I suspected as much, perhaps something like Dumbarton - Queen Street low level - Springburn - Anniesland?
You'd have to build the E&G flyover at Cowlairs which would only be justified if you wanted to remove all North Suburban services from Queen St High Level in order to free up capacity for longer distance services. I don't suppose the residents of Maryhill would be too happy about going the long way round to Queen St.
