Two truck drivers have been killed in a fiery head-on collision in Sydney’s west. Both semi-trailers, including one carrying a load of bricks, burst into flames following the crash on Lenore Drive at Erskine Park about 1.30pm on Thursday, with firefighters using foam to contain the blaze, a Fire and Rescue spokesman said.

The drivers had not been formally identified and their ages remained unknown, police said.

Lenore Drive between Erskine Park and Wallgrove Road was expected to remain closed for a number of hours as crash investigators made their way to the scene.
