Maryhill also provides two useful electrified diversionary routes. It means a useful service can be maintained on a big chunk of the North Clyde network during maintenance or enhancements between Hyndland and Partick, and electrified EGIP services would be able to run around the loop as they did during the summer of 2016. The former would be reasonably easy to sort out with sufficient notice, as you just need to train up North Clyde drivers on Westerton-Queen Street and take over the current Anniesland path. The other redirection isn't so likely to happen in the short term as Queen Street to Cowlairs was pretty comprehensively refurbished during the closure, but there may be occasions when it's worthwhile.
