The '''EMD GP40-2''' is a 4-axle diesel [[road switcher]] [[locomotive]] built by [[Electro-Motive Diesel|General Motors Electro-Motive Division]] as part of its [[EMD Dash 2|Dash 2 line]] between April 1972 and December 1986. The locomotive's power is provided by an [[EMD 645E3]] 16-[[cylinder (engine)|cylinder]] engine which generates {{convert|3000|hp|MW|2|lk=in}}.

== Production ==
Standard GP40-2 production totalled 861 units, with 817 built for U.S. railroads, and 44 for Mexican railroads. In addition, three GP40P-2s, passenger versions of the GP40-2, were built for [[Southern Pacific]] in 1974, and 279 GP40-2L(W) and GP40-2(W) units, equipped with wide-nosed cabs, were built by [[General Motors Diesel]] (GMD), for [[Canadian National]] and [[GO Transit]] between 1974 and 1976. Of the CN units, 233 were built with a taller and lighter frame to allow for a larger fuel tank.<!-- "L" is for lighter frame --> These units were officially classified GP40-2L but are commonly referred to as GP40-2L(W). The balance of CN's fleet, 35 units, and the 11 unit GO Transit fleet, used standard frames and smaller fuel tanks; they are often referred to as GP40-2(W) but are classified as GP40-2. Total production of the GP40-2 and its variations totalled 1,143 units.
Standard GP40-2 production totaled 861 units, with 817 built for U.S. railroads, 44 for Mexican railroads. Furthermore, 279 GP40-2s were built by [[General Motors Diesel]] (GMD) between 1974 and 1976. In addition, three [[EMD GP40-based passenger locomotives#GP40P-2|GP40P-2s]], passenger versions of the GP40-2, were built in 1974. Total production of the GP40-2 and its variations totaled 1,143 units.{{Citation needed|date=July 2020}}

Although the GP40-2 was a sales success, it sold fewer units than the earlier [[EMD GP40|GP40]] and the contemporary [[EMD GP38-2|GP38-2]] and [[EMD SD40-2|SD40-2]] models. The popularity of high-horsepower 4-axle diesels began to decline with the GP40-2, with 6-axle models gaining in popularity for their superior low-speed lugging performance.

⚫
With the 62:15 gearing (65-70&nbsp;mph maximum) EMD rated the GP40-2 at 55,400&nbsp;lb continuous tractive effort. Some had PF21 module that reduced the output below 23&nbsp;mph, lowering continuous speed down to 11&nbsp;mph.{{Citation needed|date=July 2020}}
Like the SD40-2 the GP40-2 has a reputation for reliability, and many are still in use. Changes such as the modular electronics system improved reliability over the GP40. Their high power-per-axle rating suited them to high-speed service rather than low-speed drag freights.

⚫
With the usual 62:15 gearing (65-70&nbsp;mph maximum) EMD rated the GP40-2 at 55,400&nbsp;lb continuous tractive effort; for compatibility with other units, most (all?) had the PF21 module that reduced horsepower below 23&nbsp;mph, bringing the minimum continuous speed down to 11&nbsp;mph.

The EMD GP40-2 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division as part of its Dash 2 line between April 1972 and December 1986. The locomotive's power is provided by an EMD 645E3 16-cylinder engine which generates 3,000 horsepower (2.24 MW).

Production

[edit]

Standard GP40-2 production totaled 861 units, with 817 built for U.S. railroads, 44 for Mexican railroads. Furthermore, 279 GP40-2s were built by General Motors Diesel (GMD) between 1974 and 1976. In addition, three GP40P-2s, passenger versions of the GP40-2, were built in 1974. Total production of the GP40-2 and its variations totaled 1,143 units.[citation needed]

Performance

[edit]

With the 62:15 gearing (65-70 mph maximum) EMD rated the GP40-2 at 55,400 lb continuous tractive effort. Some had PF21 module that reduced the output below 23 mph, lowering continuous speed down to 11 mph.[citation needed]

Rebuilds

[edit]

Union Pacific has rebuilt 129 of their GP40's and GP40-2's into GP40N's at their Jenk's shop. These units received a microprocessor control system to increase adhesion, control options, and extend the life of the locomotive.[2][3]

CSX has rebuilt only one GP40-2 locomotive, numbered 6041 (originally BO 4141), into a hydrogen fuel cell locomotive in collaboration with CPKC on April 16, 2024. The unit's road number is 2100, and classified as GP38H2.[4]

Preservation

[edit]

• Sonora Baja California 2107 is now preserved in a Museum in Mexicali, MX [citation needed]
