Marietta man dies after car gets stuck on train tracks causing crash

The Cobb County Police Department’s STEP Unit is investigating.  

 

On Saturday morning at approximately 2:47 a.m., a fatal collision occurred on Brownsville Road west of Powder Springs-Dallas Road in Cobb County, Georgia, when a vehicle became trapped on active railroad tracks and was struck by an oncoming freight train. Diego Lamonthe, 26, was traveling along Brownsville Road when he crossed the lowered railroad crossing arms — a critical safety barrier — at the at-grade crossing. A Norfolk Southern freight train traveling southbound struck the front of Lamonthe's vehicle after it became immobilized on the tracks. The force of the collision caused the train to push the vehicle a significant distance, with both coming to rest near Lewis Road. Emergency responders arrived on scene, where Lamonthe was pronounced deceased. The investigation is being handled by Cobb County authorities. No injuries to train crew members were reported in available coverage.

Location and Infrastructure

The collision occurred at a railroad crossing on Brownsville Road, situated west of the Powder Springs-Dallas Road intersection in Cobb County, Georgia — a suburban corridor in the northwestern portion of the county. This area connects several residential communities and sees both local and commuter traffic at varying hours. At-grade railroad crossings like this one are equipped with standard Federal Railroad Administration (FRA)-mandated safety devices, including crossing arms (gates), flashing lights, and audible warning bells designed to alert drivers to approaching trains. The Norfolk Southern freight rail line running through this section of Cobb County is an active corridor used by both freight and potentially commuter rail operations. The proximity to Lewis Road suggests the crossing sits within a stretch of track that passes through a mixed-use suburban area, where driver awareness of active rail traffic remains critical, particularly during late-night hours when visibility is reduced.

Legal Rights and Considerations

Under Georgia law, crossing a lowered railroad gate is a traffic violation under O.C.G.A. § 40-6-140, which governs vehicle behavior at railroad crossings. Families of individuals killed in fatal accidents may have the right to pursue a wrongful death claim under Georgia's Wrongful Death Act (O.C.G.A. § 51-4-1 et seq.), which allows certain surviving family members to seek the full value of the life of the deceased. Potential defendants in railroad crossing incidents may include vehicle manufacturers, roadway entities, or rail carriers, depending on the specific circumstances and findings of any investigation. Georgia's statute of limitations for wrongful death actions is generally two years from the date of death. Recoverable damages in such cases may include funeral and burial expenses, lost future earnings, and the full value of life. Families are encouraged to consult a licensed Georgia attorney to understand their specific rights and options.
