The National Transportation Board (NTSB) said recently that a Mississippi River towing vessel's pilot and its captain pushed its tow up against a riverbank too close to a railroad track, leading to a collision and train derailment near Galland, Iowa, on November 13, 2021.
Marine Investigation Report 22/22 details the NTSB's investigation into the collision between the towing vessel Baxter Southern and a BNSF Railway coal train transiting the track along the shoreline of the Upper Mississippi River.
The train struck a barge that was overhanging the railroad track. Two locomotives and ten hopper cars loaded with coal derailed and six of the derailed hopper cars entered the river.
Two train personnel sustained minor injuries.
The collision resulted in US$1.9 million in damages to the locomotive and freight cars. The barge sustained minor scrapes.
During a transit downriver, strong wind gusts made the situation unsafe for Baxter Southern to continue the voyage as planned.
Using the vessel's electronic chart system (ECS), the captain and pilot identified a location on the riverbank that they believed represented a fleeting area safe to push up against.
Neither the pilot nor the captain clicked an exclamation point symbol on the electric chart, which would have showed that the area presented a "Railroad Collision and Trackbed Erosion Risk."
The pilot pushed the tow onto the riverbank, and three crewmembers headed forward on the tow to verify the forward-most barge was clear of the track. While the barge did not cross over either rail, it extended about a foot over the railroad ties.
When the pilot of Baxter Southern saw the light of the approaching train, he attempted to move the tug and tow away from the riverbank.
The train's engineer activated the train's emergency brake when the train was about 300 feet (91.4 metres) from the barge. With only seconds to respond, the activation of the train's emergency brake and the attempt to move the tow occurred too late to avoid the collision.
The NTSB determined the probable cause of the collision was the tow's pilot and captain not correctly identifying a caution area on the electronic chart before deciding, due to the high wind's effect on the tow's empty barges, to push the tow up against the riverbank alongside a railroad track.
"ECS provide a wealth of navigation information to mariners," the report said. "Electronic charting display and information systems (ECDIS) enable users to obtain more information about a feature by querying through a cursor pick.
"There are many features—including warnings and other navigation information—that can be obtained through a cursor pick that are not specifically noted in the default chart display. Mariners should ensure they understand all symbols and applicable advisories identified in their ECS, and owners and operators should ensure that their crews are proficient in the use of ECS."
