With the question of shunts and axle counts, if the government has to authorize more money to do one or the other, by how much of a difference would one be worth doing over the other?
Why don't we do both? Say you live at one station that is only served by one direction, how do you get to it going the opposite way? Is that way really a good answer?
I am looking at low cost solutions that require very little closure of the area. It would be a couple of hours to post signs. Then it is just having them out there. What you are talking is weeks of construction closing the line.
Enforcement of the laws seems to be a bigger issues these days, not just for a transit mall. Simple as cops sitting along the street and handing out tickets during rush hour would go a long way. Not warnings either. A ticket. Then they can either fight it or pay it and learn.
Because of how close that corner is, that corner can be tighter. Hence the idea of slowing only for the corner and keep slowing down as they enter Union Station. That corner is only 2.5km from the station. If we assume a 45 mph corner, in those 2.5km,you are going to be slowing down to 0 mph...
Instead of a tunnel, is there any reason that from around Bloor that it becomes elevated? It then stays elevated right to the station. That could mean it is above the existing Union tracks and not bound to the mess that currently exists. Would it be cheaper? Would it solve many of the issues...
What if in at least the central core, the streetcar lines were in reserved lanes,without any additional infrastructure?
Keep the streets open for traffic, but no parking or stopping. And, at lights, no left turns?
It would be easy to do and simple for drivers to understand. And be easy to enforce.
The problem, especially with CPKC is they are very busy and adding slots would be challenging for them, With enough money, anything is possible. The question would really be how much?
