About the EMD GP-40 Diesel Both under the hood and under the frame, the GP40 exemplified EMD’s product line in transition. Along with its less-powerful sister, the GP38, the Geep 40 was the first EMD locomotive with the model 645 diesel motor. Its predecessor, the 567 diesel that had powered EMD locos since the late 1930s — named for its 567 cubic inch displacement per cylinder — had become inadequate to meet customers’ demands for higher horsepower. Remarkably, the 645 was the same external size and weight as the motor it replaced, with the power increase achieved largely by increasing the cylinder bore. In its normally aspirated form, with a Roots blower pressurizing the incoming air, a 16-cylinder 645 cranked out 2000 horsepower; this was the motor in the GP38. The same engine with a turbocharger, however, put out 3000 hp in the GP40, with lower fuel consumption and emissions and improved high-altitude performance; the tradeoff was higher maintenance costs for turbo-equipped engines. A design problem with turbochargers is "turbo lag": because the turbo’s air compressor is powered by engine exhaust gas, the turbo doesn’t become effective until the engine gets up to speed. In Alco diesels, this issue produced thick black smoke as the motors ramped up, earning them the nickname "honorary steam engines." In the 645 motor, EMD’s engineers solved the problem with a gear train and over-running clutch, which drove the turbo at low engine speeds until the exhaust gas took over. While the GP40 heralded the introduction of a new motor, it also marked the beginning of a long goodbye to the four-axle road diesel. Under the frame, railroads were seeing that six-wheel trucks, once an expedient for spreading out engine weight on lighter-duty track, were more suited to the increasing tonnage and speed of modern freight service. The GP40 and its successor, the GP40-2, were the last high-horsepower, four-axle Geeps to sell in large quantities. During a six-year production run that began in 1965, over 1200 GP40s were sold to U.S., Canadian, and Mexican railroads. Notably absent from the list of original owners, however, were western heavy haulers Santa Fe and Union Pacific; both roads purchased fleets of six-axle EMD SD40s and SD40-2s. Although the lighter-duty, four-axle GP38 series continued to be a strong seller, the transition to the six axle, high-horsepower unit — which would become the standard road diesel of the 21st century — began in the era of the GP40.

June 17, 2020 - The M.T.H. HO Union Pacific GP38-2 diesel has arrived and is now shipping to M.T.H. Authorized Retailers. The locomotives are available in limited quantities at your local M.T.H. Authorized Retailer or directly from the M.T.H. website. About the Union Pacific GP38-2 Diesel Produced from 1972 to 1986, the GP38-2 helped inaugurate Electro-Motive’s "Dash-2" series of locomotives and became one of EMD’s all-time best sellers. With over 2200 engines sold throughout North America, rare was the railroad that did not roster these reliable, second-generation EMD workhorses. Building on the success of the GP38 introduced in 1966, the Dash-2 model looked almost identical on the outside but incorporated a host of internal upgrades that lowered exhaust emissions and improved reliability, ease of maintenance, and tractive effort. Most significant was the replacement of the maze of hard-wired circuits, switches, interlocks, and relays — which had characterized first-generation diesels and had been the source of many of their service issues — with modular, solid-state electronics. Other improvements toughened the pistons, rings, and bearings of the 2000-horsepower, non-turbocharged model 645 prime mover. The result was an engine so hard working and dependable that it became as common on American railroads as the F-unit was in the 1950s and ‘60s. Trains magazine recognized this in 1982 by designating B&O GP38 #3802 (a pre-Dash-2 model) as the All American Diesel; the engine resides today in the Baltimore & Ohio Railroad Museum, repainted in its 1982 Chessie System colors. Many GP38-2s have soldiered on for more than three decades and remain in service today on short lines and regional railroads. You can see the locomotive in action on video by clicking HERE.
