I have one of those Hawthorne Village sets that the 2-6-0 loco runs but does not move, i suspect a gear issue. So, i am in the process of taking it apart and I just can't get the body off. I have no literature with an exploded pic and am working in the dark. Can anybody point me to where literature can be had or know the procedure to get the body off? so many detailed pieces to break makes it hard to man handle, lol. any help will be appreciated .
