Perhaps I am being too cynical; I guess we will see tomorrow!
I still think getting twice as many LRVs equipped with the specialized equipment in a quarter of the time seems unlikely.
I don’t think the simulated service test is going to be that easy to pass. Much like the burn-in test it isn’t just a box to check that the test was done; there are standards to be achieve and if the standard isn’t met the test has to be repeated from the start until it is. So if there is any kind of vehicle impairment the 600km burn-in has to be repeated until the test is passed without any impairments.
The Demonstrated System Operation (simulated service) test is the same. They need to operate the system with an availability of 92.00% (DSSPF = (Actual Train in Service Points/Scheduled Train in Service Points)) over a five-day period or they need to keep doing the simulated service test until that is achieved. The point violations are extremely specific (e.g. leaving 15 seconds early to 1 minute late gets earns a full point, depart more than 30 seconds earlier and you lose the whole point – interestingly though you can leave up to 4.5 mintues to the number of minutes of the currently scheduled headway and still earn 0.7 of the point, you have to leave more than the current headway’s time to lose the entire point). Same on the arrival side of the ledger. Arrive more than 1.5 minutes early earns no points, but arriving 1 minute early to up to 3 minutes late earns you the full point.
So they could do 5 days of testing and only get 91.99% and have to do another 5 days of testing.
“This demonstration shall be called the "Demonstrated System Operation – Stage 1 LRT System" and shall involve day-to-day operation of the System in accordance with the Region-approved System Operations Plan. During the DSO, the System shall be operated continuously (without interruption), as though in passenger service (without passengers), in strict accordance with all operations and maintenance policies and procedures, until the System Service Availability specified in the Schedule 15-3 Article 3 Section 3.6 has been achieved over a consecutive 5-day operating period.”

Everyone move to the back of the bus and we all get home faster.
