spaced, even in the urban core but especially in the suburbs. That'll vary in light rail systems towards the fringes, but not nearly to the extent of commuter rail. It's like 10 miles (a third of the line) from Leander to Lakeline. You'd never see that with electrified light rail, that would be like an extra billion dollars in construction costs.
You'll end up getting suburban focused stations towards the ends of light rail, but with the red line McNeil and further are park and rides. It's a minority of stations but the majority of the line. If Cedar Park was still in Capmetro, there probably would be at least one more P+R.
3) Even in light rail demand will be downtown focused, but the vast majority of the red line's ridership(like 90%) rides south and gets off at downtown in the morning then turns around and boards the downtown station in the evening.
This is one that may start to change eventually, if/when Broadmore (and Robinson in the future?) start to become more destinations in their own right.
4) Going 32 miles out isn't unheard of for light rail. But I think it would be for a single light rail line. Even DART (which is more suburban focused than most, I don't think started going that far out).
