What is the difference between...

What is the differece between a division and a subdivision?

A subdivision further divides a division.

So a division is divided up by subdivisions?

Chad, That’s about the best, most correct answer anyone could have given.

The Division would be an overall operating area on a particular region of a railroad,

a Subdivision is a part of the railroad within a particular Division.

Sorry, the phone rang and I had to give the short answer.

First a railroad would typicaly be divided into two or more divisions. As an example SP called this area the Western division. Then within each division usually each major line would be a subdivision, like the Mojave sub, Valley sub, ect.

Thanks guys.
