Trivia: Greatest variation of passenger traction working a specific service

Paddington- Reading:

43
57
165
166
387
800
802

Having re-read the OP, I don’t think the Sleeper, HST & IETs count!

Wasn't one of the counter-peak workings (I think the 08:09/12 from Paddington to Reading) HST diagrammed?

Some of those I had no idea about. The original Swindon for example. But...

...but examples mainly must account for a period of up to a year, as opposed to the number of traction over the course of 150 years.

I've also been on doubled up 153s working the Cheltenham - Maesteg and they have also been used to add capacity to the 150s on the route

I didn''t include 153s to Maesteg as I quoted only booked workings. They are, as you say, seen quite often and quite often single ones work to Cheltenham.

Huddersfield to Leeds via Bradford Interchange (the train I catch most). So a true 'single service' in the spirit of the OP.

In the last 12 months I've had:
142
144
150
153
155
156
158

If you consider the BDI to Low Moor leg only, you can add 180s to that

Avocet Line in Devon (Exeter-Exmouth)
If you include SWR services to Salisbury/Waterloo you get classes 143, 150, 153, 158 and 159 (plus GWR diverts may also give the line HSTs and IETs)

Plymouth-Penzance:
class 150, class 153, class 158, class 255, class 802 and HSTs
