The class 201s and 203s are diesel electric units by the way, not 3rd rail electrics. They sound like a class 37 with a burst silencer (very impressive...)
That's a handy list indeed. Was considering doing third rail on my current route but opted for catenary instead. Now I find there are is distinct shortage of UK EMUs with pantograph. I have the 305/306 with errors and I wouldn't mind something else to compliment it right up to modern era.
