The class 314's are in their final months of service as they will be withdrawn when sufficient class 385's are in service to allow them to be replaced. The is expected to be either later this year or into next year, so it is a case of ride them and photograph them while you can.
I've been in Glasgow at various times on Saturdays over the past 3 weeks but mainly in the morning and have noticed a pattern of workings during this time. I have shared my observations below for anyone who is looking to photo / ride on the units. Hopefully they are of some use!
Observations
There appears to be interworking between the Newton via Maxwell Park and circle services e.g. some of the time a unit coming off a Newton service goes on to do either an Inner or outer circle (or inner then outer or vice versa).
