Cincinnati Northern/Toledo, Cincinnati & St Louis 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 8/48 (Locobase 16281)

Data from Southern Iron & Equipment Company Specification for Engine No. 1407 (Tidewater & Western #5 SI&E Spec Sheet supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange collection.

Locobase uses the SI&E spec sheet data for data concering this narrow-gauge Mogul. Data are sparse, but the tube heating surface area of 521 sq ft shows how small this little locomotive was. The deep firebox was 20"(508 mm) wide at the bottom, 43" (1,092 mm) at the top and measured 53" (1,346 mm) wide at the front tubesheet.

But that source's builders ID conflicts with several researchers who report that this was a New York Locomotive Works (Rome, NY) engine, works number 23 from April 1883. That locomotive was delivered to the Avondale branch of the Cincinnati Northern as their #10. Some sources say it was the third of four Rome locomotives (works numbers 21-24) road numbered 8-10. All four were sold in June 1883 to the Toledo, Cincinnati St Louis as 48-50 & 90.

48-49 were sold in 1886 to the Portland & Yamhill as their 2-3 and later served the South Pacific Coast 24-25. 90 was sold to the Monterey & Mexican Gulf in 1889, which became the Central Mexicano as their #57 in 1902.

10/50 was returned to Rome in 1885 and sold to the Marietta & North Georgia as their #1. Then it was sold to Virginia's Farmville & Powhatan as their 5, which reorganized as the Tidewater & Western.

Others claim that this engine later took SI&E ID 1526, but that's a larger locomotive. Others report an SI&E summary that Rogers supplied a new boiler for the 10/50/1/5, which would explain why the SI&E record shows that builder. Its boiler pressure setting of 165 psi in 1918 bears that out.

Most agree that SI&E sold this engine to Palmetto Lumber of Jasper, Texas in 1919.
