| Comment | Get your point about 4 tracking being necessary once the tunnel joins the lines coming out of Queen St. Cost of this entire tunnel project would be so large though that the extra tracking would be factored in and seem kinda small change by comparison.
But you wouldn't need extra tracks beyond the big junction at Cowlairs. The track splits West, North and East there, with the different services going their own way. Also, the point is to absorb much of the rest of Scotland traffic that currently goes along those lines to Queen Street anyway. It'd just be sliding onto this tunnel track instead of going to Queen St. So you wouldnt necessarily have increased traffic on the section towards Croy than there already is. |
