In the SRHA Archives, we have photographs of at least two Ts-class Mountains, 1453 and 1454, in black paint with dog houses on the tender decks. These are the only two 4-8-2s I know of that got the black treatment in the 1940s. In each case, "Southern" was spelled out on the tender sides instead of large numerals typical of freight engines.
* Does anyone know of any other SOU Mountains that were painted black just before dieselization?
* Has anyone seen photos of any black Mountains with large numerals on the tenders?
* Does anyone have a photo to share of black 4-8-2s from the 1940s other than 1453 and 1454?
* What service were the black 4-8-2s used in? We have seen a photo of 1454 (black) on a head-end heavy passenger train but none in freight service.
Of course, I haven't been to the Archives recently. It's possible more photos of black 4-8-2s have been unearthed and I just don't know about them.
