Sorry everyone for not being clear enough yesterday. Thanks everyone for the suggestions so far. So after looking through the comments and over some up coming stock and hopefully I'll clear up some more what it is we are looking for. Our son currently has the western messenger set and a diesel type loco with the track expansions up to D, currently we use the supplied mat and build it each time on the floor when he wants to play with it. He is asking Santa for the flying scotsman tts model cause he likes the sounds and whistle etc. We have looked at the differences of DC and DCC and decided that we are going to get him the flying scotsman tts when it comes out, we are also looking at getting the mixed freight DCC when it comes out so we replace his DC locos and have them all DCC. What we were wondering mainly is. What's the best way to make his track semi permanent as space is limited however we were thinking about using a wooden board to put it on that can moved in and out the main room so what's the best material to put it on and how to put it down? Since we'll have 2 sets and some extra track we want to try use 3 different lines for the trains to run on in circles/ovals so what's the best kind of track to use, sections or flexi? Space wise we have measured and are looking at a board roughly 5ft x 7ft to work with and we are hoping we can get a tunnel section and maybe a raised section over the tunnel along with a few small stations and road section in it, although I know it might not possible given space restrictions.
