Don’t pick up the black can of paint just yet!...I remove a lot cab numbers and tender lettering and never harm the underlying black......Lionel used two types of paint for cab numbers etc,...enamel & acrylic. ...these are generally pad printed on. ....try 91% alcohol first, use a small bit and just dampen a rag and see if that wipes away the numbers. If not, do the same process with lacquer thinner, again, just ever so slightly damp. NOW, if the lacquer thinner did the deed, let the underlying black “heel” back up, ....in other words, leave it alone for an hour or so before messing with it. The black will have been slightly softened but will harden back up once the lacquer thinner gases back out,...
