Does anyone make 3-rail Scale (or close thereto) models of British prototype trains? For example, I know Lionel made the Hogwarts (and similar) set and MTH made some European stuff. I am not asking about older model trains from the 1940s-1960s like Hornby or Marklin, but current offerings. In essence, do modelers in the UK build three-rail layouts and, if so, who makes their trains?
Specifically, I am interested in GWR tank engines or LMS Royal Scot engines. And they would need tinplate wheels to run on three-rail track.
Thanks.
