Been a long time since I was trainspotting (yes, I had the anorak and the Ian Allan book of rego numbers. London had the western region hydromatic diesel warship class locos. amazing) but IIRC the London overground rolling stock has to be quite different as the tunnel sizes even above ground don't meet normal BR rolling stock radius for turns. If Thameslink runs on special sized rolling stock I'd admit it, but if's general size, any train, I think I agree. Its just another national rail line.
