The Knight Train (a.k.a. The Door Crasher) is a heavy duty Batmobile used when the Dark Knight needs more muscle than his usual rides feature. Ablative armour covers most of the outer shell, virtually freeze-proof and heat resistant to over 4000 degrees. The exposed engine compartment allows venting of the extreme heat created by the power plant within.
Even though the Knight Train was designed to be a blunt instrument, able to flip or smash almost any vehicle out of the way and drive through multiple reinforced walls it was created as a tool not a weapon. Armed with a plethora of non-lethal weaponry including a gattling launcher capable of delivering sting, flash/bang, sonic de-stablizer, gas and other grenades.
Like all of Batman's vehicles, it's lead lined and is meant to serve as a mobile command center in addition to a rolling extension of his utility belt.
I had originally wanted to build a Green Lantern Mobile, but when inspiration hit I started to veer off course and decided on a composite Bat/Lantern Mobile. The more I built, the more it became about the black and wanting to create something different while infusing it with mix of retro roadster, locomotive and a pinch of Mater for attitude. I think I'll finish Knight Train's Cars-ification if I can keep my son from completely destroying it in the next day or so.
