The Alphabet Route
Maryland is one of these easiest roads to match model paint.
Steam locomotives, diesels in the fireball and speed schemes, early
open hoppers were all painted black. Other freight cars and MOW
equipment in the fireball and speed eras were painted oxide red (called
"box car red" by the WM). Scalecoat or Scalecoat II oxide red is a very good
match. You may need to mix 2 parts caboose red to 5 parts oxide red to
match some manufacturers. You can also mix 1 part Floquil box car red
with 1 part Floquil caboose red to get a similar color. For 70T and
100T hoppers, Floquil zinc chromate primer may be used. Passenger cars were painted Pullman green. Cabooses
were painted "bright red". Caboose red is a good match.
For early Circus era locomotives, MOW equipment, and cabooses, three
colors are needed. The first two are black and white. The
third is a bright red. The best match is a custom mix of
Scalecoat custom made by Mainline Hobby Supply. An
alternative would be "caboose red" which is relatively close, but not
perfect. MODELflex gloss white and signal red match the paint used by
Atlas and Stewart well. Floquil signal red matches the red used by
Life Like and Bachmann well.
