I just discovered my stash of Lego from when I was a kid and the first rebuild project I'm working on with my 5 year old son is Lego Train 7740 (rebuild in progress) and the Postal Carriage 7819 (100% complete). I'm missing one metal conductive rail and two curved rails and two sleepers from the 7740 set (see image). I do have the original motor but it's missing one wheel and I don't have the transformer so I can't even test out what works.
I am thinking of selling all the track and motor and investing in newer Lego rails, engine, battery, RF system and controller as this old set isn't compatible with the newer battery powered stuff, and it looks like my son is going to be as nuts as me for Lego trains. Are there any issues converting this train to run with the new train system? My son is interested in set 60052 and Christmas is around the corner..
I'm rather out of the loop with the value of these older sets and it's not in A1 condition as I played with it as a kid. I'd say it's it pretty good nick for it's age though and only signs of yellowing are on the locomotive clear windows, and a few tracks rails are slightly damaged, no box or instructions. Is it possible to source the missing track pieces for a reasonable cost (I did manage to find a transformer on ebay that was pretty cheap). Or am I better trying to build as much of the set as I can, then sell it to a collector and invest in a newer train setup?
Any help from those in the know would be most appreciated. Cheers.
