Nelson was a lorry who worked at the Quarry on loan by Packard & Sons Co.
Nelson, like the rest of the pack, was owned by Packard and Sons Co. He was one of the few to reside on Sodor and worked in the quarry with Oliver the Excavator. It was on one of these occasions that he witnessed the unfortunate death of Bill when the latter fell into the bay.
Under the reign of Alfred Herman (Adolf Hitler), when the workmen left to join the Blockade Committee, Nelson and Oliver were the only ones left doing the work. Unfortunately, one day while the two were working with Ben and Scruff- who were, coincidentally, discussing about the Blockade Committee at the time-Nelson suddenly began to move forward, much to everyone's surprise. Nelson desperately called for help, but it was too late. He drove off the cliff to his death below, which thus caused a small argument between Ben and Scruff, the latter of Ben calling himself jinxed or cursed whenever he came to the quarry.
It was revealed that this accident was actually caused by Mr. M.
