Also, the P2s weren't actually as good in practice as they were on paper, the A2/2s actually saw more use than when they were P2s, but no one realized it as they were focusing on the "Thompson hates Gresley." nonsense, even to the point where they made it seem like Thompson was berating Peppercorn, the A2s were built to be mix traffic pacifics, but I'm guessing a lot of factors made it seem like his pacifics were the worst locos ever to be used on the Eastern & North Eastern regions of BR.
