>>964414Compare the N&W M2 to the NdeM PR-8. The PR-8 was about 4 tones heavier, making it the largest conventional 4-8-0 (only D&Hs's 500hp triple expansion 4-8-0 was bigger). It has a much more attractive look than the M2.
One unusual feature of the PR-8 though, is that the rear drivers actually projected intot he firebox! Obviously only possible with oil firing.
