B&O 4-6-0 series that was prototype for the All-Nation O scale model kits from years ago, here at Glenwood, Pennsylvania, 6/2/48:

I've heard these were used on what is now the Wilmington & Western.

The 2061 here at Wilmington, May 1938:

And what was once the biggest locomotive in the US, no location, but I suspect the big B&O Baltimore celebration of 1927, though the back of the card says 1921:

None survived, of course.

I think that All-Nation has the wrong Old Maude,,on the B&O???

Old Maude was not a 4-6-0,,,,she was a 0-6-6-0,,Old Maude was the

very first Mallet,,in the USA...built for the B&O RR ,,in 1904,,by

Schenectady Locomotive,,,those of you that has the book B&O Power

Alvin Staufer & Lawrence Sagle,,look at page 171,,too see the correct

Old Maude,,,,Pat.

Two kinds of locomotives here. The 2003 and 2061 are the 4-6-0- prototypes for the All-Nation models. The 2400 is Old Maude. Two different subjects in the same title to save space.
