The SD90MAC was designed to utilize the new 16-cylinder H-engine, while the SD80MAC was designed to use the 20 cylinder version of the existing 710G engine.

The same cab was later used on EMD's SD70I, SD75I, SD80MAC and SD90MAC locomotives.

The SD80MAC is a C-C diesel-electric locomotive.

The SD80MAC introduced a wide radiator housing similar to GE locomotives and the placement of dynamic brakes at the rear of the locomotive, which is a quieter location, features that were incorporated into the SD90MAC and SD70ACe models.

The SD80MAC is one of the most popular modern locomotives with railfans, partially due to its rarity.

There are two versions of this cab on SD70Ms: the Phase I cab, which was first introduced on the SD60M, and is standard on the SD80MAC and SD90MACs, and the Phase II cab, which is a boxier design similar to the original three-piece windscreen cab in the SD60Ms.

It is, with the SD80MAC, one of the largest single-engined locomotives produced by that company, surpassed only by the dual-engined DD series.

EMD later produced a 20-cylinder 710 series diesel engine for the EMD SD80MAC locomotive.

The SD90MAC, like the SD80MAC, SD70ACe, and SD70M-2, has a wide radiator section, nearly the entire width of the locomotive, which along with their size makes them easy to spot.

The SD80MAC also has recessed red marker lights in the nose, an identifying feature unique to Conrail locomotives, although NS has removed the lights on most of their former Conrail engines.

In 2009, the final SD80MAC in Conrail blue ; NS 7205 ( former CR 4109 ) was repainted NS black.

Ash is a hardwood and is hard, dense ( within 20 % of 670 kg / m³ for Fraxinus americana, and higher at 710 kg / m³ for Fraxinus excelsior ), tough and very strong but elastic, extensively used for making bows, tool handles, baseball bats, hurleys and other uses demanding high strength and resilience.

An unusual form of four-stroke model engine that uses what is essentially a sleeve-valve format, is the British RCV series of " SP " model engines, which use a rotating cylinder liner driven through a bevel gear at the cylinder liner's " bottom " and, even more unusually, have the propeller shaft — as an integrally machined part of the rotating cylinder liner — emerging from what would normally be the cylinder's " top " at the extreme front of the engine, achieving a 2: 1 gear reduction ratio compared to the vertically oriented crankshaft's rotational speed.
