Also remember that the Class 314s were introduced in 1979, which coincided with the reopening of the section of the Glasgow Central Railway between Rutherglen and Finnieston, and were designed for that route.
Over time, the Class 314s have become the workhorses of the electrified routes around Glasgow - similar as how the Class 455s have become the workhorses of the local all stations services south of the mighty Thames.
In 2019, the Class 314s will have reached 40 years in service, which is the operational lifespan of what was intended. As they are seeing out their twilight years mainly on the Cathcart District Railway, and the remnants of the Lanarkshire & Ayrshire Railway between Neilston and Newton, combined with the route having been electrified in 1960 and due for replacement (as it will be 60 years in 2020 of the OHLE having been installed), maybe now is the time to consider the possibility of converting the CDR and Newton - Neilston to tram operation?
By converting to tram operation, a couple of slight deviations could be made from the original formation. The first one could deviate onto a new alignment between Pollokshields West and north of the mighty Clyde so as to serve West Street underground station, with the second deviation leaving at Whitecraigs to run along the main Ayr Road to Mearns Cross, then swing down Barrhead Road to Crookfur, then rejoin the original formation at Patterton.
On a final point, by converting a conventional rail route to tram operation, Glasgow would then be taking the lead from Sheffield, Manchester, Birmingham, Croydon, and Nottingham by bringing back trams to a large town or city in the proper manner. I am well aware Auld Reekie has a tram line, but I perceive that to be a New Labour vanity project that was not required at all, of which the Jack McConnell led government were not new at all, and were most certainly not Labour.
