    aside from the fact that its interesting for somebody whos real into freights, it could be helpfull if youre trying to figure out where the cars in your yard are going or came from.

    for instance, you know that car XXXX has letters in it that designate it a refrigerated car. this means its probably carrying some type of vegetables, fruits, or some cold ass shit. where does produce come from? now you have a vague idea of where this certain car has been or will go. or some shit.
