[Guilford Guy]

GP40-2L is Canadian, and it is not an SD38.

[westsidelumber12]

Please forgive my ignorance, but how do you guys know all of these? Is there a website or book that shows all engine/locomotive models ever produced? I'd love to learn more about this all.

Also, I'm creating my first layout and would love the engines and rolling stock to be as realistic as possible. How do I know if the engines and rolling stock I use are prototypes of the real thing?
