Chatham-Kent Fire and Rescue officials are still looking for the cause of a fire in Wallaceburg on Tuesday that sent toxic smoke skyward.
The railroad ties on a bridge over Running Creek, part of a section of abandoned railroad, burned Tuesday afternoon.
When firefighters from Wallaceburg and Chatham arrived, the flames were five feet high, and thick, black smoke poured from the blaze.
Due to the location, fire officials called in a tanker team from Tupperville to help establish a tanker shuttle system to provide sufficient water on site to combat the fire.
Due to the toxins produced from the burning ties, fire officials notified the Ministry of Environment and advised neighbouring residents on the matter.
Firefighters managed to get the blaze doused, and the warning to residents was lifted.
The cause remains undetermined at this time.
