hi,im currently expanding my sons 00 railway.the extension will require at least 2 hinged flaps for door access,etc but im not sure how to join the cut sections of track.obviously fishplates would not work.do people just butt the track ends together?will power still get through?unusually,one flap will have to hinge down,the other up.would soldering a short length of flexible wire to each track over the join work?any comments gratefully received,thanks,stephen thomas
