I'd use a more period appropriate typeface/font. That sans-serif is too modern and clunky for a 1920s Interurban Line. Try using Gil Sans (1926) or Akzidenz-Grotesk (1896) Cheers!
but it seems that the original was like that, as shown in this scan. Regards Volkmar
Look at this link: http://www.r2parks.net/D&W.html The font seems taller and the words are spread apart more. I am not an expert, so I can't say exactly what is off, but your's looks too modern. Otherwise, I love your modelling!
