The Richmond, Fredericksburg & Potomac was a bridge railroad, about 113 miles from Richmond to Washington. Chartered on February 25, 1834, it opened to the South Anna River on February 13, 1836, and it remained a Virginia company until October 10, 1991, when CSX Transportation took it. Reporting mark RFP. The slogan was Linking North and South. Six trunk lines held the stock, the freights ran as extras, and the blue-and-grey 4-8-4s carried the names of Virginia generals, governors, and statesmen. The since-1900 steam list is the steam roster. The diesels, 107 locomotives all-time, are the diesel roster. The August 1952 public timetable is on its own page.

E. L. Thompson, in “Richmond-Washington” (Trains, November 1946), dates the charter to February 25, 1834. The object was a railroad north from the state capital toward the Potomac. Rails reached the South Anna River on February 13, 1836, about 20 miles. Thompson calls it the sixth railroad chartered in Virginia and the third to use a steam locomotive. Fredericksburg opened on January 23, 1837. On November 1, 1842, the line reached Aquia Creek, where a dock could take the Potomac steamboats. Construction then paused for more than twenty years.
Washington was already on a railroad. The Baltimore & Ohio opened its 32-mile Washington Branch from Relay, Maryland, on August 25, 1835. Don Phillips, in “Gateway Between Blue And Gray” (Trains, November 1977), describes the trip that remained: the Baltimore & Ohio into the capital, a steamboat down the Potomac, and a stagecoach from Potomac Creek to the Richmond, Fredericksburg & Potomac’s end of track. Aquia Creek retired the stagecoach. It did not yet make an all-rail route.
The Civil War sat on this railroad. Union troops tore up the line repeatedly. The famous job of rebuilding was Herman Haupt’s trestle over Potomac Creek, stood up in nine days, May 6–15, 1862, about 400 feet long and nearly 80 to 100 feet high, after the 1842 bridge had been dropped. That account is on the Civil War railroads page. The company was moving again in 1870, when about 12 miles were added from Aquia Creek to Quantico. There it met the Alexandria & Washington, a Pennsylvania Railroad subsidiary that reached the capital by way of Newington, Woodbridge, and Alexandria. Quantico later became a large post of the U.S. Marine Corps. The meeting at Quantico was the all-rail link along this part of the coast.
George H. Drury’s chapter splits the finished route in two. The northern portion, Washington to Quantico, was two Pennsylvania subsidiaries, consolidated in 1890 as the Washington Southern. The southern portion was the Richmond, Fredericksburg & Potomac. In 1901 the Richmond-Washington Company was formed to operate the two as one railroad. In 1920 the Richmond, Fredericksburg & Potomac absorbed the Washington Southern.
Phillips describes the 1901 purchase as a consortium of six carriers taking control through the Richmond-Washington Company: the Pennsylvania, the Baltimore & Ohio, the Southern, the Atlantic Coast Line, the Chesapeake & Ohio, and the Seaboard Air Line. He puts their share at 76 percent, with the Commonwealth of Virginia holding the rest and a seat on the board. The Pennsylvania’s Washington & Alexandria was turned over as part of making one Richmond–Washington route. Drury, writing about the steam era, describes Richmond-Washington stock as held in equal parts by those same six railroads. The two descriptions belong to different moments, and both are left as their authors gave them.
From 1903 the Washington Southern and the Richmond, Fredericksburg & Potomac furnished road engines in proportion to mileage. Washington Southern switchers worked Potomac Yard. Richmond, Fredericksburg & Potomac switchers worked Richmond. After 1904 the engines were lettered for the Richmond-Washington Line. In 1926 the Richmond, Fredericksburg & Potomac renumbered the roster and classed it for the first time. There were still no class letters. Wiley Bryan, in “Capital Cities Route” (Trains, November 1941), says the railroad described its engines by numbering series.

Double track was begun in 1903 and was largely finished in 1905, except the bridge over the Rappahannock just north of Fredericksburg. That span was replaced with a double-track bridge in 1927. The finished railroad was a fast piece of double track. Ruling grades were 0.6 percent northbound and 0.8 percent southbound. Curves were held to 2 degrees or less, with superelevation. The rail was 130 pounds to the yard, and the line was under centralized traffic control. It could move more than 100 trains a day.
Drury calls it a 114-mile double-track main line. The operating distances used on the railroad were shorter, and they differed by direction, because every train reached Broad Street Station through a loop and arrived from the south. Northbound runs were 113.5 miles. Southbound runs were 113.1 miles. With trackage rights counted, the 1952 figure is 118 miles.

The Richmond, Fredericksburg & Potomac had no commercial branches. Two government railroads joined it. At Accotink, near Newington, an Army line of about 4.5 miles served Fort Belvoir. At Dahlgren Junction, which the railroad placed at Falmouth just above Fredericksburg, a Navy line of about 24 miles ran to the Dahlgren Naval Proving Ground on the Potomac, later the Naval Surface Warfare Center. That branch was afterward cut back to Sealston. The owning railroads, rather than a network of feeders, kept the bridge line full.
Through the 1940s about 90 percent of the business was bridge traffic, and about 70 percent of that was through traffic: phosphate, aggregates, agriculture, cotton, paper, and the rest of what the northern and southern owners handed over. In the passenger years, Florida seasons could put passengers at as much as 40 percent of annual revenue.
Bryan’s named time freights, which the railroad still ran as extras, were the Richmond Merchandise, the Coast Line Special, the Seaboard Special, the Potomac Merchandise, and the Blue Eagle. The passenger names that used the bridge included the Silver Comet, the Silver Meteor, the Orange Blossom Special, the Champion, the Crescent, the Birmingham Special, the Florida Special, the Miamian, and the Palmland. Amtrak began on May 1, 1971, and took most of what remained. Southern’s Southern Crescent, Washington to New Orleans, kept using the Richmond, Fredericksburg & Potomac until 1979.
The railroad’s own steam, from the 1900 Ten-Wheelers through the last 4-8-4s, is tabulated on the steam roster. The early road engines were 4-6-0s, then 4-6-2s. Drury notes that 69-inch drivers became the freight standard, and that the passenger Pacifics grew larger until four Baldwin engines of 1927, Nos. 325–328, weighed 342,600 pounds. Four Richmond 4-8-2s, Nos. 501–504, came in 1924 and 1925. Six Norfolk & Western class K3 4-8-2s, Nos. 515–520, were bought in 1944, stored through the war, and sold to the Wheeling & Lake Erie in 1948. Ten Lima 2-8-4s, Nos. 571–580, built in 1943, were virtual duplicates of Nickel Plate 730–739. Three simple 2-8-8-2s, Nos. 1–3, former Chesapeake & Ohio engines built at Schenectady in 1925, were bought in 1943 for the Potomac Yard hump.
The 4-8-4s were the only engines the railroad named. Baldwin built the five Generals, 551–555, in 1937: Robert E. Lee, T. J. Jackson, J. E. B. Stuart, A. P. Hill, and J. E. Johnson. They were rated above 66,000 pounds of tractive effort, 3,000 tons northbound and 2,500 tons southbound. They were too wide for the tunnel into Washington Union Station and too heavy for the Long Bridge, so they stayed in freight service south of the Potomac. Emergency passenger work, when it came, stayed on the Virginia side.
The Governors followed. Nos. 601–606 came from Baldwin in 1938, and Nos. 607–612 in 1942. Same cylinders and drivers as the Generals, 27 by 30 inches and 77-inch wheels, and about 60,000 pounds lighter. Bryan rates them at about 63,000 pounds of tractive effort. No. 601, in the photograph above, is taking coal at Ivy City in Washington. The ten Statesmen, 613–622, closed the steam purchases in 1944 and 1945, named for Virginians from John Marshall and George Washington through Carter Braxton. George Wythe is No. 620. James Madison is No. 618, a Statesman. No. 605, a Governor, is James Monroe.
Thompson counted about 115 locomotives in the immediate postwar roster, most of them steam, plus a small group of Alco S2s on the switchers. Freight was dieselized first. Road diesels began in 1949. Most of the steam was gone by 1952. The last 4-8-4 revenue runs were on December 17, 1954. About a year later the ten Statesmen were leased to the Chesapeake & Ohio. They came back and were scrapped in 1959.
A southbound passenger train left Washington Union Station on the Washington Terminal Company, used a short stretch of Pennsylvania trackage rights, and reached Potomac Yard. Richmond, Fredericksburg & Potomac rail began past RO Tower. At the south end the train passed AY Tower and Acca Yard, the Richmond freight terminal, and then entered Broad Street Station. The Chesapeake & Ohio and the Seaboard Air Line used Main Street Station. The Seaboard moved its passenger trains to Broad Street in 1959. The loop is why the northbound and southbound mileages differ.

The Chesapeake & Ohio’s own story begins as a branch off this railroad. Virginia chartered the Louisa Railroad on February 18, 1836, and the first trains, in December 1837, ran from Taylorsville, now Doswell, to Frederick’s Hall. Doswell remained the junction.

Drury’s sentence is the short history. The railroad bought diesel switchers before and during the war, and it bought no road diesels until 1949. The switchers were Alco S2s, 22 of them, numbered 1 and 51–71, built from 1942 through 1948. One Electro-Motive SW1, No. 50, came from the Richmond Terminal. Road power after the S2s was Electro-Motive only. E8s took the passenger trains and F7s the freight, three FP7s arrived in 1950, and four GP7s arrived from 1950 to 1953. Those 22 S2s and 47 new road units, 69 locomotives, were the fleet that replaced steam. The all-time list is larger. It adds the SW1, a secondhand F3A, and the second-generation hoods, and it is on the diesel roster.

Even-numbered diesels led north. Odd-numbered diesels led south. The practice shows in the Doswell photograph below: GP35 No. 131, an odd number, is on the point of a southbound freight.

Eight GP35s, built in August 1965 as 111–118, were renumbered 131–138. Five SW1200s came the same year. Seven GP40s followed in 1966 and 1967, nine SW1500s in 1966 and 1967, and seven GP40-2s in September 1972. That was the last new road power.
The owning circle shrank with the mergers. Seaboard Air Line and Atlantic Coast Line became the Seaboard Coast Line on July 1, 1967. Chesapeake & Ohio and Baltimore & Ohio went under the Chessie System. The Pennsylvania entered Penn Central in 1968, and Penn Central entered Conrail in 1976. The Interstate Commerce Commission approved CSX in 1980. The Southern and the Norfolk & Western answered with the Norfolk Southern combination of 1982. By then the Richmond, Fredericksburg & Potomac’s owners were CSX, Norfolk Southern, and Conrail, and CSX held two-thirds. Norfolk Southern had largely stopped using the line. Norfolk Southern and Conrail sold their shares. The agreement is dated October 10, 1991. Those three dates are different events. The main line is still the busy corridor between Richmond and Washington.
Robert Carper, in “Farewell To Potomac Yard” (Trains, February 1992), treats the yard as the place where freight from the north was made into trains for the run south. It opened on August 1, 1906. As built it covered about 450 acres and 52 miles of track. At its peak it covered 526 acres and 136 miles of track. The Pennsylvania strung catenary into the yard before the Second World War. Icing stations and the old pattern of reclassification lost their purpose as the owners merged and the traffic changed. CSX sold the property in the 1990s, and much of the ground has been rebuilt.
