The Feds will be fine with it. Their narrative only depends on being able to say they are contributing funding to .... whatever is built. And all they want is the narrative, not the effective transit system.
The point
@reaperexpress made, and it's a real serious risk is.... a scenario where the value engineering exceeds prudent value-for-money design challenges (which is desirable) and becomes short-sighted engineering-in of constraints (that bite us later, when the politicians involved have all retired) just to save money. Or goes unnoticed.... if Durham Region fails to expand as well as it could, because the GO service is too slow or infrequent, will anyone actually notice until it's too late? The decision not to build the flyover at Scarborough, the scaling back of grade separation and triple tracking east of Guildwood, building two-track bridges without roughing in the width for a third track, the awkward track plan for the routing through Oshawa.... these all will have been "value engineered" but may be profoundly unwise.
And since all of this happens behind closed doors, and represents a level of thought and analysis that politicians and voters generally don't get....
