• Grid, Grid iron: British Rail Class 56 diesel-electric locomotive, from the large grilles.

• Gronk: British Rail Class 08 shunter

• Growler: British Rail Class 37 diesel-electric locomotive – (from the engine sound) or nickname for the 20 Metropolitan-Vickers electric locomotives used on London's Metropolitan underground railway between Liverpool Street and Rickmansworth. The name derived from the noise these locomotives made.
