Diesel Logging RR Info Needed

[extra7000south]

I'm looking for information on Semi-Modern logging operations.
Diesel era, late 1960's to the present day.

I'm wanting to do some modeling in this area and need some information...But mostly in the 1970's time period.

If anyone knows about or has any web sites, photos, book, articles for some ideas, please let me know.
(Motive power, structures, operations, etc...)

;D Thanks to all in advance. ;D
