Quite definitely, happens to me all the time, especially when visiting KMRC or eHattons.com
As to your dilemma, I'm sorry Gilbert but there is none, there is only one logical choice here, what else should an express passenger engine be called but Velocity, my favourite BR loco. I succumbed to the addiction last October and got a cheap boxed 60532. The Fox plates and numbers were forthcoming before that, just got to break out the T-cut and give it the treatment.
My dilemma was having two Peppercorn A2s and no A1s, but that one will be easy to solve...
