^Yes, MetroLink will have a slower overall average speed on the North-South line. However, it will have extreme range from a crawl on downtown turns to 55 mph along the UPRR or I-55 sections. The average speed on today's MetroLink, despite mostly being exclusive-running, still only averages around 32 mph. While Busdad has complained that this "streetcar" might average as low as 13 mph, hence his "fancy bus" comment, street-running LRVs will easily average over 20 mph, albeit below current MetroLink's 32 mph.
A mostly street-running light-rail line will make up time through access management, reserved lanes/medians, signal prioritization and directness of routes, in addition to more exclusive ROW at the southern end. But even Goodfellow due to its width and limited intersections north of Natural Bridge will enable a faster median at the northern end. Essentially, trains will travel slower as they get closer to downtown or faster as they move away from downtown.
Likewise, stations will be spaced more frequently on slower sections, while spaced further apart on faster sections. Ironically, current Current MetroLink loses speed by pulling into and out of stations, adding as much time to the commute as the actual sitting dwell time at the platform. But hey, you do want full trains (riders from stations), not just fast trains (never stopping). Plus, if you're already traveling slower on Natural Bridge (and by law, trains can't exceed the posted speed for motorists), more stations don't hurt you street-running line's travel time as much as added stations do on an exclusive-running line.
