Well with the 15 people that show up tell you what is wrong...
I look for that kinda stuff to model.
i.e. the D&RGW listed the 5900 Series stock cars. They listed 5963 as a double deck car ONE year only. There was no other proof what so ever that ANY of the 5900's EVER got a double deck. Well of course I took one of my 5900's and modeled it 5963 with the double deck and carried around a copy of that register just waiting for them.
(Of course is what probably a typo by the D&RGW)
But it was fun none the less
