One of the differences between an ES44AC and an ES44C4 is the air cylinders and linkages on the truck sideframes of the ES44C4; these are part of the traction control system. Every time a variation in grade, traction, or wheel slip occurs, the computer adjusts the pressure in these cylinders to maintain sufficient adhesion, by varying the ...
The AC4400CW was the first GE locomotive to offer an optional self-steering truck design, intended to increase adhesion and reduce wear on the railhead. [1] This option was specified by Canadian Pacific Railway, Cartier Railway, CSX for their units 201-599, Ferromex, Ferrosur, and Kansas City Southern Railway.
In 2006, IAIS also purchased two ex-China Railways QJ 2-10-2 steam locomotives, numbered 6988 and 7081 for special excursion trains and fundraising events. 6988 has been "Americanized", with a paint scheme inspired by Iowa Interstate's ES44AC locomotives. 7081 retains its original China Railways paint with Iowa Interstate badges.

A track geometry car (also known as a track recording car) is an automated track inspection vehicle on a rail transport system used to test several parameters of the track geometry without obstructing normal railroad operations. Some of the parameters generally measured include position, curvature, alignment of the track, smoothness, and the ...
