I guess you could make the north central line an extension of the end of the current blue line line that crosses by the airport and comes back down Centre to 16th Street or even end at Eau Claire. That would make use of the existing red/blue facility. You'd have to do high floor though.

This should be phrased as without connecting the lines there is a capital and opex cost in building a second maintenance facility. There isn’t anything inherently wrong with having two, it’s just a cost.
Since the North Line is not being built in the underground model for 50 years the NPV of those savings are near 0. If you believe the North Central line gets built in 25 years the NPV is still near 0. If you believe the North central line is built within 10 years then the savings could be meaningful but we are talking 50% of capital savings and less of operating savings. Essentially because the cost savings are so far out into the future it likely shouldn’t be considered as a benefit.
