A few things reported elsewhere.
The Fort William portion didn't run on Thursday evening / Friday morning due to flooding on the West Highland Line. It appears that the sleeping coaches went to Aberdeen on Friday morning.
The Fort William portion then ran empty to Edinburgh on Friday night, and then to Polmadie so that
a) the 'day coaches' could go for servicing
b) the sleeping coaches could be coupled back to the Glasgow portion (which ran three coaches short from London on Friday night
I wonder whether some Glasgow passengers were turned away or reaccommodated due to the missing coaches.

Fort William day coaches

Friday night's sleepers
1M11 CS01+CS04
1M16 CS03+CS05
1S25 CS07+CS06
1S26 CS08+CS02 (15338-15326-15211 missing as they should have been in the Glasgow portion)
Most noticeable is that 15213 and 15214 appear to now be in use instead of 15208 and 15322 so CS02 is misformed with a 152xx vehicle in place of a 153xx vehicle.
