Just purchased a set of n scale data decals for frieght in gothic black and white. The font size is much smaller than what any of the manufacturers has painted on freight cars. In fact it so small my 10 year old can barely read. Did I get a bad set of decals or the the manufacturers painted data really not to scale?
Without an actual measurement of the letter size it would be hard to say, dimensional data isn’t that big. I have a problem reading the data on HO scale cars, I need my reading glasses, so yours may be right.
