Not sure which day it was since I was last on the VLSE on Tuesday when all schools were still out, but, by today all trains are now 2 cars, increased from alternating 1 car/ 2 car trains we saw for the first week and into this week. I assume weekends will remain the 1/2 split. Wouldn't be surprised to see them even drop to single cars on Sunday's in the future, depending upon season and events.
One thing with the interaction with traffic signals for this line, if a train is late, you're getting stopped. I've been on, and observed a few trains now delayed out of Mill Woods (not "Millwoods"), even only by a minute which then meant getting stopped at 28 Ave, the Fire station, 31 Ave.
One interesting scenario I observed today, a train seemed delayed out of Mill Woods. The proceed signal for 28 Ave had been in place for quite some time. Upon approach, the proceed signal started to flash (like a flashing pedestrian signal) so the train started to slow down to stop. It however then went solid again so the train was able to carry on. That didn't help it at the fire station crossing though and it came to a stop there. So, it does seem that signals can be reset by an approaching train.
In another instance we were stopped at 34 Ave and after that we were stopped at every crossing until we were probably synced correctly at the Woodvale stop.
As a pedestrian, I was trying to cross 28 Ave at the Burger King crossing. I couldn't see it, but I knew a train was approaching as the pedestrian stop signal recycled to a go signal and the light for 28 Ave traffic stayed green. This was annoying as a pedestrian being stuck waiting the extra time. Surely we could have been given a walk signal. It's a quick light. 15 second countdown or so. Besides, it's not like the green light helps westbound traffic because the train is crossing 28 Ave half a block away, and because of that there's no eastbound traffic that can benefit from the green light.
