Thanks for the advice
Luckely i am very familiar with bricklink and i am mostly active in the pirates and history sections of eurobricks.
than the next issue my son is turing 5 years old when he gets the train, and i dont like the idea of him messing around with electrick, he really try's to find out how everyting works. ( if you could see what he does with my powertools)
so i don't have to buy new tracks and the rc tracks will combine with the 9v tracks
thank you
