The only way I would go for an LRT DRL is if the line was four-tracked under Queen with the DRL running express and the Queen streetcar running local. Most other configurations with LRT simply would not have enough capacity to meet the projected demand. Just a DRL East from Danforth to Union is projected to carry 17,500 pphpd on opening. That's one 6-car LRT train every ~3 min. With that line extended north to Eglinton, it could see 25,000 pphpd easily. That's one 6-car LRT train every 2 minutes. But those numbers are completely irrelevant, because you can't run 6-car LRT trains in-median (which it would be north of Eglinton on either side). So they would either have to short-turn at the end of the tunnels, or they would have to run 3 car LRT trains every 1 min 6 sec in order to meet that demand. It's just not economical.
