Sunset Constrained
Amtrak/NTSB Investigation

On September 22, 1993, Amtrak’s eastbound Sunset Constrained en route from Los Angeles to Miami, carrying 220 individuals on board, roared throughout the Large Bayou Canot Bridge in the vicinity of Cellular, Alabama and derailed.

Three locomotive units, the baggage and dormitory automobiles, and two of the six passenger automobiles had been catapulted into the water. It was the worst educate catastrophe in U.S. heritage. The Countrywide Transportation Security Board was identified as in to look into and used forensic engineering and metallurgy to discover the trigger of this accident.

TMBA was requested to recreate a number of animations of the accident scene dependent on the findings of the NTSB.


This wreck happened soon after a CSX Transportation swing bridge in excess of the Large Bayou Canot in southwestern Alabama (about 10 miles northeast of Cellular) was struck at roughly 2:forty five AM by a barge staying pushed by the towboat Mauvilla (owned and operated by Warrior and Gulf Navigation of Chickasaw, Alabama), whose pilot experienced come to be disoriented in major fog.

The collision compelled the bridge roughly three toes out of alignment and severely kinked the monitor.

At roughly 2:53 AM,[one] Amtrak’s Sunset Constrained educate, driven by three locomotives (just one GE Genesis P40DC range 819 and two EMD F40PHs, quantities 262 and 312) en route from Los Angeles, California to Orlando, Florida with 220 passengers and crew aboard, crossed the bridge at higher pace and derailed at the kink.

The locomotives slammed into the bridge superstructure, producing its destruction. The lead locomotive embedded itself nose-first into the canal bank and the other locomotives, as effectively as the baggage automobile, dormitory automobile and two of the six passenger automobiles, plunged into the water.

The locomotives’ gasoline tanks, every single of which held a number of thousand gallons of diesel gasoline, ruptured on impression, resulting in a enormous gasoline spill and a hearth. Forty-seven individuals, forty two of whom had been passengers, had been killed, quite a few by drowning, some others by hearth/smoke inhalation. A further 103 had been wounded. The towboat’s 4 crewmembers had been not wounded.

Right away prior to the accident, the Mauvilla experienced produced a mistaken flip and entered an un-navigable channel of water. The towboat’s pilot was not correctly experienced on how to go through his radar and thus, owing to the extremely poor visibility in the fog and his deficiency of practical experience, did not notice that he was off-course.

Though he was aware that he experienced struck a thing when his tow collided with the bridge, his first supposition was that just one of the barges experienced basically operate aground. These types of an assumption would have been unwarranted because of to the comparatively abrupt character of a collision with a stationary item.

The bridge span experienced essentially been made to rotate so it could be transformed to a swing bridge by introducing acceptable devices. No this sort of conversion experienced at any time been carried out, but the span experienced not been sufficiently secured against unintended movement.

Even with the displacement of the bridge, the continuously welded rails did not crack. As a result, the monitor circuit managing the bridge method block signals remained shut (intact) and the closest signal continued to display a crystal clear (green) factor.

Had just one of the rails been severed by the bridge’s displacement, the monitor circuit would have opened, producing the method signal to display a end (crimson) factor and the previous signal an amber method indication.

This could possibly effectively have offered the Amtrak engineer ample time to end his educate or at minimum lessen pace in an energy to lower the severity of the accident.
