Data from the 1917 Alabama Great Southern locomotive diagram book supplied in March 2004 by Allen Stanley from his extensive Rail Data Exchange. The Pittsburgh works number was 1452 in April 1893.
Delivered to the AGS as a cross-compound locomotive using the Pittsburgh variaton of an intercepting valve. As with most such North American compounds, whatever gains in fuel economy might appeared, they didn't compensate for the additional maintenance required and the shops soon reconfigured the 115 as a simple-expansion locomotive.
The AGS renumbered the 115 as 174, perhaps at the same time they replaced the cross-compound setup.
Sold for scrap in March 1913, hence it never took a Southern Railways System road number.
Data from CNO&TP 1893 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. (Thanks to Samuel Smith for his 23 May 2024 email clearing up Locobase's confusion about which Queen & Crescent railroads later joned which larger system.) Works numbers were 2503 and 2505 in November 1878.
These low-drivered Eight-wheelers were used in mixed passenger-freight operations. They later moved over to the Vicksburg, Shreveport & Pacific as road # 317 and 320. Successive rosters show the 320 was gone by 1904 and the 317 by 1911.
