There were 11 locomotives of this class, built during 1853-1856. Some authorities give the wheel diameter of the "Pluto" and three other engines as 42", and the total weight as 69,600 lb. All the "Camels" were subsequently rebuilt as Moguls. |

| latter carried
as much as 18,000 or 19,000 pounds on the leading wheels, which was regarded
as excessive. Hence these engines were subsequently rebuilt by the Railroad
Company and four-wheeled trucks were substituted for the single pair of
leading wheels originally applied.
In addition to the Baldwin locomotives of the 2-6-0 type, the reports of the Pennsylvania Railroad Company indicate that during the years 1852-1854, twelve locomotives with the same wheel arrangement were built |
"Camel" locomotives, built by Ross Winans, of Baltimore, were placed on the Pennsylvania. These locomotives all had 19 x 22inch cylinders and driving wheels 42 or 44 inches in diameter, and averaged 59,000 pounds weight each, in working order. The peculiarities of the Winans "Camels," with their long over-hanging fireboxes, firing chutes, cam-operated valve gear and other exceptional features, are well known and will not here be described in detail. The earlier of these locomotives underwent consider |

In all these loco motives the leading wheels were held in rigid | able modification shortly after they were placed on the Pennsylvania, and the last five were built without the firing chutes and with the fireboxes closed at the rear. These Camel locomotives were all subsequently rebuilt as Moguls (2-6-0 type) at Altoona, | |
There were nine locomotives of this class, and three of similar design but with 72-inch drivers. |

placed immediately back of the cylinders, as shown in the illustration
of the "Latrobe" on page 13. This arrangement was undoubtedly originated
by James Millholland, Master of Machinery-of the Philadelphia and Reading
Railroad, and was first used in the "Pawnee" class, built by that road
early in 1852. It was a distinctly new design at the time, and was the
forerunner of the true "Mogul" type, introduced about ten years later,
and which subsequently became very popular.

of them remained in service as late as 1880-1882. The majority of the Norris
locomotives placed in service on the Pennsylvania during this period were
of the American (4-4-0) type. In 1853, 12 such locomotives were built for
passenger service, three of them having 72-inch drivers and the remaining
nine, 60inch drivers. In 1853 and 1854, eight of similar type, with 54-inch
drivers, were built for freight service.
The Norris locomotives had quite a reputation for speed, but their details-especially |
