There’s a BR52 Kreigslok in the Nene Valley Railway, and another in Bressingham steam museum. These are some of the biggest locomotives I’ve ever seen.
Steam in West Germany lasted a decade after the UK - if you wanted a straight out of service steam loco in the 70's, you bought it from DB. The Nene Valley had a number of continental locos and some stock, and there was IIRC an 01 pacific in the Carnforth collection at one time.
