I have long admired the modular N Scale layouts that have track that runs right up to the modules edge and don't require that a connecting section of track and rail joiners be installed at each module junction.
posted about building this small module I left off just before laying the track. As these to modules would always have to be used together, I thought this would be a good place to try a joiner less track connection.
AsiaNrail uses Peco code 55 track, which has a code 80 sized rail embedded into the plastic molded ties. This provides for a very stable rail. Also, because there is only one track in this case, I am able to adjust the alignment of the modules to line up the rails. I'm not so sure how well this would work on something like a multiple track staging yard.
During the recent 8 day long run many 2 to 3 car trains passed over this joint and no derailments at all were reported.
