Hello: I'm Steve Christiansen.  I'm new to model railroading.  I have been collecting locos for 25 years and am finally building a layout.  I will be modeling N-scale the 1930's through mid 1950's.  I have several 20 year old bachmann locos that have never been run.  Some do not run and I wish to fix these and install DCC decoders.  I have checked the internet and YouTube to see about removing the bodies to no avail.  The first one is a 4-8-4 loco.  Any help as to how to remove the body without breaking something would be appreciated.  Thanks, Steve
