Where my two modules join I want to make up my own 5" track joiners that blend with the main lines. This is only for the joint between my two modules, I know that our club will take care of the two ends with their array of sized sections. I've tried one suggestion where adding tape under the ties and ballasting over it. Seems kind of flimsy and I don't think it will stand up to many setups and tear downs. Any suggestions?
