The Inner Workings Of Steam Locomotives

The evolution from regular display toys to intricately thorough little-machines have solidified model trains and railways into popular and must-have collectibles. Making it more interesting is the aspect of its artistic and mechanical applications that let any collector enjoy and work his model trains.

A model train collection’s artistic aspects include the crafting of little sceneries and structures that include foliage, tunnels, and train stations. It also takes in the attention to details with the train and locomotive’s interior and exterior to make them seem as intricate as possible.

For the model train’s technical aspect, the configuration of wiring of the model train and railway is what makes each wheeled piece go down the tracks. It’s the feature that gives a model train hobbyist the feel and pleasure in having to own these not so cheap collectibles.

As you already know, model steam locomotives are powered by electricity. But do you know how actual steam trains operate? Model trains run along tracks powered by low-voltage electric current just like modern electric trains from light rails and subways, but their real counterparts use steam to sashay through the tracks. So how do real steam locos run from steam that comes from burned coal?

In the 19th century, the initial action of an engineer to make a steam loco move is to release the brake, followed by a slow release of steam. The shoveling of coal to the boiler done by the fireman and the engineer’s proper actions are what put in power to the steam locomotive. Proper synchronization and coordination between engineer and fireman is extremely important in order to make the locomotive run at a correct speed and velocity. Approximately 1 ton of coal is burned in an hour.

Fire as intense as 2500 degrees burns the shoveled coal within the boiler. Just outside of the firebox is a container that stores water with a very valuable responsibility. It is important to have water in this section seeing that this not only fuels the locomotive but it also prevent the melting of the firebox.

The steam given off from heated steam goes to the steam dome (acts like a car’s carburetor) where the throttle from the engineer’s cabin is connected. Every time the throttle is pulled, the dome releases a specified quantity of steam that goes to the train’s cylinder. Within the cylinder is the piston where the piston rods are attached and these rods are connected to the locomotive’s wheels. The cylinder’s piston then gets its back and forward movement from the steam generated which makes the locomotive run.

If a model train collector is using a Digital Command Controller, he he would pretty much feel like a real steam train engineer. When the throttle is engaged, 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 adjusts the power being distributed to the model railway that turns the wheels on the model trains.

Now that you have an insight on how a real steam locomotive run, you can now think of yourself carrying out the duties of an engineer back in the 1800s.
