I would think they could get 600km of testing in in less than 6 months, but I'm not doing any math.
It's not just the vehicle break-in they need to do in that 6 months. They have to do testing on the yet to be implemented ATP system and cab signals. as well as the grade crossings from Mill to Fairway and the traffic signals as well. They need all 14 here to do the ATP and cab signal part as it's the most complex and needs to be tuned for the proper headways with the vehicles.
The ATP system can be tested without all the vehicles. In fact, everything can be tested without all the vehicles, except for each specific remaining vehicle — obviously they can’t test the cab signals in 510 without 510 on property. Previously they indicated that 3 vehicles were enough to test the system as a whole, and this makes sense because one could run the 3 vehicles through the line, maintaining headway, and thereby test all the signalling, scheduling, and whatever else there is.
Also I should point out that with 7 minute minimum headway, there is no interaction between vehicles under normal circumstances. The only time you should see 2 vehicles near each other is in the OMSF and when two opposite-direction vehicles pass each other. So headway management etc. can be done with a sheet of paper printed with the schedule in each vehicle. It doesn’t matter whether any related automated systems are working, other than safety signalling. This is not downtown Toronto or New York.
As far as I’m concerned, the system should open about 2 weeks after vehicle 12 gets here, on the assumption that 13 and 14 are “on the way” and will be present well before there is likely to be a need to withdraw one of 1-12 from service for any reason.
Any schedule slower than this does not qualify as “aggressive”. “Aggressive” would mean crews out every day doing stuff, not this sort of interminable dribble of work happening once in a while.
