It has the wooden and electric sets.
The layouts are for the wooden sets, though I had my nephew at the weekend, had printed off a couple, and we built them up the best we could using the blue tomy track. Seemed to work, though we don't have the tiny corner pieces that are available for the wooden track.
At Hamleys they have the tomy set built up as a layout for display only, which he enjoyed looking at. There was also the wooden set built up so the kids could play with it, and both me and my better half were not impressed by the quality in comparison to tomy.
On Monday we collected a huge box of tomy road and rail that I bought on ebay (wasn't delivered on Saturday because it was too heavy), unfortunately my nephew went back up north on the Sunday so he never got the chance to play with it. Now I have most of the pieces that I was wanting the tunnel etc in order to try and build extra stuff from like buildings, tunnels etc to work from, and it's payday tomorrow, I can now start to make a serious start on building a permanent Sodor layout for him and he still has enough track left over to make a good 3 or 4 of his own imagination.
If anyone is able to help re scale, I'd be much appreciated. I have been watching the dvds and trying to get decent screen captures to work out buildings using the counting bricks technique. I had figured on trying to build Knapford station, Tidmouth sheds a couple of signal boxes. A tunnel or two, couple of bridges, have the road for Bertie and instead of having the trains going from one end of the island to the other, having them go round in circles and meeting up at Tidmouth.
