Hello, what means "railroad and railroad class 1A and 1B? Where I can find the meaning of the infrastructure lines (line types) how them appear in Configuration, for ex. roads and railroad classification are for US or for another country?
Thanks and regards.

Those are classifications used in the US by the USGS in their DLG products. Class 1A would be more major rail routes and 1B more minor ones.
Let me know if I can be of further assistance.
Thanks,
Mike
