DS has acquired a Percy engine and bridge Megabloks set. We've concocted some extra bridge out of his Duplo but I wanted to get him some 'proper' track which would actually fit onto the bridge, as he has Xmas/birthday cash. All the Megabloks Thomas stuff seems to be playsets and I can't work out what if anything would actually be able to incorporate the bridge as well. Anyone have one of these engine/bridge sets and been able to work it into another set?
