My American Flyer Big Boy was having a misfire with the sound system, it missed one chugg per wheel revolution. I contacted Ed Goldin about getting it repaired and he agreed to taking the job. I sent it to him and in very short order it was repaired and returned to me. I am attaching a link to a short video of it running on my layout after the repair. This is still my favorite Legacy locomotive, Thank you Ed!
