Pullman's family arranged for his remains to be placed in a lead-lined mahogany coffin which was then sealed inside a block of concrete. A large pit had been dug at the family plot in the cemetary. At its base and walls were 18 inches of reinforced concrete. The coffin was lowered and covered with asphalt and tarpaper. More concrete was poured on top, followed by a layer of steel rails bolted together at right angles and another layer of concrete. The entire burial process took two days.
