My son, like many small train enthusiasts, loves building towering train tracks. But there was a recurring frustration: his meticulously constructed bridges and inclines would often wobble and collapse from an excited bump during play. We had the standard pillars from most train sets, but they just weren't cutting it for true stability. He'd come to me, a little engineer with a big problem, and said, "Daddy, my trains fall! Make them strong!". I took the oppertunity and designed some for him.
