NEW YORK (CBSNewYork) — No one was hurt when a milk delivery truck caught fire outside Penn Station Wednesday morning.

Flames took over the front of the truck that was parked on 8th Avenue and 34th Street just after 8:30 a.m. The smoke went into the subway on 8th Avenue.

The fire only affected the cab portion so the driver still delivered the milk.

It’s unclear what caused the fire
