And in Toronto's case, the BD line is considered under capacity by comparison with Yonge.

I believe that this is not quite accurate. Per Wikipedia, which I concede is an imperfect source,
the T-Series cars used on the Bloor-Danforth line are 75' 5 1/2" long and 10' 3 5/8" wide; I don't know the specific dimensions of the M4 cars used on the Market-Frankford Subway Elevated, but I know that they are about 55' long and narrower than the T-Series cars, so a six-car M4 train is about 330' feet long, which is the constraint of the line's platform lengths, whereas a T-Series train of that length would be 450' long, so the MFSE probably has something like 3/5th of the capacity per train of the Bloor-Danforth Line. Furthermore,
Bloor Danforth Line's frequency is 2-3 minutes at peak, where as the MFSE has 4-minute peak headways. A more compete, accurate analysis is beyond me, certainly at the moment, but the situation of the MFSE is probably slightly direr than the comparison might suggest.
The frequency is a relatively obvious, economical candidate for improvement; at its most expensive it would require a new signal system and new cars to replace the unreliable M4s. Nevertheless, the current, but soon to be former, General Manager's preferred and very stupid solution is to expand the platforms by 110' to accommodate 8-car trains, which page 7 of
the latest capital budget cites a cost of $ 1.3 billion for, although it would almost certainly end up higher if done and would be massively disruptive at the same time. I sincerely hope that his successor abandons the idea.
Regardless, the smaller cars, shorter platforms and availability of only two tracks makes the MFSE an inferior candidate for any branches compared to the Broad Street Subway, which has 67 1/2" cars, 550' platforms and four tracks from Olney to Walnut-Locust.
