Thank you for your answer. It is very helpful. Based on your answer, I may have made a mistake, as a few days ago I bought the 'HORNBY Mixed Traffic Digital Train Set with Siding R1236'. I haven't received it yet, so I don't know the DCC controler off hand, but I guess it is one of the cheap ones you warned me against. For now, so long as it works the two loco's that come with the set, & my Flying Scotsman it will get me started. I do plan to add around 3 more Loco's & a little more track to the layout. I moved house many years ago & only now do I have a little room, hence my new interest. In the future I will have a lot more space & then I will upgrade to better equipment.
