Great Locomotive Chase on Tallulah Falls RR

Am seeking location identification on the Tallulah Falls RR where the scenes of Disney’s movie The Great Locomotive Chase took place. I learn that Atlanta was depicted in Clayton GA.

- On the Tallulah Falls RR, where was the Marietta and Big Shanty (Lacy Hotel) scenes?
- The scene where Fuller (Jeffrey Hunter) and his men pick up the pushcar and impeding Fuller's train to proceed?
- The rails destroyed derailing the pushcar?
- The Allatoona station scene?
- Etowah where Fuller began using the Yonah?
- The meaning of CIWRR on the Yonah tender?
- Kingston?
- The scenes where the box cars were dropped and pushed back toward Fuller?
- Calhoun station?
- Dalton station?
- The tunnel?
- Box car on fire left locked on bridge?
- Ringgold where the General was left abandoned?
- Chattanooga and the Crutchfield House?
- Any other significant scenes?

Please let me know.

Thanks, and blessings, Denny
