George H. Drury’s table of Missouri Pacific steam locomotives built since 1900 is the list on this page. Two Sedalia rebuilds are written down in both forms, so the frames, counted once, are 1,407. The company story is the Missouri Pacific page. Texas & Pacific steam is a separate chapter and a separate roster.

In 1905 the railroad sorted the numbers by the work. Freight power took everything below 5000. Passenger power took 5000 through 8999. Switchers took 9000 through 9999. The class mark put letters on the wheel arrangement and a figure on the driver diameter. P was a Pacific, MK a Mikado, MT a Mountain. A locomotive whose drivers measured 63 inches over the tire carried 63 in the class. One Ten-Wheeler class is TN-56½.
The table below follows Drury row for row, including locomotives that came with the International-Great Northern, the New Orleans, Texas & Mexico, the St. Louis, Brownsville & Mexico, and the smaller Texas roads named in the notes. Where a number was used twice because the shops rebuilt the engine, both lines stay in the quantity column and the frame is counted once in the 1,407.
The 0-6-0s in the table come to 149. No. 9301, class SW-51, was the last steam locomotive on the railroad, still at work in November 1955. It had 51-inch drivers, 21-by-28-inch cylinders, piston valves, Walschaerts gear, and a weight of 160,500 pounds, with a tractive effort of 39,100 pounds. The five rows of 0-8-0s come to 85, the figure Drury gives for the eight-wheel switchers. They followed the United States Railroad Administration design as the Missouri Pacific modified it, heavier by 12,000 to 18,000 pounds and with 7,750 pounds more tractive effort. Later engines had cast frames and a front-end throttle ahead of the stack.
Consolidations 1–172, class C-63, were the first locomotives after the 1905 renumbering. They had 22-by-30-inch cylinders, 63-inch drivers, and slide valves. The first 76 used Stephenson gear. The rest used Walschaerts. Many were later rebuilt with piston valves, Baker gear, stokers or oil, and new cast frames. In 1942 the North Little Rock shops assembled No. 173 from remnants of that class, spare parts, and a new tender. It is in the quantity column. The C-55s numbered 401–487 are carried as 84 locomotives.
The big Mikado purchases were 1201–1280, then the United States Railroad Administration light 2-8-2s 1301–1325, then 1401–1570. Schenectady built 1201–1250 in 1911, fifty engines, and Baldwin built 1251–1280 in 1913 and 1914. They had 63-inch drivers, 27-by-30-inch cylinders, 170 pounds of boiler pressure, and a tractive effort of 50,160 pounds. The 1401–1570 series followed the Administration heavy Mikado, with a larger boiler, a cast trailing truck, and mechanical stokers. They were the first Missouri Pacific locomotives with a head brakeman’s shelter on the tender deck. Engines 1536–1570 had extra space between the second and third drivers because they were built while the three-cylinder 1699 was on test.
No. 1699, built by Schenectady in 1925, was tested at Altoona before delivery. In 1937 the shops converted it to two cylinders and renumbered it 1571. That number sits outside 1401–1570. It is the same frame, listed once. The smokebox door, set a little above center, was the visible difference from the 170 copies of the Administration engine.
Berkshires 1121–1125 were the International-Great Northern’s first 2-8-4s, close in design to the Chicago & North Western J-4. Lima’s 1901–1925 of 1930 used the same cylinder and driver dimensions and weighed 412,200 pounds. They worked St. Louis–Kansas City. In 1940 and 1942 Sedalia lengthened the boilers, rolled new cast underframes with 75-inch drivers, and turned the same 25 frames into 4-8-4s 2101–2125. The cylinders stayed 28 by 30. Boiler pressure went to 250 pounds. Both numbers are in the table. The frames are in the 1,407 once.
The only articulated locomotive was 2-8-8-2 No. 4000, Baldwin, 1912, class ML-55, assigned to the hump at Dupo, Illinois. In the 1920s the 0-8-0s took the hump and the Mallet was stored. It came back in 1927 with a 12-wheel tender and Bethlehem auxiliary engines on both trucks, worked the Dupo hump until 1947, and then, with the boosters removed, handled transfer trains across the Mississippi River bridge and an occasional helper turn on Kirkwood Hill.
Eight Russian Decapods, 941–948, were the secondhand 2-10-0s, bought from the Southern Railway, the St. Louis & Hannibal, and the Marion & Eastern, converted to oil, and sent to the New Orleans, Texas & Mexico. The Santa Fe type 2-10-2s were 1701–1729. Numbers 1701–1714 had been Iron Mountain 1501–1514. Numbers 1715–1719 came from the Wabash in 1942 and went to helper service on Kirkwood Hill. Numbers 1720–1729 were rebuilt late in the Second World War with roller bearings, lightweight rods, trailing-truck boosters, and large tenders.
Brooks built the Atlantics 5501–5540 with 79-inch drivers, the highest on the railroad. Fifteen arrived in 1904, two years after the first 4-6-2s, and twenty-five more, through 5540, arrived in 1907. After 1941 many received cast trailing trucks. In 1942, Nos. 5513 and 5538 were given 73-inch drivers and assigned to light, fast freight on level track.
The Missouri Pacific and the Iron Mountain took their last new Ten-Wheelers in 1900–1902, 101 engines, renumbered 2301–2401 in 1905, with 61-inch drivers. Two engines of that weight, 158,500 pounds, were still on the Gurdon–Norman, Arkansas, run in the summer of 1955 because the bridges would not carry a heavier diesel. Diesels took the job by September 1955, after the bridges were replaced or strengthened. The smaller Ten-Wheelers in the table came with the Gulf and Texas roads. Numbers 371–378 were rebuilt in the railroad’s own shops.
Missouri Pacific 4-6-2 1159, class P-73, with train 1, the Sunshine Special, southbound at San Marcos, Texas, in August 1945. No. 1159 is one of 1156–1161, built for the St. Louis, Brownsville & Mexico. Emery Gulash photo.
Drury calls 6501–6521 the first Pacifics built for service in North America. Nine, then numbered 1115–1123, went to the Missouri Pacific, and twelve, 1616–1627, went to the Iron Mountain. In 1905 the class was rebuilt as P-69 with superheaters, outside piston valves, and Baker valve gear, one engine excepted, which received Walschaerts. The class is listed once. Pacific 6000, the three-cylinder experiment of 1925, left that identity in the rebuilding of 1942, when it became the two-cylinder, oil-burning 6001, with roller bearings and an Elesco exhaust-steam injector. The table’s retired cell, “by 1935,” marks the end of the three-cylinder locomotive. No. 6001 is the same frame.
Pacifics 6601–6629 include 6445–6454, renumbered 6601–6610. The class joined the boiler and cylinders of the Administration heavy Pacific to the 73-inch drivers of the light Pacific. Engines 6614–6619 were oil burners with 12-wheel tenders for the Sunshine Special. The St. Louis, Brownsville & Mexico Pacifics 1156–1161, including 1159 at San Marcos, carried Worthington BL heaters, air pumps on the pilot, and extra-large tenders.
The St. Louis, Iron Mountain & Southern was the second railroad to buy 4-8-2s. Schenectady delivered 5201–5207 in 1913, light engines at 296,000 pounds, with the main rods connected to the third pair of 63-inch drivers. The seven United States Railroad Administration light Mountains, 5301–5307, were rebuilt at Sedalia in 1939 as 5321–5327, class MT-75, with 75-inch disk drivers. Both numbers are in the table. The later Mountains 5335–5344, five from Brooks in 1927 and five from Schenectady in 1930, had 73-inch drivers, 27-by-30-inch cylinders, 250 pounds of pressure, and a weight of 386,700 pounds.
Northerns 2101–2125 are the Berkshires described above. No. 2113, in the Kirkwood photograph, is one of them. The retired years in the table run from 1949 through 1953. Baldwin’s 2201–2215 of 1943 were a War Production Board engine. Railroads had to pool orders and use a design already in production, and the Missouri Pacific chose the Denver & Rio Grande Western’s 1800-class Northern of 1938. Baldwin built the Missouri Pacific engines at the same time as a Northern Pacific 4-8-4 order. The Missouri Pacific locomotives had 73-inch drivers, 26-by-30-inch cylinders, 285 pounds of boiler pressure, and about 16,000 pounds more weight than the Rio Grande engines. They lasted until 1956.
The last road trip was on April 7, 1955. Consolidations 40 and 104 pulled a train of nine dead 2-8-0s and a 2-8-2 from Bush to Dupo, Illinois, for scrapping. Switcher 9301 worked on until November.
The quantity column is Drury’s. A leading hyphen in a retired cell, printed here as “by,” means the engines were gone by that year. A trailing hyphen means retirements began in that year and continued. Builder names are spelled out from Drury’s abbreviations. “Schen” in the book is Schenectady. “IGN” in a builder cell is the railroad’s own shops.
