The drip, drip, drip of posts on this thread is what I objected to - not your individual post. I do think this topic has been beaten to death and people coming back to it virtually daily is getting annoying, to me anyways.
But think about this. Clearly the current service plan does not need these additional cars, and keeping them out of the mix just keeps the workload and costs down. However - clearly a change to the service plan will bring them into demand en masse. One hypothetical possibility about what would bring all these cars into play at once is more frequent service on the Kitchener line, which is approaching readiness for more trains to Bramalea. A second would be 15 minute service on LSE/LSW - which would double the number of cabs and locos required on that route. I discount Barrie or Stouffville as the tracks aren't ready for that. I also discount singe peak train increases, as there is likely enough slack in the fleet already for onesies or twosies.
We are not hearing about any such changes happening soon..... but.... Oncorr is coming. So maybe patience is necessary.
