So This Is Christmas

Merry Christmas is such an infectious feeling I like to feel that way all year around.

So if you are visiting just before Christmas, just after Christmas or even here on Christmas day I am sure you will find something of interest for you and in the spirit of Christmas.

It may be said that Christmas is no longer a celebration but this must be spoken by people that have never had trouble closing their eyes on Christmas Eve in an expectation of what maybe left for them on the carpet under the tree.

I continue to look forward to the surprise on my Grandchild's faces to this day at Christmas events.

Merry Christmas - Merry Christmas - Merry Christmas

The Most Critical Steam Locomotive Components

By Esther Salazar


One of the prime causes for the change in demographic, industrial and physical landscapes in America and other parts of the world is the advent of steam locomotive. These workhorses often traverse continents at speeds previously unheard of. They harness new steam-power possibilities while deliver people and other essential materials. They have also managed to contribute efficiency to modern life. Critical locomotive components include those that produce power, house operators and clear the way.

So that the working locomotive parts will be activated, fuel becomes something essential. Fuel is usually regarded as the tender. Traditionally, steam-operated locomotives made use of coals as catalysts. These shall be burned inside fireboxes, areas square in shape and found underneath boilers. They are considered vital in steam vehicle operation.

The power and the heat that a firebox can produce will usually be relative to its size. This simply means, the bigger the box, the more power it can produce. This is basically why engineers have long been trying to develop larger fireboxes over time. The heat being emanated from a firebox will cause water to boil, further fueling the ride.

The steam that results from the boiling of water will be deposited into vessels or areas referred to as steam chests. These usually rest right below cylinders found in steam engines. After being started, steam will exit steam chests and enter the cylinder. This will force resident pistons down, causing wheels to start moving. Every time the engine strokes, steam will be entering, pushing pistons down. Excess steam will be fed out the exhaust when pistons return to their original position. This powers locomotives.

There are many parts which aid in facilitating the movements and stopping of steam trains. Wheels are comprised of driver assemblies. Functioning cylinders will produce energy that is distributed all throughout the wheels, subsequently causing their movement. Nonetheless, assemblies can become unbalanced because of the weight of the whole apparatus, most especially side rod connections.

Drivers have been made to come with counterweight which were essentials in correcting the weight imbalance. They often appeared like crescents. On the 19th century, bolts were used in affixing the counterweight on to the wheels. The following century, however, counterweights were casted.

The cabin, often referred to as the cab, is the space where locomotive drivers will be accommodated. The design specifications of these areas usually depended on rail lines but also on the time of production. They were often made to be comfortable to stay in for the sake of the train operators.

Pilots, also called cow catchers were what fronted locomotives at their track levels. These have been made looking like wedges and are large in size. Pilots were taken as safety measures. They were made to take out everything that might come in front oncoming trains.

All these locomotive components form part of the vital aspects in running vehicles properly. It is important that train operators and other workers conduct thorough checkups just to ensure that vital parts are without any issue. Operating locomotives with problematic parts bring in big risks because such can lead to insurmountable damages. This must be avoided.
