About this model

This is a tool for cleaning up stray ballast that invariably ends up stuck to the inside of rails or top of sleepers after ballasting track. Before the glue has completely set, carefully run the Ballast Shark along the track and it will scoop up any bits of ballast that would otherwise making running unreliable. Tested on Peco code 55 and 80 N Gauge track. Obviously it doesn't go through points, but they're a whole different nightmare for ballasting anyway ;)
