Is the 3rd platform at Lougheed a $10 Million parking garage then?

The absence of a 3rd platform at Columbia is why the more logical routing - VCC to Columbia (reversing at Columbia to allow more trains to go to Surrey) - cannot be implemented. It takes too much time and is too disruptive to reverse a train in the middle of a mainline. The third platform at Lougheed would have been intended to address distant future capacity concerns at the Lougheed hub with all of the train movements contemplated.

Seems like they anticipate large volumes of passengers, so did not want one centre platform for both major destinations.
