Trivia: Highest mileage diagram in a day?

[Elecman]

I think that article is old now.
What I now have has split this into:

FIRST DIAGRAM FROM WEMBLEY
0422 ECS Wembley to Euston
0526 Liverpool Lime Street
0847 Euston
1130 Glasgow Central
1640 Euston
2333 ECS to Wembley

SECOND DIAGRAM FROM WEMBLEY
04:30 ECS Wembley to Euston
05:31 Glasgow Central
11:40 Euston
16:29 ECS Euston Carriage Shed
17:23 ECS Euston
17:40 Manchester Piccadilly
20:15 Euston
23:00 Manchester Piccadilly
02:22 ECS Longsight Depot

Worked out from RTT and OTT.​

Euston Carriage Shed? Do you mean Euston Downside sidings? The Carriage Shed has been closed for years and indeed is now cut off from the Network by HS2 enabling works

I think it's the Class 139 running the Stourbridge Town - Stourbridge Junction shuttle.

At a little over 1 and a half miles per round trip, it would need to do 645 round trips in a day to even break 1000 miles.

As it is the Stourbridge shuttle is by my count 107 round trips totalling 165mi 68ch - possibly one of the lowest daily mileage unit diagrams in he country!

And about the shortest run to its depot of any fleet!
