Just to take this discussion into the asterisk category on things that affect steam loco speed and efficiency, check out the work of Andre Chapelon and Kyost Kylala, which resulted in the Kylchap locomotive exhaust system. This system made the air draw through the firebed more even and reduced back pressure.

Well if those are anything like the Lempor Exhaust Nozzles, it may be fine those "small" steam locomotives in Europe, but sure didn't work worth a darn on a REAL steam locomotive like UP 3985!
