where on the internet do i obtain detail parts, re-gearing kits, repowering kits. i would like to add many details to this locomotive. i would like to add MU hoses, realistic looking grab irons and ladders. i would also like to re-gear the loco to run slower. i runs much to fast to be proto-typical; i feel. low speed operation could be improved. i feel that it is a quality product (i could make it prototypical, its a base for something better than out of box) and that i could improve on it and make it more that my atlass loco. i was wondering where i could find aftermarket parts for this peice. also where do i find information on the prototype. it is a chessie #4131. any help would be a appricated.
