氣缸是蒸汽機車上，用於容納推動車輪的活塞。氣缸通常位於車輛前端，左右各一。蒸氣自汽室供應，並以逆轉機調節每個活塞循環注入汽缸的蒸氣量。
汽缸內的蒸氣推動當中透過連桿與車輪相連的活塞，進一步推動車輛。使用過的蒸汽會由「煙箱」內的「廢汽噴口」排出，在當中與來自火箱的煙霧混合，最後透過煙囪排放至大氣中。
因為氣缸與鍋爐和火箱有段距離，當氣缸中不再有蒸汽注入時會迅速冷卻。氣缸中的蒸汽會很快地凝結成水，而由於水不像蒸汽能被壓縮，當足夠的水聚集在氣缸中並被活塞推動時，它會使氣缸受損並導致災難性的動力系統損壞。
To prevent this, steam engines come equipped with cylinder cocks. They are usually operated by a lever from inside the cab, and allow water to be expelled from the cylinders. However, since steam escapes through the cocks too, they should only remain open for a short time, typically just a few seconds, when the vehicle begins moving from a standstill.
Cylinders can also fill with water if the boiler is overfilled, or from running the vehicle with the cutoff set in the opposite direction.
