Gweed also makes a good point I've neglected to mention. The RH SmartTrack trains would enter the downtown tunnel while the RH GO-RER trains would go to Union. That is another key reason for differentiating services.
The 'extra costs' of extending to Langstaff are present in any case because the RH corridor will need to be electrified and converted to RER at some point anyway. The more complicated Gerrard Square interchange is worth the extra dollars to create this kind of service.
I don't think you can compare this scheme with the reported numbers of relief by GO as this is not an apples-to-apples comparison. The utility and dynamics of the line completely changes to an electrified, rapid, subway-level-frequency corridor that goes directly to our CBD and destinations west and east of it rather than to Union, interchanging with Sheppard, Eglinton and Bloor-Danforth along the way. Nothing like the present RH-GO.
I am hoping it is distance-based. SmartTrack/GO-RER stations inside the 416 pay cheaper fare than in the 905.There's no reason to think that Smarttrack or the TTC in general will be any cheaper than GO over the same distances when fares are integrated.
The cost savings would be from not having to spend an exuberant amount of money on the repairs, Don flooding damages and realignment of the Richmond Hill corridor south of Lawrence, as we would be combining corridors with the DRL.If these plans are basically the DRL route (tunneled) south of Lawrence, then I don't understand how these plans are any cheaper than the Long Relief Line that they looked at in the report, which only went to Sheppard.
Sure, you are saving on tunneling costs by only tunneling south of Lawrence, but you are also adding significant costs by extending the line all the way to Langstaff. The Lawrence - Langstaff at-grade portion is probably 5 - 6 times longer than Lawrence to Sheppard along Don Mills. You also need to add in the cost of grade separation for the Doncaster Diamond, and a costlier station at Gerrard Square to support the switching service that is being described, as it needs to be able to simultaneously send trains downtown via tunnel and to Union at-grade via the rail corridor.
Yeah, I get that the idea is to provide a DRL as well as an improved RH GO line, but if you look at the numbers in the Metrolinx relief study, it is pretty clear that the few passengers who take RH GO hardly matter (and would be better served by GO RER), and that the bulk of the ridership is being redirected from Yonge (ie. coming from points east).
