Steam 2-6-6-6 "Allegheny" Powered -- Chesapeake & Ohio Class H-8 #1633

Product Information

Steep grades and heavy coal trains were the rule on the Chesapeake & Ohio Railway's Allegheny Subdivision. By 1940, the road's aging H-7 2-8-8-2s (built in 1923-24) were getting expensive to maintain. When C&O began looking for a replacement, Lima Locomotive Works proposed an all-new 2-6-6-6 articulated locomotive.
 
Designed for speed and power, the design had 67" (167.5 cm) drivers, a monstrous firebox measuring 9 x 15' (6.9 x 11.5 m) and an overall weight for engine and tender of 1,197,400 pounds (538,830 kg) heavier than Alco's soon-to-be-famous 4-8-8-4 "Big Boy." Behind the loco was an equally huge tender carrying 25,000 gallons (95,000 l) of water and 25 tons (22.5 t) of coal. To fit C&O's 115' (34.47 m) turntables, the rear of the tender was raised, putting more weight on the rear truck and requiring a fourth set of wheels. C&O ordered 10, classified H-8 and named "Allegheny" to honor the mountain range where they would soon be working.
 
Now, on the 60th anniversary of the delivery of the first of these magnificent machines, Rivarossi unveils the first all-plastic HO Scale model worthy of the name "Allegheny" (Imported exclusively for North America by Wm.
