Montreal 3-29-58 Joseph Testagrose collection
Commonly called tank engines, these were actually a Forney design with the front truck equalized with the drivers, built to run as fast in reverse as forward to work in suburban service without the need to turn the engine in the opposite direction. Additionally, the firebox and brick arch were designed for the maximum efficiency to reduce smoke in the urban area. Rapid acceleration was a key feature of these steam locomotives.
