The Box-The Most Important Part of the Box Car Drawing

Box car drawings have a surprisingly simple beginning.  With a few basic tools, train drawings are fun and easy to practice.
The more you practice drawings such as box cars, the straighter your lines become.  If your initial rectangle is straight, you will find that it truly shows in the end.  Doors, rivets, even lettering are important details, however, if the outside "box" of the box car is not very straight, immediately your eye will see the slant.
Also, throughout the process, as you draw the braces, the door, and line up the lettering, you will find that each of these details becomes skewed if you are lining them up to a top, bottom or side that is not perfectly straight.  So remember, simple as it may seem, the box truly is the most important part of the box car.  Enjoy drawing trains.
