Eh no. They are Glasgow based staff that work the Glasgow services and sometimes return on an Edinburgh terminating train. The only staff who travel by taxi are the driver for the Glasgow services. There are no Glasgow based drivers. They are Edinburgh based and travel back to Edinburgh by taxi after arriving at night. They also travel to Glasgow by taxi to drive the morning train. Whilst not very good use of a driver's time that is how the trains are manned and worked. It would therefore make a lot more sense to have Glasgow based drivers too.
You are completely mistaken.
LNER do not, and trust me I know, do not have any Glasgow based crews. They are based at Edinburgh.
If there are ‘Glasgow based’ crew as you say, you’d better let LNER know as to there knowledge they don’t have a crew base at Glasgow!
