The monstrosity is an approximation of my understanding of its future look, in which it would become a big center for South Shore buses and trains to the airport as well as the metro. The ramp would be required because the space is too cramped so authorities are going to build a ramp to the empty lot south of the station.
The fuglifying vista-obliterating expansion would never have been necessary had the new Forum never been built adjacent to the train station.
Many Montrealers - including Phyllis Bronfman and Dinu Bumbaru - like this ramp-based initiative in spite of the fact that it would wreck the beauty of the stately old station.
What does Mike Fish, the sharp-tack father of local conservationism and longtime defender of Windsor station recommend? He suggests the Bell Center be demolished and the old Forum at Atwater be refurbished and host its arena functions anew. Fish points out that the process required to adapt the train tracks to the new Windsor Station project is prohibitively expensive and simply expanding into the Bell Center would be far more cost effective. I could offer more details of his critique if others wish to read.
