How do steam trains work?

Answer 1

Steam trains relay on three major factors: coal( or anything that burns), fire and water.The coal, from the tender, keeps the fire burning or you could use a wood or a gas such as propane. The water gets heated by the fire like a pot of water on the stove. Them, the extra steam gets stored into a dome while the rest rushes down the boiler to the pistons. The pistons are what makes the wheels go round and round. There are two sets of pistons on each side and when the steam goes back and forth, you get a hissing sound. The left over steam is sent up the smoke stack. The throttle applies pressure to the steam which gives you the chuffing sound from the stack. From the stored steam in the dome, its used to make the whistle sound. The whistle is shaped to make a specific sound when applied pressure to, thus, the loud whistle sound. You tell this if you see steam comming out of the whistle. If you have anymore questions, go to my website. kimvrr.webs.com
