The first cabin (later called the cab) was a wooden shell added in 1831 to the rear of the John Bull by Isaac Dripps, master mechanic of the Camden & Amboy Railroad in New Jersey. The Novelty of the Pennsylvania & Reading was the first locomotive to sport an iron cab, in 1847. The modern steel cab was a product of the 1880s. In Canada, the all-weather safety cab (complete with weather-proof rubberized curtains between locomotive and tender) was developed in the 1920s.
