Witnesses at the scene said they saw several people exiting the truck moments before the train hit.
Scott Anderson, who was on the southbound side of the tracks and at the gate at the time, said at least three people rushed out of the vehicle before the train struck and flames erupted.
"It was a fireball for several minutes," he said.
All of those injured were on the train at the time of the crash. A female passenger was killed, officials said.
Just before 9 a.m., Metra reported BNSF train 1242 would "terminate at Clarendon Hills due to striking a vehicle."
Delays were expected, and other inbound trains began accommodate passengers, Metra said in a tweet.
The DuPage County Coroner was called to the scene, according to officials.
Metra said trains on the BNSF line will run with "limited service" both Wednesday and Thursday following the crash.
