This just further proves the greater overlap in abilities between HRVs and LRVs.


And yet, you conveniently ignore a stat in which an LRT system beats LA's heavy rail for frequency. Even within LA people subsequently have pointed out the C Line, an LRT line, is faster than all of LA's other lines, and all of the DC metro lines.

And tell me, if both LRT and HRT are grade-separated, how is that specifically contributing to greater frequency (which I've already debunked anyway)?

In terms of speed, the DART LRT runs at an average of 30 miles (48km) per hour while New York's HRT subway runs at an average of 17 miles (27km) per hour and Chicago's L has an average of 23 (37km) miles per hour.
So what exactly is your point about rolling stock vis-a-vis capacity? How does it represent a fundamental difference between "HRT" and "LRT" if some LRVs are wider than some of the HRVs running on three of the world's top 10 metro systems and LRT lines having the capacity to draw the same ridership as HRT lines?

You said the following:

The difference between HRT and LRT absolutely is rolling stock (which is how it has higher capacity more easily)
Does that mean BART is more of a HRT system than the Paris Metro?

As for frequency, LA's two "HRT" lines are limited to 4-minute headways because they interline between Union Station and Wilshire/Vermont. More to the point, frequency/headways and ridership are correlational, not causal. And ridership is not a reflection of capacity, but rather more locally specific factors such as the nature of the corridor itself, demand, quality of service, overall transit appetite, etc.

You're painting with a very broad brush and totally ignoring important physical, cultural, and logistical differences.
