Fireman’s Courage Saves Lives After Fatal Locomotive Explosion in Norwood-This Day In Norwood History-April 23, 1910

The quiet evening of April 23, 1914, was shattered by a violent explosion along the New York, New Haven & Hartford Railroad’s Midland Division as a freight train passed through Norwood near Warren Street. The blast came from the locomotive’s injector—a critical valve that regulates water flow into the boiler—sending a torrent of scalding steam through the cab. Within seconds, engineer Laurence Koldenborg, 34, was thrown from his post, and his fireman, Joseph J. Kellett, 40, was left to face the inferno alone.

Kellett had just finished shoveling coal when the injector burst. The cab filled instantly with 200 pounds of pressure worth of steam, blinding him and burning his face and arms. Unable to see or breathe, he realized that his engineer might already be dead—and that the train, still moving at nearly twenty miles per hour, could become a runaway. “It was up to me,” he later told a reporter, his voice raw with grief and exhaustion.

Clinging to the outside of the locomotive, Kellett crawled along the gangway, feeling his way toward the engineer’s window. Half inside and half out, he reached blindly for the throttle, closed it, and applied the brake. The train slowed and came to a stop after traveling roughly six hundred yards. His quick thinking prevented what could have been a catastrophic derailment or collision on the busy Midland line.

When the steam finally cleared, Kellett and the crew searched desperately for Koldenborg. They found him unconscious on the tracks, his skull fractured and limbs broken. He was rushed aboard the 7:40 train bound for Boston, but he succumbed to his injuries before reaching Dorchester.

Koldenborg’s death struck deeply across the railroad community. A native of Denmark, he had immigrated to the United States sixteen years earlier and built a respected career as an engineer. He lived in Needham Heights with his wife, Emma Clews Koldenborg, and their three young children. Known for his steady hand and professionalism, he was a member of Norfolk Lodge of Masons and the Brotherhood of Locomotive Engineers, organizations that embodied the pride and solidarity of early‑20th‑century rail workers.

Kellett, meanwhile, returned to his modest home at 144 Whitfield Street, Dorchester, his burns still fresh. His wife ran a small bakeshop and notions store in the front of their house to help support the family. When interviewed later that night, Kellett refused to call himself a hero. “I don’t want anything said about the way I stopped the train,” he said quietly. “I feel awfully about the engineer, who was one of the best fellows on the road.”

The tragedy underscored both the peril and the professionalism of railroad life in the early 1900s. Locomotive crews worked amid constant danger—steam pressure, fire, and mechanical failure—but their courage kept the nation’s freight moving. In Norwood, the story of Kellett’s bravery and Koldenborg’s sacrifice became part of the town’s industrial memory, a reminder of the human cost behind progress and the quiet heroism found in everyday duty.
