Thanks for that link. I searched for decals and couldn't find any in O scale. Most everything is for HO.
I did notice that the shape of the original is quite different than the model. The front is flat on the model and there is some sort of awning above the drivers window. The windows are different. The space where the letter "F" and the destination is very small as well. I suppose a decal could go at the top of the window as well.
