How is lettering removed on a TCA car?

I use alcohol & qtip which I buy at the drug store. As they say, try in an inconspicious spot.

My guess is the ink pattern is applied by a pad transfer process.

Magic Eraser will sometimes work.

If you can't get those markings off, why not just paint over that entire panel with a new coat of white? Mask it and shoot.

Rich and Rattler 21, I'm hoping to find a removal method that would do negligible damage to boxcar's original painted white surface to avoid having to repaint it since I don't have an area inside the house where I can spray paint and spray painting outside this time of year in SE PA is impossible due to our below 50 degree cold temps and on the rare days we are above 50 degrees it's usually due to rain and the humidity coinciding with that rain is also not conducive to good spray painting results.
