Patches are when a car’s reporting marks and often numbers are changed on a car through the use of blacking out (or patching) the old information and painting over with the new information.
Patches offer modellers a way to individualize their cars and often enhance their realism. At least a few patch jobs are essential for layouts, say about, 1990 forward.
Below are a few examples and then an HO example from B. Smith’s LCN RR.
Recently, PLCX 28138 surfaced on the LCN RR.
For all you modellers of more recent eras, happy patching!
