I wanted to know what train Twain and Cable were riding on, traveling from Springfield to St. Louis. So I thought to find information on the train derailment on the bridge going into St. Louis. Behold, a bit from the St. Louis Post-Dispatch: A SENSATIONAL ACCIDENT. A Faulty Flange Causes a Train to Jump the Bridge Track. ‘The passengers on the in-bound Chicago and Alton train this morning at 10 o’clock were treated to a sensation on the eastern approach of the bridge, which they will remember for many days. The train, consisting of a baggage car, chair car, smoking car and sleeper, was proceeding up the approach at the rate of six miles an hour when the cross-over switch east of the east abutment was run over. The engine, baggage and smoking car crossed the switch in safety, but the chair car struck the frog and jumped the track, lodging at an angle of nearly forty-five degrees across the track and switch. The passengers in the chair car jumped to their feet and were soon crowding each other on to the platform of the car, compelling others to step down to the floor of the approach. The train was brought to such a sudden halt that the passengers in the other cars of the train became almost panic-stricken. As soon as quiet could be restored the entrance to the east abutment tower was opened and the passengers sent up to foot it over the bridge or wait until the chair car was jacked back on the track, which operation consumed over a half hour. On examining the switch it was found that it was securely closed, and the fact that the engine and two cars passed over the switch frog in safety left but one explanation, and that is that a flange on one of the wheels of the chair car must have been broken and caught on the frog. A thorough investigation of the accident is being made.
