Formation Builder

Check the product numbers you already have. The builder compares them with the car-by-car set contents in our database and lists the sets that fill the gaps, so you can avoid buying a set twice.

Formation Builder

Tick the product numbers you already own. The builder shows which cars you have and which sets complete the formation. It only uses the set contents listed in our database.

How it works

  • Each formation is one maker's edition of a train (for example KATO's J3-set N700S). Sets from different makers or editions are checked separately.
  • A starter set contains the same cars as the basic set, so it counts as those cars.
  • Car splits marked "not confirmed" are assumptions, not maker data.
  • Your ticks are saved only in this browser (local storage) and are not sent anywhere.

Series covered: N700S Shinkansen, E5 Series Shinkansen "Hayabusa".
