These are magnificent models. With such a long service life, you’ve got quite a wide range of locos to choose from and still be representative. As with most DRS subjects, you’ve also got a great opportunity to refine your double-heading or top and tailing too. That said, just coupled to a DRS 66 looks spectacular! They are reassuringly heavy, but this only adds to the way that they move; just trundling around seems better than main line speed. The detail as many have observed is outstanding; I could stare at these for hours. I guess lots of us are yearning for a pair of escort coaches now…….
