The carrying of freight on rail lines is an everyday essential that allows us the food we eat, the clothes we wear & the other items in our daily life. But the transfer of these daily good to our tables is not just a question of loading a box car, or grain car up and sending it on its way to where ever it needs to be as there is more to it that what meets the eye. Trains travel on rails as we all know and the cars that travel on them need to be weighted so that they may travel with ease to where ever they go. Not all rail is the same as there is different weight codes for rails. The code is stamped on the side of the rail to tell then the poundage of the rail, example 139 LB rail divided by 3 equals in a 12 inch section of about 46 lbs x a 3 ft section of rail = 139 LB rail which is standard for main lines, sidings & spurs can be less, 80, 90 or 100 lb. The weight station here has a different set of rails.In front of the small building you will see the rail is situated differently the ties are short and made of hard heavy rubber. The rails are placed on a metal plate that under it have a set of springs and balances so that when the car is placed directly on the rails the springs and balances under it give an exact weight of the cargo & car that carries it so that that car can be sent to its destination properly & safely and with the correct cargo. It is a science that is exact as it has to be so so that the the transfer of goods can be delivered safely & efficiently as possible from manufacturer to consumer............thanks for the peek.
