The evolution from regular display toys to intricately detailed little-engines have established model trains and railways into widely held and must-have collectibles. The artistic and scientific qualities that come with them is what let any collector enjoy and work his model trains.
Artistry in model railways involve the crafting of tiny sceneries and buildings that include trees, tunnels, and stations. It also involves the attention to details with the train and locomotive’s interior and exterior to make them appear as elaborate as possible.
For the model train’s technical aspect, the wiring/powering of the model train and railway is what makes each wheeled piece move down the tracks. A satisfying feeling for every model train aficionado is achieved in having to own these not so cheap collectibles.
Every hobbyist has an idea of how they’re steam locomotives sprint down their tracks. Yet there are still a few model train hobbyists that still don’t know how actual steam trains run. Electric current that passes along a model railway track is what makes a model locomotive run just like modern electric trains from monorails and subways, but we all know that steam is the fuel for actual steam locomotives. How do steam locomotives channel power from burning coal?
Back in the 1800s, steam locomotives were primed by first releasing the brakes, followed by steam released slowly. Applying power requires collaboration between the engineer and another man (fireman) or two that will shovel coal from the tender to the boiler. Proper synchronization and coordination between engineer and fireman is extremely valuable in order to make the locomotive run at a correct rate and pace. Approximately 1 ton of coal is burned in an hour.
Fire as hot as 2500 degrees burns the shoveled coal within the boiler. Just outside of the firebox is a container that stores water with a very critical role. It is crucial to surround the firebox with water seeing that this will prevent the firebox from melting and the boiling of the water is what will provide the locomotive’s steam-power.
The steam dome stores the generated steam from the heated water and it’s where the throttle from the engineer’s cabin is linked. Released steam is regulated by the throttle lever that is controlled by the engineer and this is brought down to the cylinder of the locomotive. Pistons within the cylinder link up to the rods that are attached in the wheels. The piston goes rearward and onward as steam is supplied everytime which makes the whole train move.
If a model train collector is using a Digital Command Controller, he he would pretty much feel like a real steam train engineer. When a certain command in the throttle is pressed, it sends out a current to the command station, which is like the steam dome, and it sends out a digital packet to the booster.
Representing that of a steam locomotive’s cylinder, the booster regulates the power being circulated to the model railway that makes the wheel of the model locomotive turn.
Now that you have read this article and learned about how real steam locos work, you can now think of yourself performing the duties of a train crew back in the 19th century.
