With potentially 5 bus routes continuing to run along Sheppard, that photo might be recreated next decade even with the LRT (which could easily be bunched, too).
Density doesn't matter...riders do. With all that density in central places like the old city of Toronto, how do you explain Museum or Old Mill or Chester or Summerhill compared to Warden or Wilson? Is North York Centre or Yorkdale not dense enough? This forum should have a feature where the words "dense" and "density" are automatically replaced by "kittens" or "boobies" due to rampant misuse.
If budgets were unlimited why wouldn't someone propose 5000 km of subways instead of an obviously reasonable ballpark figure like 50km that would obviously get built over a large number of years and not instantaneously? Oh, that's right, nothing's obvious when you launch into rants without even reading what you're responding to.
If Transfer City funds could be transferred (and they can't, but that doesn't prevent 'what if?' past or future scenarios), yes, you would get dozens of km of subways, possibly over 50km if construction/design was controlled better (we're talking about theoreticals here, meaning not always tunnelling under grass or building 25-bay bus terminals). Trenched segments, shallow cut'n'cover segments, even some elevated portions...grade separated transit does not need to be that expensive.
And where is this "one sector" of the city that 50km of subway can hide in? Don't you realize how long 50km is and how many priority neighbourhoods that can hit? That could be a whole DRL, a whole Eglinton subway, an extension to STC, and leave a few km left over. Or any other combination. It'd only benefit several million people per day...how horrible and IMPOSSIBLE! The city would probably never even need 50km of subway...it's hard to justify that quantity once you factor in GO improvements.
Newsflash: future budget problems affect lines on the books, too. If 50km of subways is impossible (and it isn't), that means the DRL is impossible, the Jane LRT is impossible, etc. An important project like the DRL could have been underway instead of in the books and far from a sure thing in the next decade or more, if Miller had focused on it instead of, say, three light rail lines to Malvern. So much money is being sunk into Eglinton's ballooning budget that even the rest of your precious Transit City is suffering and may never be built. Hopefully, the next mayor won't make these sorts of miserable mistakes. If it means cutting back on multiple redundant lines to Malvern or cutting unaffordable lines like Jane that an astounding less than two thousand people per hour will use, then so be it...the city will benefit. At least with Miller gone, there'll be one less person screaming "subways are impossible!" even as blank cheques come and go and more money is spent on other projects.
