Actually, I added in $15M each for 7 stations; about one per Km. A total of $105M. I know you estimated $20M per station, but I was hopefull to build them a bit cheaper. Also I didn't know how many stations you added.

Do we then need to add $55M/Km for adding the rail, electrical, and ventilation to the tunnel?...

Hmmm. The MRC/Delcan number for conversion of the Transitway, including removal of asphalt, was about $12M. I added $3M/Km for utility relocations to bring the estimate up to $15M/Km. You might be right, however, and that might still not be enough. It might need to be $20M/Km. I don’t have a good ‘feel’ for what would need to be moved. I am kind of assuming that the rail could run along the median and where central turn lanes were needed, the road would be widened. I don’t know how much remaining capacity there is in the ROW for widening Carling, so it might even require some land acquisition.

I had already gone back to your previous post about your paper

and read through it. You mentioned that, without any suburban busway extensions, your route pulled in a 28% modal share. That tells me that you jumped up by over 8% from new riders along that one route. I think that is a good return since it is from within the Greenbelt where ridership is a bit lower during rush-hours. And your study only dealt with the AM PEAK. I would suggest that a Carling line would also generate higher ridership during the off-peak times. Is there any way to tell, from your modelling, where the extra riders came from; Carling or Montreal Rd. or split between the two?
My guess is that just converting the existing Bus Transitway to rail would not pick up substantially more riders. (Assuming no suburban extensions.) So the increase you noted would be almost entirely due to the new routing.
If the existing Bus Transitway was extended into the suburbs, as Option 4 suggests but without the western part's conversion to rail, and a rail line was added along Carling, what do you think the ridership share would be?
Based on the MRC/Delcan estimate for the Dows Lake tunnel, they estimate about $26.5M/Km for cut and cover tunnel. I rounded that up to $30M/Km. I also added the $55M/Km that they estimated to get a long tunnel train ready. I assume that this figure would include all the rail, electrical, ventilation, etc.. Then I added $15M for each of 7 stations along the 7 Km length. Since there is already a LF station I wouldn’t think that it will need the entire $15M so it could share with the Carling station. We might also find that large organizations, such as Carlingwood, would help finance their stations. So my estimate for a tunnel along Carling from LF to the O-Train would be about $700M.
Contrast this with the Option 4 cost for the section between Bayview and Baseline to be converted to rail. (Which I would suggest stays as bus.) The MRC/Delcan estimate for the Bayview-Baseline stretch is $158M. So the incremental cost to tunnel Carling is about $540M.
Another benefit of this idea is that nothing changes along the Ottawa Parkway. That is, nothing EXCEPT a possible reduction of buses. It might be possible to only run Express Buses along the Parkway only to supplement the rush-hour service: The Carling route might be able to handle the daily traffic.
But, I can hear you say, “What about the Councilors who want a train running into their subdivision?” Well, the train could be extended from LF, as per Option 4, to Kanata and Barrhaven. There is also the possibility of running a train from Barrhaven to downtown along the existing VIA track, past Merivale, and onto the O-Train track (which would be my preferred route).
