Behind him, on its way to New York, he could see a freight train coming along.

He could hear, too, Red Gallagher's roar of anger.

It was less than fifty yards, yet already, as he reached the shelter of the tower, the thunder of the freight sounded in Quest's ears.
He glanced around.

Red Gallagher and his mate were racing almost beside it towards him.

He rushed up the narrow stairs into the signal room, tearing open his coat to show his official badge.
"Stop the freight," he shouted to the operator.
