An exhaust pipe fire would not cause an explosion. It would not reach far enough back in the train, and would not last long enough to cause damage to
a car. Fires at derailments are caused either by sparks from derailing equipment, over-heated rail equipment (wheel bearing, etc), or electrical
sparks from something hit by the derailing cars ( light posts, power poles etc).
There will be some other reason for the derailment an fire. Most likely it will be a combination of several failures that worked together. Excessive
speed would be one possible issue, but the only "autopilot" currently in widespread use in North America will maintain an extremely slow speed for
loading purposes. It can't even be activated at road speeds. If the news network is reporting this, then more than likely they are mis-interpreting
something else that was said by the railroad.
There are many many things on and near a railroad that can break and cause a derailment. One of those things is the crew. No mention of them in the
