Chessie System (Railroad): The C&O, B&O, And WM

Last revised: September 17, 2026

Chessie System, Inc. was the Virginia holding company for the Chesapeake & Ohio, the Baltimore & Ohio, and the Western Maryland. The kitten in a C on yellow, vermilion, and blue is what the photographs remember. The corporation was chartered February 26, 1973, became parent of the three roads on June 15, and ended when the C&O dissolved into CSX Transportation on August 31, 1987. Reporting marks stayed CO, BO, and WM. This page details the holding company, the paint, and the public trains.

The combination began as C&O control of the B&O on February 4, 1963, not as a merger of the two names. Hays T. Watkins, Jr., C&O president from 1971, wanted one public name. Franklyn Carr put Chessie the sleeping kitten inside a letter C. The first GP40-2 in that scheme, B&O 1977, came out of La Grange in August 1972. Diesels lettered for the family can be found at the Chessie diesel roster.

C&O takes the B&O, 1963

The B&O in 1961 was losing money. Jervis Langdon Jr. was there to keep it out of court. The Norfolk & Western–Virginian combination of 1959 had already opened the modern merger era. The New York Central wanted the B&O. So did the C&O. Alfred Perlman, the Central’s president, argued for a three-way deal or for NYC control. The B&O board went with Chessie coal money. The ICC approved C&O control on December 31, 1962. Direct control closed February 4, 1963. It was not a merger of the two corporations. The C&O left the B&O standing, in part for a Maryland tax exemption and in part because B&O people would not have taken an erasure quietly. Perlman later joined the Pennsylvania. That combination was Penn Central, 1968. The B&O story is Baltimore & Ohio; the C&O is Chesapeake & Ohio.

Western Maryland, 1967

The B&O already sat on Western Maryland stock. C&O/B&O control of the Wild Mary closed in 1967. The WM ran Baltimore–Cumberland–Connellsville, with Elkins and the West Virginia branches. It paralleled the B&O, hauled the same coal, and kept its own pride of railroad. Chessie later took the Connellsville Extension out of service in 1975 and sold or abandoned most of the rest. Little of that map is CSX today. The company is Western Maryland.

Watkins, one name, June 15, 1973

Hays T. Watkins, Jr., became C&O president in 1971. The three roads already shared shops and some management. He wanted a public name that said so, the way the Family Lines name sat on Seaboard Coast Line, Louisville & Nashville, and Clinchfield equipment—except Family Lines was marketing only. Chessie System, Inc., was a Virginia corporation, filed February 26, 1973, and became the parent of C&O, B&O, and Western Maryland on June 15. Departments consolidated. The three charters remained. Sublettering on locomotives and cabooses kept the owner visible. From about 1976 the family ran more as one railroad.

Sleep like a kitten, then a C

The name was C&O’s. In 1933 Lionel Probert, C&O public relations, bought a sleeping-kitten drawing from Guido Grenewald for $5 and wrote Sleep Like A Kitten And Wake Up Fresh As A Daisy In Air-Conditioned Comfort. The first advertisement ran in the September 1933 Fortune. Thomas Dixon, Jr., in Chesapeake & Ohio Railway: A Concise History And Fact Book, is the citation. That campaign is on the C&O page. By the late 1960s the kitten was mostly calendars.

Watkins gave the new look to Howard Skidmore, C&O public relations, who gave it to Franklyn Carr in the creative department. The brief was bright paint for grade-crossing safety and bold lettering. Carr put the kitten’s silhouette inside a C. The carbody field was C&O Federal Yellow; the roof and skirting Enchantment Blue (near B&O Royal Blue); the bands Vermillion. “Chessie System” sat on the yellow. The board approved it.

The first locomotive painted was B&O GP40-2 1977, outshopped at La Grange in August 1972 and unveiled in Cleveland. The number marked the B&O’s approaching 150th anniversary (charter February 28, 1827). That unit went into service as 4100. For GM’s executive conference at the Greenbrier in November 1972, C&O/B&O renumbered a second new unit, 4163, as 1977. Most photographs of “1977” are the second engine. A third celebrity GP40-2, gold with blue lettering, was GM50, EMD’s fiftieth anniversary as a locomotive builder, September 1972; it later became 4164, then CSX 6063.

System map, 1978

Official 1978 system map of the Chessie System family Chesapeake and Ohio Baltimore and Ohio and Western Maryland

An official 1978 system map of the Chessie System family: Chesapeake & Ohio, Baltimore & Ohio, and Western Maryland.

The map was three railroads. C&O still ran Newport News–Cincinnati, the James River Line, Russell–Toledo, and the Pere Marquette in Michigan and Ontario. B&O still ran Baltimore–Cumberland–Chicago and the St. Louis main. WM still showed Baltimore–Cumberland–Connellsville and Elkins. Philadelphia–Jersey City remained Reading / Jersey Central, later Conrail, rights. Chessie coal and B&O merchandise together earned money in a decade when many Northeastern roads did not.

1977, the gold Geep, and two steam trains

Watkins liked to show the railroad. B&O GP38 3802 received a plaque in 1982 when Trains named it the All American Locomotive; it is at the B&O Railroad Museum. The Chessie Steam Special of 1977–78 used Reading T-1 4-8-4 2101, freshly off the American Freedom Train, in Chessie colors for the B&O’s 150th anniversary. Ten states, 54,900 passengers, 18,641 miles. The Chessie Safety Express, September 13, 1980, to November 1, 1981, was a grade-crossing program behind restored C&O Greenbrier 614. CSX did not keep that kind of steam program.

CSX Corporation, then the names die

Chessie System and Seaboard Coast Line Industries formed CSX Corporation on November 1, 1980. The southern roads became Seaboard System on December 29, 1982. CSX Transportation, to operate the railroad, dated from July 1, 1986. The Chessie charters lasted a while longer. Trains Magazine’s family tree: Western Maryland into the B&O on May 1, 1983; B&O into the C&O on April 30, 1987, a week after the B&O’s 160th birthday; C&O into CSX Transportation on August 31, 1987.

New locomotives in Chessie paint stopped with SD50s Electro-Motive delivered in the summer of 1984. The first CSX scheme was grey and dark blue. B&O’s St. Louis main was cut after 1985. WM’s Connellsville line was already gone.

What remains

CSX still runs the C&O and B&O spines: Newport News–Cincinnati, the James River Line, Baltimore–Cumberland–Chicago, Russell–Toledo. Most of the Western Maryland and much of B&O St. Louis and C&O of Indiana are gone. The kitten-C is on museum locomotives, including GP38 3802 at Baltimore, the Huntington shop switcher, and whatever GP40-2s still wear yellow in preservation. The holding company of February 26, 1973, is not.
