  1. I think comparing firebox design begets comparing the A1 and A2 Pacifics of LNER.  If I remember my uncited reading, as-built the A2s were the better loco, but didn't (or weren't) develop much past what they had.   

     

    Actually, better thought, how might have the LNER Pacific line developed if Raven's design won out?

  2. Also, steam-era policy was generally a loco just right for each job.   One large class of 7MT replacing upteen lesser classes made as much sense as former Midland policy of Class 2 or 3 locos in multiple to match the work.  The 'Universal' Mikados in other countries weren't quite as universal as one might think.   On many American lines, a decently-sized Mikado was the bare minimum to maintain any sort of traffic efficiency on even lesser short lines.   

    Japan was the other country married to the arrangement (and the reason for the name.)  Japan is surprisingly mountainous, so more tread offering power was desirable.

  3. The Temple Meads B-set is how I justify Earl of Dunraven on a minimal T-Trak oval.

     

    Wrong road looking good.   I'd say right road for me, but I've lived on the former CN&W my whole life, so it's still wrong road!
