In Aurex 1104.30-DB Zeta (a highly Primax-influenced universe), the Railbots were born from Dr. Brian Jones's attempts at reverse-engineering Maximus combiner technology and applying it to Mini-Con anatomy. The Aerialbots, the Protectobots, and the Railbots fought the Constructicons in the Combiner Wars during the Unicron Singularity crisis. Ask Vector Prime, 2015/07/31
