The earliest locomotives, such as Stephenson's Rocket, had no cab; the locomotive controls and a footplate for the crew were simply left open to the elements. However, to protect locomotive crews against adverse weather conditions, locomotives gradually came to be equipped with a roof and protective walls, and the expression "cab" refers to the cabin created by such an arrangement.
The LMS twins 10000 and 10001 used the design and later locomotive types such as the British Rail Class 37, and British Rail Class 40 utilised cab units but the term "cab unit" is not used in Britain. The Class 37 and Class 40, like most British diesel and electric locomotives, has a cab at each end.
AAR control stand on an EMD DDA40X; Other EMD models are similar. A control stand is a diesel-electric locomotive subsystem which integrates engine functional controls and brake functional controls, [1] whereby all functional controls are "at hand" (within reach of the locomotive engineer from their customary seating position, facing forward at all times). [2]
The locomotives were GP38-2s, GP40-2s and GP40-2Ls, and SD40-2s. To denote the comfort cab locomotives, a "W" was often applied at the end of the model name (i.e. GP38-2W, GP40-2W, SD40-2W), although this was not an official designation. The Montreal Locomotive Works also offered a competitive cab design on their M-420 and M-630(W) models. EMD ...
In 2017, NCDOT started a Cab Control Unit (CCU) program using ex-GO F59PHs. [9] These are used on the Piedmont. In 2023, Amtrak began testing a former HHP-8 locomotive as a cab car with the aim of supplementing or replacing the existing ex-Metroliner cab cars until the Airo fleet arrives. [10] As of July 2024, eight total conversions are planned.
An EMD SD40 A-unit owned by BNSF Railway. An A-unit, in railroad terminology, is a diesel locomotive (or more rarely an electric locomotive) equipped with a driving cab and a control system to control other locomotives in a multiple unit, and therefore able to be the lead unit in a consist of several locomotives controlled from a single position.

The British Rail Class 73 is a British electro-diesel locomotive.This type is unusual in that it can operate on the Southern Region's 650 / 750 V DC third rail power supply, or an onboard diesel engine to allow it to be used on non-electrified routes.
The GE Dash 8.5-40CW was a 6-axle a 4,000 hp (2,800 kW) diesel-electric locomotive originally built by GE Transportation Systems, rebuilt by Norfolk Southern at its shops in Roanoke, VA. The first locomotive started rebuild 2012, with eleven more being rebuilt until 2016. The locomotive is designed to meet Tier 2 emissions standards.
