I own a Bachmann Highballer set that is 30 years old and has only been used once. I'll be retiring soon and want to set it up for my grandchildren but some of the track is missing. The straight sections of track are there but the curve sections are gone and so is the section that the power wires connect to as well. I have searched on the internet but I do not know the correct term when looking for the track to hook up the power to (the one piece of track the wires leading from transformer plugs into) so I could use some help. Also...I have no idea how many curve sections should be there. Any help would be great. Thanks in advance.
