I just ordered a K2 Turnout Track Set and a Kato HO/N Scale Premium Pack. My question is that do I need to buy a DC Converter for Turnout Control? The other Unitrack I ordered is the K-1 Standard Track Set. I am just a beginner and just wondering what else do I need to get my Kato train going. P.S. This question was also asked in the N/Z gauge section but I stumbled on to this Technical Q & A. Sorry for double posting.
