What Era, Railroads, & Locomotives are you set on?

[M Sharp]

I'm modeling an era beginning with 1965 and progressing throough 1974. Every 84 sessions will represent a week in June of said year. Then I'll move to the next year. The reason for doing this is because the motive power of the prototype changed with time and I liked the old and the newer power too much to limit the time to just a few years.

I'm modeling the Erie Lackawanna, Chesapeake and Ohio, Grand Trunk Western, Monon, Norfolk and Western, Indiana Harbor Belt, Elgin Joliet and Eastern and Belt Railway of Chicago in Northwest Indiana and South Chicago.

These are the railroads I most enjoyed during my adolescent years.
