Fire has destroyed an old coal tower overnight at Casino causing disruptions to the Brisbane-Sydney rail corridor.
At least seven Fire and Rescue NSW (FRNSW) appliances, supported by Rural Fire Service (RFS) units and a bulk water tanker, responded to the blaze at rail yards in Bent Street around 1.30am.
Flames quickly engulfed the heavy timber structure.
Fire crews established an exclusion zone and formed a defensive line of hose as the tower collapsed, leaving only its steel infrastructure intact.
The Brisbane-to-Sydney rail line was closed as a precaution as fire crews mopped up and extinguished spot fires at the scene.
The cause of the fire is under investigation.
