Modeltech reveals innovative rail aligner

These are a complete waste of time. They are not rail joiners and as far as I can make out you have to solder track to each section making sure its absolutely spot on. There are no instructions and nothing to point out that these are basically templates that do not contain any rail. Looking at the picture I incorrectly assumed that it was showing the underside of the track, you just join your track to these ends and then when the baseboard is matched to its neighbours the line fits neatly and precisely. There is no advantage in using these compared to laying your track across the join and then cutting it. Maybe I'm missing the point here but by needing to solder track directly to these sleepers you are opening the possibility of serious misalignment and cutting the rail too short.
