B&O Steam Locomotive Roster (Post 1900)

Published: March 19, 2024

By: Adam Burns

Featured here is the Baltimore & Ohio's complete steam locomotive roster after 1900.  The railroad was conceived in 1827, is known as the first fully-fledged commercial railroad in the United States, establishing a blueprint for American railroad development.

Connecting the port of Baltimore, Maryland to the Ohio River, it served as a primary channel of trade and transport, vital in establishing Baltimore as a force in US commerce.

Chartered to build a line from Baltimore to the Ohio River, the B&O faced numerous challenges including complex engineering issues and competition from the newly opened Erie Canal.

It was a testament to innovation with the first American-built locomotive, "Tom Thumb," which helped the B&O triumph over canal competition. It initiated major telegraph system developments, marking the first American railroad to put the telegraph into commercial use.

Its originally opened in 1830, reaching Wheeling, Virginia (now West Virginia) in 1852. Post-Civil War, B&O expanded across Midwest, reaching Philadelphia, New Jersey, St. Louis, and for awhile even Kansas City.

Though financially turbulent during the 20th century, it ultimately became part of the modern CSX Transportation system in 1987. The B&O is remembered not merely as a transportation entity, but as a significant catalyst in the American industrial revolution.

Types

As the nation's first common-carrier, the B&O operated an array of different wheel arrangements, from the ubqitious 4-4-0 to the monster 2-8-8-4.

During the 19th century the railroad relied on the common types of that era, such as the American, Mogul, and early Consolidations (its first being purchased in 1873).

Into the modern, post-1900 time period the B&O acquired increasingly larger, heavier, and more powerful arrangements to handle freight and heavyweight passenger movements over the stiff grades found on its West End.

General freight movements tended to be operated by 2-8-2s, 4-8-2s, and 2-8-0s while large articulateds like 2-8-8-0s, 2-8-8-2s, and 2-8-8-4s worked heavy drag service.  Passenger assignments were generally carried out by 4-6-2s and, in some cases, 4-8-2s.

The B&O was an early proponent of articulated/Mallet designs and, in fact, operated the first example in the U.S., 0-6-6-0 "Old Maude" completed at Alco's Schenectady Works in 1904.  The locomotive was based from Anatole Mallet's 1885 concept and spearheaded on the B&O by superintendent of motive power, John E. Muhlfeld.

Ironically, however, the railroad was not a big proponent of compound steam.  Its most famous large articulateds were the 2-8-8-4 EM-1s acquired in the mid-1940s from Baldwin.
