Here are some photos of an All Nation (Babbit) Atlantic that has been modified to be a B&O A2. The A2 was a Pennsy design so I had to add the Belpaire fire box. At some point the B&O modified quite a few of these and made them similar to their A3 Atlantic. The B&O replace the original drivers with smaller ones and changed many of the features to B&O standards. The Belpaire and inside bearing trailing truck was retained. This engine will run easily on 072 curves and has TMCC and ERR sound.
The photos were taken by students in a special ed class from the Center For Learning Unlimited when the class visited the Angel's Gate HiRailers model railroad club in San Pedro, CA
