"Noticed it may be an opportunity... GN, PRR, and the UP had these locomotives, however if you look closely they are very different..."
A "close" look is not required - the differences are obvious.
The PRR 2-8-8-0 (an HC-1 - the only HC-1, I think) at the top is another one of those big, bizarre Pennsy experimentals - I'd love to have one. That's a hint, Mr Lionel and Mr Wolf.

Yes - the ROW is a well-running scale loco; I have the UP version. Mechanically it is made like the MTH RK/Lionel Lionmaster articulateds - 2 motors, and both engines swivel like trucks. Not "accurate" but these big locos look good on big curves and will take small ones well for a 1:48 loco.
