It's true that they do not count for inflation, but they were constructed incrementally at about the same rate so it's a relatively moot point. If anything, it's makes the Transitway look better because the figure quoted is only up until 1996 whereas Calgary is to present day.

Combining a few posts... How did you simulate it? Do you have access to software? I'd be interested to look at your simulation. Why do you think Carling did so poorly?

I used the City's (actually the TRANS committee's) travel demand model in EMME. This model forms the basis for all transportation planning in the City. It was recently redeveloped to state-of-the-art standard and calibrated to the 2005 OD survey by a consulting firm in NYC. If you search the old thread, you'll find what I posted some time in late April or early May.
I suspect the reason the Carling alignment did poorly was because of the extra distance and the forced transfer. Before you jump and say this is evidence that a bus based system is optimal: the model was configured such that the downtown portion was not capacity constrained.

Rail is 89% the cost of buses according to the study. 10% looks like a margin of error to me on these predicted costs.

50M$ is not a margin of error...especially when there are fixed costs to both that are the same regarless of option to water things down (ie. new transitway segments, etc.).
Using those numbers, I believe somebody calculated the payback period for the rail option to be in the area of 30 years.
Anyway, this is my final word on this topic. I've wasted far too much time on an argument that cannot be won by either side.
