Thanks for the additional information, Jim.  I think we will try your suggestion.  It will certainly be good learning!

Thanks for the reply.  I'm sure they are all pre-2000 vintage.  We'll just invest in a new DCC equipped Diesel loco.  These old ones have been fun for him to practice taking apart and reassembling, so they have been instructional in their own way.

Thanks again.  This is one of the best hobbies for working together with all ages and genders!

My grandson (8 Yr old) and I have switched to DCC and have three steam locos with DCC installed.  We have a number of older DC Diesel Locos which we got with a bunch of HO train stuff from a former HO enthusiast.  My grandson loves the diesel locos and we are wondering if these old locos can take DCC and/or if it's worth installing.

I tried to upload a picture of the loco, but it wouldn't take the post!  It's red and silver number 307.  Hope that helps.

We are switching to DCC and have the Bachmann EZ command system.  Would like to replace turnouts with DCC turnouts.  How easy is it to program them on the Bachmann EZ command system? Would be nice to know how this works before investing the $'s.  Thanks!
