I need to link a main line laid with Kato Unitrack to a yard lead laid with Atlas flextrack and Peco turnouts. The track has all been matched in terms of height. What are the possible options for connecting the two mfgrs' track? Kato rail joiners are too small to fit the Atlas track and Atlas rail joiners are too loose for the Kato Unitrack. Thanks in advance for your creative solutions!
