The North/South O-Train line could be extended from Confederation station, along the OCR right of way to Kanata.
This is a long extension, and would have stations in Kanata (March Rd), at Herzberg Rd, the Queensway Carleton Hospital/Bells Corners, as well as stations at Woodroffe, Merivale and Colonnade.
A person boarding at Kanata would have 30 minute service to Bayview, with transfers to the downtown eLRT, or possible extension to Gatineau.
This extension would be done with diesel LRT vehicles.
This extension has not yet been priced in detail, but should cost less than $41M.
The train from Kanata could be extended from Confederation through Billings to Hurdman using the VIA line, rather than to Bayview.
Such an extension might provide for 1-transfer service between Orleans and Kanata, avoiding downtown. (This trip would take approx. 45-50 minutes from Place d'Orleans to March Road by bus and train, compared to 1 hour 18 minutes by bus today).
