Built by Baldwin in 1927 as the prototype locomotive of the famous P-7 class, No. 5300 served the B&O while pulling the Royal Blue train, as well as the Capitol Limited train, until it was removed from the B&O's active list in 1957, one year after being renumbered to 100. The locomotive was put on static display in its original 1927 appearance in 1968 while being put on static display at the B&O Railroad Museum.

Trains in one direction were pulled through the tunnel, by a series of electric locomotives that lasted until the end of steam; in the other direction, the train simply drifted down the slope. Dieselization made the electrification unnecessary and it was discontinued in 1952.

Up until 1884 locomotive numbers were reused when locomotives were retired; numbers were not allocated sequentially (unless lower numbers were used up). In 1884, in order to reduce confusion, all locomotives were renumbered to group like locomotives together, and thereafter numbers were retired along

Finally in 1937 the B&O bought the first multiple unit diesel locomotives to power its passenger trains. And in 1937 they ran the first coast to coast use of diesel electric locomotives. The railroad put an end to the steam locomotive experiments, though wartime pressures would lead to purchase

Lowercase letter suffixes were used to denote successive modifications of a design. The "t" suffix was also used to indicate that the locomotive was assigned an extra large tender. In the 20th century, such modifications were common, and the pattern of suffixes could become confusing. At one point

America.

In 1954 a group of steam switchers was renumbered to free up numbers in the 600s and 700s for diesels. Then in 1956 all locomotives were renumbered again. All steam locomotives were renumbered below 1000, thus freeing all four digit numbers for use by the growing numbers of diesels.

Within each letter class, a number was assigned for each successive design. Usually the first class was numbered "1". Locomotives acquired through mergers were renumbered and reclassified to fit into the sequences of numbers and classes.

The B&O did not emphasize standardization, and when road diesels were bought, they were purchased from nearly every manufacturer. By the time of the railroad's purchase in 1963, though, they were well on their way to becoming the
