Unusually I was at King and Spadina at about 10 pm on Saturday. A couple of observations - the Spadina car heading east on King - presumably to Russell - didn't take passengers - at least it certainly didn't stop for me at Peter street, despite me standing at the stop waving.
Secondly, waiting for a northbound Spadina car. A 15-minute wait - probably longer, as I didn't see any pass while I was walking. And then the car was so packed that it took about 25 minutes to get from King to Spaina station.
Anyone who says next streetcar signs are a waste of time on these routes because they are too frequent, clearly doesn't actually use them. It would have been very useful to know when the next car was coming, as if I'd known I'd have been standing there for 15 minutes - which also then means the service is going to be very slow, I'd have caught a King car, or walked to the subway.
