Interesting. Do you know much about Montreal's metro. For Toronto what is the proportion of open cut to covered? I was led to believe by someone who should know better that it was all underground! This may explain the reluctance to accept they are not on the right track: https://www.brainyquote.com/quotes/upton_sinclair_138285 https://www.brainyquote.com/quotes/upton_sinclair_138285

Calvin, I know little about Montreal. They use rubber tires and I have only ridden it twice, it is quieter than steel on turns. It may be dirtier? These wikis will give you most of what you want. Below Bloor Street it is fully underground. North of there a mixed bag - open where there was ravine land, underground where the cost to buy houses was excessive. https://en.wikipedia.org/wiki/Montreal_Metro https://en.wikipedia.org/wiki/Montreal_Metro https://en.wikipedia.org/wiki/Toronto_subway https://en.wikipedia.org/wiki/Toronto_subway Yes, As Sinclair intimates - conflict occurs = breakfast, lunch and dinner....

Calvin. The city owned the streets and ravines, so any route that used an existing ravine allowed for a surface rail segment. Under streets there was zero land cost, just the dig and shaft cost through the clay, garavel and hardpan that underlies Toronto. Going under houses was possible with forced purchase via eminent domain of the underground rights - but had a cost as tunneling cost more than cut and cover in these early days. We now have integrated tunneling/lining machines, so that is what they do not as C&C has large infrastructure relocation costs, whereas deep tunnels encounter only whatever is there. They extract drill cores on the planned routes these days to bypass any aquifers(wetted sand/gravel etc). The large east west light rail transport (LRT) used a combination of tunneling and surface/ravine open cuts. https://en.wikipedia.org/wiki/Line_5_Eglinton https://en.wikipedia.org/wiki/Line_5_Eglinton https://en.wikipedia.org/wiki/Jane_LRT https://en.wikipedia.org/wiki/Jane_LRT As you can see by the timeline, it was all fits and stops
