HO 40' Stock Car, T&P #1 (4) Overview
In railroad terminology, a stock car is a type of rolling stock used for carrying livestock to market. A traditional stock car resembles a boxcar with louvered instead of solid car sides (and sometimes ends) for the purpose of providing ventilation; stock cars can be single-level for large animals such as cattle or horses, or they can have two or three levels for smaller animals such as sheep, pigs, and poultry.
