I rode the new Line 5 Crosstown today, although only two stops¹. It was okay and there weren't that many people on it, which is good because the two-car "trains" don't look like they have a huge capacity. The actual transit was fine, the Cedarvale interface is a confusing mess, and I wish the trains came more frequently. Given wait times it's probably faster for me to walk to Cedarvale; I normally hit Eglinton midway between Fairbank & Oakwood stations.
