Just wanted to share my experience from riding Line 6 east at 17:45 on Saturday December 20. I rode the full eastbound service and the service was significantly improved versus opening day.
I observed the driver operating the vehicle more comfortably than before, with the vehicle reaching the full speed limit of 50-60 between intersections. Additionally, the driver slowed to just 30-35 at intersections and sped up after the front of the vehicle passed the halfway point of the intersection (technically violating the 25 km/h policy). The vehicle operated ahead of schedule for most of the route and observations show the schedule is extremely padded off-peak.
I recorded the stop arrival and departure times versus the scheduled times as well as light dwells and schedule padding holds.

| Total runtime | 0:41 | | | | |
| Total light dwell | 0:11 | | | | |
| Total schedule dwell | 0:04 | | | | |
| | | | | |
| Actual runtime | 0:26 | | | | |
Total end-to-end running time was about 40 mins 30 seconds, even with a 4 min hold from transit control at Mount Olive station and 11 mins worth of red lights.
This trip has improved my confidence in the performance of Line 6 and I think the design is actually fine. You could shave about 11 mins and 1 min off the running time if the city is able to revise the signal programming to permit aggressive TSP and from raised speed limits respectively, plus the 4 mins of schedule dwell giving a possible off-peak running time of 25 mins. I'd say during peak periods you could add 5 mins to that for heavier customer loading and traffic patterns.
This would raise the average speed of Line 6 to 25 km/h during off-peak and 21km/h during peak, which is respectable for light rail. More importantly, it would improve the speed of the LRT to be faster than the bus during almost all periods (except for late evenings).
Unfortunately some aspects of the speed cannot be improved such as during the curves between Humber College and Westmore, between Albion and Mount Olive, and between Sentinel and Finch West. The Alstom Citadis Spirit vehicles seem to not be able to handle curves of any sort and make terrible noises even when going at reduced speeds around them. Ironically, the Flexity Outlooks seem to handle curves in the track with much better comfort and performance.
