Two die in fiery Brisbane truck crash

Two men have died after their trucks burst into flames during a crash in Brisbane's northeast.

The two trucks collided on Port Drive at Lytton shortly after 8pm (AEST) on Friday and were engulfed in flames immediately, police say.

The two male drivers died at the scene.

One of the trailers from the truck blocked a train track, suspending all rail traffic for several hours.

Police said Port Drive was expected to be closed until at least 6am (AEST) and motorists are advised to avoid the area.
