N gauge train model liner

This is a storage liner for model railway vehicles, primarily designed for 1:150 21-meter-class vehicles from Japan. Based on KATO's storage boxes, it addresses the issue of insufficient capacity in the original foam liner. As of March 2, 2026, ten "Shikishima" models stored in this liner for a few month showed no scratches or damage. This provides a simple test for enthusiasts who might be concerned about potential damage to their models. Thanks to @Doocface , this model now supports X/P series and A1. The maximum capacity is ten 1:150 21-meter-class carriages. The maximum length is 143 mm (excluding the coupling), and the maximum height is 35 mm (including the bogie and pantograph). There might be new version for A1 mini in the future.
