He said: "I basically dressed up in the attire appropriate for the Dickens Festival, a Victorian-times style, and was looking forward to taking part"
As he made his way there Joshua had to cross a set of railway tracks. He stood on one set of railroad tracks , while waiting for a southbound train to pass him on the adjoining tracks but failed to hear the northbound train approaching him.
Although the train had slowed to about 20 mph , the conductor could not stop the 93-car train in time to avoid hitting the youngster.
Joshua said he remembers seeing an angel during the accident.
He said: "He (the angel) told me it wasn't my time "And I couldn't get up. And that's because he held me down."
Following the accident he spent several weeks in intensive car, recovering from rib fractures, broken vertebrae, a broken arm and punctured lung. His right leg was amputated above his knee.
His mother, Barbara, said seeing her son survive has been a miracle.
She said: "It makes me stronger in my faith, knowing that God was there, right there, when it happened. He had people by his side after the accident happened to hold his hand."
