Playing full devils advocate here...
The Class 309 was the first 100mph EMU under BR, are any of them preserved for that reason?
For whatever reason, 309 616 (aka 960101) is on the Tanat Valley and 309 624 (aka 960 102) is on the Lavender Line, 3 cars of each, that is. The Coventry ERM was their first home.
All convenient for Liverpool Street.
WAO
