@lehighline- Thanks for the easy to understand and clearly visible FA vs PA distinctions. I knew about the length, but almost all PW Lionel locomotives suffer that fate, after all they had to go around 0-31 curves except for a very few that were advertised as 0-72. The 4 wheel vs 6 wheel trucks is a good indication and easy to spot however. In effect, I don't run or collect scale locomotives as they cannot run on my layout - max curve is 0-31- so I have to live with the consequences and lack of scale sizing.
So here are some additional cab units...just for fun!
The Lionel C&O #225 Alco FA from 1960
Just a fun shot of 4 of my favorites in a row...
Talk about NOT scale, the Marx FM series is completely NON scale in nearly every way...but they run great and the lithography is superb...just for fun.
A little closer to scale, has simulated 6 wheel trucks, is the Mark Santa Fe #21 F3 from 1950-1954
Two more "fun" sized FM units by Marx, the KCS and Monon
Finally the Marx #99 Rock Island E7, again simulated 6 wheel trucks (not real - only 4 actual wheels).
Well that's about it for any cab units for me...Best Wishes hope your upcoming week goes well.
