Thanks Chuck. I just located pictures of two such duplex locomotives: #s 4537 and 4576. They were both classified as 2-8-2s despite also have the 2-8-0 under the tender. The steam pipe to the rear drivers came directly from the boiler, so they must have had all high-pressure steam boilers. The diameter of the rear drivers was smaller than those under the locomotive. They must have been a wonder to hear with the exhause continually going in and out of sinc.

On ebay the other day there was a model listed as a Southern Railway duplex locomotive sporting a 2-8-2-2-8-0 wheel arrangement. It looked like a standard 2-8-2 locomotive with a 2-8-0 under the tender. I checked a website on Southern's locomotive roster, and it did not list this wheel arrangement. Did the Southern Railway ever have such a locomotive? If so, when and where did it operate? Was the locomotive built this way originally or was it a modified 2-8-2 with a 2-8-0 frame added under the tender? How many of these locomotives did Southern have like this? (If I was to guess, I would say it was a one-of-a-kind. short-term, unsuccessful experiment where an older 2-8-0 frame had been added to an existing 2-8-2.) Thanks for your help.
