I don't think Staff have looked into the possibility of having the train serve the Train Yards retail area, but it could be done.
The preferred location for the LRT Maintenance Facility is marked with fuchsia. This will probably be the chosen location since the competition is between here (St. Laurent), Bayview, and Hurdman North; and I don't think the other two will be acceptable. Assuming this location, a rail spur is required to get the trains to the West-East (W-E) Track. It is most likely that the spur will be run beside the VIA track and up the Hydro Corridor beside Belfast, as shown in red above. This extra length of rail offers no benefit to the riders.
Moving the W-E Track south of 'Alphabet Village' (Eastview Gardens) would put the track right beside the LRT Maintenance Facility and give the Train Yards retail area train access. Remember that the Train Yards has enough zoning for potential ridership of about 10,000 office workers, plus about 3,500 retail clerks, plus all of the shoppers. (OK, the train will probably not carry ALL of the people who go to the Train Yards area but potentially there could be a large number of passengers destined for here.)
There is also the possibility of adding an extra station to service the Tremblay Land. If the Feds are going to create another Tunneys Pasture there, the ridership potential could be huge.
The VIA Station would be services by a tunnel under the tracks.
OK, and here is the kicker - If the train is moved south to service the Train Yards retail area, then the bus priority along Innes, Industrial, and Terminal wouldn't be needed at all, thus saving an estimated $150M and not putting more buses onto already busy roads.
