TRIVIA: Unit that has worked for the most TOCs

[adc82140]

Just thinking in an idle moment, which unit, current or past, has worked for the most number of different TOCs?

To clarify, this is an individual unit, not a class of unit
Also, successor TOCs don't count, so for example Anglia, One, NXEA and Greater Anglia wouldn't apply.

I'll start:

158786- Central Trains, South West Trains, Scotrail, Northern.

 

[43096]

I’ll throw an HST power car in. 43067/467 has worked for Cross-Country, GNER, Network Rail, Grand Central and EMT.

Likewise, 43196 has worked for Cross-Country, MML, GNER, Network Rail and GWR.

For a unit that was withdrawn in BR days 201001 has managed a few - Connex South Eastern, Anglia and Great Western (on Glastonbury services). Any others?

150245 - Scotrail, Northern Spirit, Anglia Railways, Central Trains, Arriva trains Wales.

 

[61653 HTAFC]

successor TOCs don't count, so for example Anglia, One, NXEA and Greater Anglia wouldn't apply.

Just to clarify on this point, if a unit was with Anglia and then transferred to Wales & Borders, stayed for a few years and then moved to Greater Anglia would you count that as two TOCs or three?

If renumberings count the original 170399 scores highly. I believe it worked for Scotrail, Anglia, Midland Mainline, Central Trains, South West Trains, then became 170309 at Transpennine and is now 168329 at Chiltern.

That'd be two.
