Hello i am Ryan the son of a veteran model railroader who was born into the hobby. Anyway I thought about the crazy idea of converting my dad's 1st generation Athearn Genesis SD70 into a hybrid of either an Atlas or a Kato by changing the gears and possibly the motor to make the old beauty sound as good as it looks which is arguably in some ways better than some of my dad's Katos and Atlas'. My dad was very dissappointed when he first got the genesis expecting it to sound alot better but instead sounded like the typical Athearn which is said by alot to not run the greatest. My dad thinks this project is too hard and borderline impossible but I am alot more optimistic. My question is to all of you is can this be done before I decide to tear the beauty apart and if this "extreme kitbashing project" (as I like to call it) has ever been done I'd like to see some resources on how to do it.
