I just keep coming back to how closely that $128M for Cooksville would come to adding a third track to connect the existing triple track segments between Dixie and Mississauga. Especially if it, plus improvements between West Toronto and Strachan (which are roughed in, so the costly parts are already complete), allowed a couple of turnback trains to Erindale during peak service. Run a couple of trains express from Erindale, interleaved with the turnbacks - similar to express service from Bramalea. At $45M per trainset, the capital savings from equipment utilisation plus the $128M might do the job.
Of course, I am presuming CP would agree, and that’s a big ‘if’ .... my point is just that $128M on a prettier station is not building ridership nor is it addressing fundamental prerequisites for the RER vision.
