The P40DC is geared for a maximum speed of 103 miles per hour (166 km/h). The P40DC was succeeded in 1996 by the P42DC. A feature unique to the P40DC and P32AC-DM is a hostler stand at the rear of the locomotive providing increased visibility and reversing capabilities to the engineer while conducting reverse operations.

P40DC采用 16缸 7FDL发动机，额定功率 3000kw（4000hp），最高运营速度为 103mph（166km/h）， 交-直 传动；机车质量约121.6t，启动牵引力280KN，持续牵引力169KN。 该型号的命名方式为 P assenger, 40 00hp, DC Traction，也就是 客运型，4000马力，直流电机。 P40DC的驾驶室前方车灯设计与后期型号略有不同，但在后续维修翻新中均被美铁改成了和P42DC一样的设计。

p40dc和p42dc既有单独的机车供电发电机，也可以切换至通过牵引发电机向机供插座供电。 前者需要将转速维持在900rpm，后者则常在停车或怠速下使用。 当转速为720rpm时，所有的牵引发动机产生的电能全部用于列车供电，在列车停车时使用。

The P40DC, designed in conjunction with GE's German subsidiary, Krupp Verkehrstechnik GmbH, featured a monocoque carbody and bolsterless trucks sporting hydraulic shocks and Flexicoil suspension. The locomotive featured GE's trusted FDL16 prime mover along with an 800 kilowatt, 480VAC three-phase 60-cycle GTA33A1 HEP alternator.

p40dc和p42dc既有單獨的機車供電發電機，也可以切換至通過牽引發電機向機供插座供電。 前者需要將轉速維持在900rpm，後者則常在停車或怠速下使用。 當轉速為720rpm時，所有的牽引發動機產生的電能全部用於列車供電，在列車停車時使用。

GENERAL: Amtrak's first Genesis Series unit built by General Electric Transportation Systems in Erie, Pennsylvania. These units first went into service in early 1993 on Long-Distance trains across Amtrak's System. SPECS: Equipped with a 4000 horsepower prime mover and DC Traction Motors, these were the first locomotives of their kind for Amtrak.

The General Electric P40DC/P42DC, also known as the Genesis, is the current primary passenger locomotive of Amtrak. The original P40DC’s 4250 HP while both having a top speed of 100 mph, these units are seen nationwide on short and long-distance trains. The originally delivered P40DC r window,

While similar looking to the P40DC, this locomotive had AC motors, capability to operate as a diesel or from 3rd rail, and was geared for a maximum speed of 110 MPH. Later that year, the final variant was introduced; Amtrak requested an order for 120 diesel-powered units, but faster and more powerful than the P40DC.

Traction Motors: GE 752AH (Four) Maximum Speed: 103 / 110 mph: Tractive Effort (starting) 63,000 lbs: Tractive Effort (continuous): 38,000 lbs: Multiple Unit Capability: Yes: Dynamic / Regenerative / Electropneumatic Braking: Yes: Quantity Built: P40DC (44) / P42DC (228) Dates: 1993 to 2001--Exterior Dimensions: P40DC / P42DC; Total Length: 69 ...

GE and Krupp continued to press ahead, and early in 1993 they finally unveiled the first 'GENESIS' variant, the 4000HP, 103MPH P40DC - classed the AMD-103 (Amtrak Monocoque Diesel-103MPH) by Amtrak. The work wasn't done yet though - the dual-mode locomotives were still being engineered, and were unveiled in 1995 as the 3200HP, 110MPH P32AC-DM ...
