Started looking into the lettering and heralds to see what color, font, etc. were needed.  Couldn't find a font that matched the one needed.  The font that Southern Pacific used was "Railroad Roman" but it didn't match what was in the Daylight books I have.  I decided to make my own font.  The lettering in the books were scanned in my computer.  A font program was used to "clean up" the image and create a True-Type font.  It will be used on both the engine and tender.  The Daylight actually used an outline of the letters/numbers and colored the inside an "aluminum bronze".  Here is the font "outlined" and black "filled".

Information was also gathered to determine where all the lettering and heralds go, the sizes, colors, contents, etc.  Still need to get the decals made.  Most likely I'll farm this out to someone who has the proper decal material.
