Where are you getting this "triple branched line" thing from? Definitely not from what I wrote before.
From the Downtown tunnel heading west and branching at Bayview, there'd be:
1. to Westboro, Bayshore, Kanata
2. to Confederation Heights, Nepean, Barrhaven
From the Downtown tunnel heading east and branching at Hurdman, there'd be:
3. to St. Laurent, Gloucester, Orleans
4. to Confederation Heights, Greenboro, Airport/Riverside South
That's a double branched system, not triple.

The cost of triple branches is also going to be excessive. We have to build out in too many directions. We are seeing that a short branch to the airport alone will cost $155M and that is single tracked without electrification. How much will it cost to build the track from Confederation Heights to Barrhaven? $1B? more?

Less than the cost of building from Lincoln Fields to Barrhaven, because the existing tracks can be used for construction material delivery. For instance, instead of welding 40' sections of track together on site, we 400 yd sections of track delivered exactly where needed.

And then there are all the considerations of VIA Rail, who are not going to want to share track when they are trying to add service and speed up trains.

Well add the two extra tracks to the corridor, just like many other cities have done for their LRT systems. Most other cities love to use railway RoWs for LRT because it makes everything easier, but the busway mentality so dominates thinking here - including, bizarrely, someone who terms himself "lrt's friend" - that every contrived excuse is conjured up not to use them.

Of course, you are also right that corridor from Confederation Heights to Barrhaven is much too low density with too little potential to really justify building track all that distance with the hope of generating passengers almost entirely at the few stations at the end of the line. I would rather invest money on a cross-town DMU service on existing track that may actually get more people to leave their cars at home.

And just how much extra passengers do you think you're going to get on the Lincoln Fields to Barrhaven run of the current plan? The Woodroffe Ave corridor has precious little south of Baseline and lots of costs (notably Knoxdale to Hunt Club). At least the diagonal of the VIA corridor cuts across Merivale and Prince of Wales, allowing feeder buses from eastern Barrhaven to intersect the rapid transit line rather than "back track" to Fallowfield.

There was logic to the old N-S route which offered service to both Riverside South and Barrhaven. It built the minimum amount of track to service both communities.
|
That is absolute rubbish, and you know it because we've been through this countless times. It didn't even cut a straight line through Riverside South or Barrhaven, so how one can argue it builds the minimum amount of track with a straight face is beyond me.
The VIA corridor cuts across at a diagonal. Both the current BRT routing by way of Lincoln Fields and the N-S LRT by way of Riverside South go around two sides of a triangle compared to the more hypotenuse-like route of the VIA corridor.
