Finally, I may not be able to make a font based on your submission, but if I do, I will provide you with a complementary copy. Sometimes I base the lettering fonts on photographs, other times I work from company lettering diagrams or stencils. The artwork fonts are even more varied, sometimes they are done freehand, other times I use several photographs for reference. Even in the days of streamliners, the railroads hand lettered their cars. Of course, for lower priority equipment such as boxcars, they simply used stencils.
Some people prefer one format over the other.
On the other hand, if you are only using a word processor, you can still do a lot by placing spaces between characters. If you want to increase the space, add multiple spaces because going to a larger font size will disrupt your line to line spacing. Below are links to the most common. See the documentation included with the fonts for more details. Chances are nothing is wrong.
