Ralph, the Train Dispatcher; Or, The Mystery of the Pay Car

Great writing! From chapter 1:

Ralph sat with his hand on the throttle waiting for the signal to pull out of Boydsville Tracks. Ahead were clear, as he well knew, and his eyes were fixed on three men who had just passed down the platform with a scrutinizing glance at the locomotive and its crew.

Fogg had watched them for some few minutes with an ominous eye. He had snorted in his characteristic, suspicious way, as the trio lounged around the end of the little depot.

"Good day," he now said with fine sarcasm in his tone, "hope I see you again--know I\'ll see you again. They\'re up to tricks, Fairbanks, and don\'t you forget it."
