Abstract
Disclosed is a railroad train or tank car for transporting oil and other combustible fluids with an outer fluid-filled shell designed to greatly reduce the potential for an explosion if a train car tank derails. The tank car has an outer shell that is surrounded by a flame-retardant fluid that eliminates sparks resulting from derailment that could cause the oil or other combustible fluid contained by the tank car to combust and burn. An additional feature of the invention is a train car coupler with springs on each side so the coupler can move freely. The movement allowed by the springs would prevent derailment that could occur when a train was going around a curve. This is especially beneficial when train cars are of different weights, such that a heavier car going around a curve that gets derailed could not derail a lighter or empty car that is connected.
