The 1930s opened with the crash still working through the ledgers and closed with the country on the edge of another war. In between, first-track mileage fell from 249,052 in 1930 to 233,670 in 1940. The industry posted net deficits in 1932, 1933, 1934, and 1938. Average return on investment for the decade ran about 2.25 percent. Missouri Pacific, Rock Island, Milwaukee, North Western, New Haven, Erie, and a long list of smaller roads went into court. Union Pacific and Burlington answered empty coaches with the first internal-combustion streamliners in 1934. Electro-Motive answered freight skepticism with FT demonstrator set 103 in 1939.
The automobile and the shopmen belong to the 1920s. The Transportation Act of February 28, 1920, is the 1910s closer on Railroads In The 1910s. Named-train encyclopedias and the Art Deco passenger story sit on Streamliners. The diesel that finished steam is on diesel locomotives. What follows here is 1930 through 1940: Depression filings, two New Deal railroad statutes, the streamliner as a decade event, steam at its technical peak, and a freight diesel that convinced the Class Is. The second war is Railroads In World War II.

Mileage is the Stover / ICC first-track series. Information compiled September 9, 2026.
The map had already stopped growing. Stover’s 1916 peak of 254,037 miles was fourteen years behind. The 1920s had taken the total down to 249,052. The Depression did the first large cutting. By 1940 the same series stood at 233,670—about 15,400 miles gone in ten years, most of it weak branches the 1920 Transportation Act had made hard to abandon until a showing could be made. Kansas and Iowa still looked dense on a map. Whole subdivisions did not earn their keep. The ICC could now let them go, and in this decade it did.
Freight collapsed with the factories. Passenger counts, already down from a billion in 1916 to about 708 million in 1930, fell another third by 1940. Air travel was still a rounding error: about 2 percent of commercial passengers in 1939. The automobile had already taken the short ride in the 1920s. What the 1930s added was empty freight yards, deferred maintenance, and bond interest that could not be paid.
Equity receivership had been the old railroad bankruptcy. Congress wrote a railroad chapter into the Bankruptcy Act on March 3, 1933—Section 77—so a company that could not meet its debts as they matured could reorganize under a federal court with the ICC in the room. The Reconstruction Finance Corporation, created January 22, 1932, was already lending to railroads with Commission approval. The loans bought time. They did not buy solvency. Of the twenty-one largest RFC railroad borrowers, a majority still ended in court or a judicial debt readjustment.
The big names on this page’s live glance are the ones the public remembered. Missouri Pacific filed in the spring of 1933. Rock Island went in on June 7, 1933, in Chicago, Judge James H. Wilkerson. Milwaukee and Chicago & North Western filed a day apart, June 28 and 29, 1935. New Haven followed on October 23, 1935. Erie, after an RFC loan that Chesapeake & Ohio would not fully back, went in January 1938. Frisco had already been in since 1932. Denver & Rio Grande Western, Western Pacific, Chicago Great Western, and St. Louis Southwestern joined the docket. Company encyclopedias stay on those railroads. The 1930s fact is the scale: not a few weak short lines, but Grangers and Eastern trunks in the same courtroom.
The strongest names—Pennsylvania, New York Central, Santa Fe, Union Pacific, Southern Pacific, Great Northern, Burlington—stayed out. They cut dividends, borrowed, and ran what traffic there was. They did not escape the decade’s 2.25 percent return.
The Emergency Railroad Transportation Act of June 16, 1933, created a Federal Coordinator of Transportation. Joseph B. Eastman, already an ICC commissioner, took the job. The statute did not take title. It told the Coordinator to find waste, promote joint use of terminals and shops, and keep the map from eating itself. The office was temporary. Congress extended it once. It lapsed in 1936. Eastman went back to the Commission. The great consolidation the 1920 act had asked for still did not happen.
Trucks were no longer a local nuisance. The Motor Carrier Act of August 9, 1935, put interstate truck and bus operators under the ICC: certificates, rates, and accounts. Railroads had wanted that regulation. They got it. They did not get the freight back. Short-haul merchandise kept moving to the highway. What the 1935 act did was make the trucker a regulated competitor instead of an unregulated one. The later freight story is the history hub and the 1940s. This decade is when Congress admitted the truck was a common carrier.
The 1920s had already shown that the local mixed train could not beat a $260 automobile. By 1930 railroads recorded 34 billion passenger-miles against 175 billion by car; buses held about 15 percent of the commercial passenger market. The Depression then emptied the remaining coaches. Passengers carried fell from about 708 million in 1930 to about 456 million in 1940. Heavyweight limiteds still ran. They did not look like the future. Union Pacific and Burlington bet that a fast, colored, articulated trainset could make headlines and sell tickets. The encyclopedia of that bet is Streamliners. The dates belong here.
Pullman-Standard delivered Union Pacific’s M-10000 in February 1934, a three-car articulated set with a Winton distillate engine of about 600 horsepower, Canary Yellow and Golden Brown, a 60-seat coach and a buffet-kitchen-observation. The railroad called it The Streamliner. The price commonly cited is about $200,000. It could run 110 mph. It was a sensation on the exhibition circuit before it ever earned a dollar in the Platte Valley.
Burlington had ordered from the Budd Company on June 17, 1933. Zephyr 9900, later the Pioneer Zephyr, was unveiled at Philadelphia’s Broad Street Station on April 18, 1934: stainless steel, a Winton 8-201-A diesel of about 660 horsepower, 197 feet, 72 paying seats. On May 26, 1934, it left Denver at 5:05 a.m. and reached Chicago that evening, about 1,015 miles in roughly 14 hours, an average often put near 78 mph. Arrival was 7:10 p.m. The diesel held together. That was the point as much as the speed.

Articulated sets could not drop a car at the shop without parking the whole train. Conventional lightweight consists followed at once. Milwaukee’s steam Hiawatha began May 29, 1935. Baltimore & Ohio restyled the Royal Blue on June 24. Santa Fe’s extra-fare Super Chief left Chicago on May 12, 1936. Southern Pacific’s streamlined Daylight dated from March 21, 1937. New York Central put Henry Dreyfuss’s shroud on the 20th Century Limited on June 15, 1938. Seaboard’s Silver Meteor, the South’s first, debuted February 2, 1939, behind the same E4s that later headed the Orange Blossom Special. Nearly every major road wanted a flagship before the decade ended. The trains did not reverse the passenger loss. They gave the industry a public face while the freight diesel was still a demonstrator.
Super Power was a 1920s idea: Lima’s A-1 Berkshire in 1925, Northern Pacific’s first 4-8-4s in 1926, New York Central’s Hudson in 1927. Those types are on the 1920s page, the 4-8-4 encyclopedia, and the Hudson class page. The 1930s put the same large firebox on bigger engines and then wrapped some of them. Union Pacific’s 4-6-6-4 Challenger appeared in 1936. Southern Pacific’s GS-class 4-8-4s took the Daylight. Pennsylvania showed the S1 duplex at the 1939 New York World’s Fair. Dreyfuss J-3a Hudsons wore the Century. Steam was not a dying craft in this decade. It was still being designed at full size while Electro-Motive sold a different argument.
Switcher diesels that stayed on the property were a 1925 fact (Alco–GE–Ingersoll-Rand). The 1918 Jay Street Connecting experiment had already been returned. This decade is when Electro-Motive took the main line. In 1935 EMC outshopped 1,800-horsepower passenger boxcabs with two Winton 201-A V-12s: Santa Fe’s pair (shop talk called them Amos and Andy) for the Chief, Baltimore & Ohio No. 50, and demonstrators 511 and 512. Streamlined cousins followed in 1937—B&O’s EA and Santa Fe’s E1. They proved a diesel could handle varnish. They did not yet take the freight that paid the bills.
The freight case was the FT. EMC built demonstrator set 103 as a four-unit A-B-B-A, about 5,400 horsepower, on the new GM 567 engine. The tour began in November 1939. David P. Morgan, in Trains for February 1960, put the run at about 83,764 miles on twenty Class I railroads in thirty-five states over eleven months. Santa Fe ordered. Burlington, Great Northern, Southern, Boston & Maine, North Western, Missouri Pacific, and others tested and bought. The diesel hub owns the Tehachapi story and the model encyclopedia. The 1930s fact is that by the winter of 1939–40 the freight diesel had a mileage record, not a prospectus. War Production Board limits then slowed the conversion. That is the next decade.
Pennsylvania finished New York–Washington electrification in 1935 and put GG1s on the passenger runs. That was reconstruction of an Eastern trunk, not a new transcontinental. Milwaukee’s mountain electrification was already a 1910s and 1920s plant. Great Northern’s new Cascade Tunnel had opened January 12, 1929. The 1930s did not add a new electric map. They finished the one Pennsylvania had been building since Penn Station.
Interurbans, which had peaked at 15,580 miles in 1916 and stood at 10,422 in 1930, kept shrinking. Lines that lasted did so as freight short lines. Hilton and Due remain the account; the overview is Interurbans & Streetcars.
The decade did not know it was a prologue. Streamliners sold magazines. Challengers and GG1s and E-units all ran in the same year. The map was smaller than in 1916 and still the largest industrial plant in the country. Bondholders were in court. Eastman’s coordinator had come and gone. Trucks had a statute. The FT had a tour book.
Japan attacked Pearl Harbor on December 7, 1941. This time the railroads stayed in private hands. Management had spent twenty years determined not to be taken again. Record wartime freight and a passenger renaissance are the 1940s, on Railroads In World War II. The 1930s did not win that war. They left the plant, the diesels, and the memory of federal control.
