The wind of their passage at one hundred miles per hour made it impossible to jump the space. Bell put his hands together and extended his arms, narrowing his body as if diving off a high board, and plunged. He cleared the back of the tender, and when his hands hit the steel tank, he tried to curl into a tight ball. He tumbled forward, skidded on the slick surface, and reached frantically for a handhold.

He found one wrapping the edge, dragged himself forward, dropped onto the coal pile, scrambled across it, and found himself peering into an empty locomotive cab lit by the roaring flames of the firebox that gleamed through a crack in the door. He climbed down a ladder on the front of the tender and jumped into the cab, a hot, dark labyrinth of levers, valves, gauges, and piping.

He was generally conversant with locomotives from avid reading as a child, schoolboy engine tours hosted by Kenny’s father, and leading a Yale Glee Club midnight excursion to Miss Porter’s School on an Atlantic 4-4-0 “borrowed” from the New Haven Railroad train yards. He left the Johnson bar reverser in the center notch and searched for the throttle.

The throttle would not budge. He looked closely. The train wreckers had screwed a clamp on to hold it in the wide-open position. He unscrewed the clamp and notched the throttle forward to stop the flow of steam into the cylinders. Tens of thousands of pounds of steel, iron, coal, and water just kept rolling. Gently, he applied the automatic air brakes on the cars behind him, reducing about eight pounds of pressure, which also set the locomotive’s brakes. Screeching steel and a violent bucking told him, Too much. He put on more air pressure, easing the brake shoes on the wheels, and tried a softer touch. At last the train began to slow until there came a point at about fifty miles an hour when Isaac Bell realized to his huge relief that he, more than momentum, was in command.

Just in time. He had reduced the train’s speed to a crawl when he saw a red lantern ahead. A brakeman was standing on the tracks, swinging the Stop signal. A passenger train had stopped for a dispatcher’s signal and was blocking the tracks. “Ran back as fast as I could,” shouted the brakeman. “Good thing you saw me. Bumping into us at ten miles an hour, somebody might get hurt.”

“Wouldn’t dream of it,” said Bell.
