I am new to railroad modelling. I received a made in Germany N Scale train set for Christmas, I would like to use the Bachman Power Pack 44211. My instructions in English state to use 12V DC only. How would I be able to convert to 12V to use the 44211. Will I be able also to use Bachman N Scale EZ tracks and terminal rerailer with this foreign made set. From what I've read, Bachman would be easy for me to assemble.
