Here's a clipping of interest I discovered during the research this morning.
Fatal railroad accident
SPECIAL DISPATCH TO THE GLOBE DEMOCRAT
QUINCY, ILL., AUG. 1, 1875 – The passenger train leaving Hannibal for Palmyra at 10 o’clock last night, a few miles west of Hannibal, went through a bridge which had been undermined by the water, letting down the engine and baggage car on top of it. The engineer, Frank Bradley, one of the oldest and best on the road, was found this morning about a quarter of a mile below the bridge. Whether he was killed, or jumped from the engine and was drowned, is not known. The fireman escaped without injury by climbing out and over the baggage car, which lay on the engine.
