Well, that's not right. I'm right here! Basically, this mod is just the black Warbaby GS-4 with the SP 4449 Daylight textures slapped on and the "4449" numbers painted out. Because of this, it uses the Warbaby GEOPCDX files for the locomotive and the tenders. I released this mod 4 years ago tomorrow, and I didn't realize that I hadn't been specific about which GEOPCDX files to use. That's a mistake on my part. Sorry about that. I hope this helps, and welcome to RWA.

P.S. The flying numberboards are above the smokebox on the 4449 model, and the numberboards are above the center of the boiler on the Warbaby model. From my understanding, the boards were above the smokebox before WWII and were moved to the center of the boiler following the War. The boards were moved back above the smokebox when the 4449 was restored to operation for the American Freedom Train in 1975, and again in 2002. The 4449 carried her post-war Daylight colors during the 80s-90s with the numberboards in the center of the boiler and "Southern Pacific" lettering on the tender. Following 2003, she was painted back into her Daylight colors. This time, the pre-war scheme was chosen with the boards above the smokebox and "Southern Pacific Lines" lettering on the tender. The boards have been above the smokebox ever since.
