Each sticker set contains enough stickers for an Amtrak locomotive and an Amtrak passenger car or baggage car.  I designed the stickers for a specific customer and decided to make it available for everyone who designs something similar.  The colored red/white/blue piping is 2 plates thick.  There's a set of stickers that's only for the bottom of the carriage car and therefore only has the blue portion.  The gray is so you can cut into it and it will blend into your train.  The gray is "Light Bluish Gray."  Designed for adult collectors who know where to put things.  One of them is a "cafe" car.  

All the stickers have "510" small numbers because I was lazy.  I also give the true numbers also.
