Steam locomotive part 1

The first locomotive ever made was created by a man named Georgs Stephenson. The locomotive was built in 1803 and this was the first steam locomotive to run on rails. 

1814 is when they finely fired it up. In the 1900s, steam locomotives evolved into more efficient and effective machines. In 1941, the American locomotive company, or LACO, created the "big boy" 4884 class 4000. You're probably wondering, "what does 4884 mean?", well for example:

If you notice this steam engine has two small wheels in the front, 6 big drive wheels, and zero wheels on the back. We do not count the tender. A little sidenote, for some reason steam locomotives are always known as "she's", don't ask me why, I don't know  any reason to it. All I know is that they are "she's". This engine would be known as a 260 with two wheels in the front and 6 big drive wheels. 

This is a "big boy". Their wheels are known as 4884. There are four wheels in the front, there are two sets of Pistons with two sets of driving wheels as well. This means the engine can haul a lot more cars than a normal locomotive which is perfect for the long trains with a lot of production goods and heavy materials. This was built in 1941 and another one came after it in 1943. This one is smaller engine as it is a 4664.
