It Is Always Great To Draw A Caboose

Cabooses make great practice drawings.  They take about half the time of a locomotive and are a great way to work on logos, lettering and keeping your lines straight.
Cabooses and freight cars are often very colorful.  This gives you a chance to work on trimming around color breaks, such as on yellow hand rails and around windows.
Cabooses are rich in history as well.  They are also just as recognizable as engines.  Often at shows, I have had people specifically ask for my drawings of cabooses.
So get yourself a red pen, and draw yourself a caboose or two.  They are truly a great piece of railroad equipment to get in hours of practice.  I find myself drawing many cabooses both for practice and for fun.  Enjoy drawing trains.
