Summary My son complained that there was no railway crossing for the new Lego City Train - only a crossing for the old (incompatible) Lego Tracks exists. This poor child has to play with my old toys ;-) ... and I remember from my childhood, that I hated this clumsy big blue crossing, because it was not possible to cross two close parallel tracks. Luckily times have changed. Here is a Mini-Railway-Crossing for the new Lego City Train. The smaller design allows to cross tons of close parallel tracks. Top and bottom sides interlock with basic Lego bricks.
