I suppose. But it sounds more like a movie script - a domestic terrorist attack on a train transporting hazardous wastes?

Admittedly, I've seen youtube videos of train derailments with disastrous consequences - such as the total loss of a few homes in close proximity to the line. ...and that's the best case outcome for the hypothetical terrorist in this scenario. It just sounds like a very technical plan with a lot of variables and low expected yield. Probably easier to highjack an airplane, or (ironically) target a commuter train.

The public could benefit from knowing industrial train schedules. Suppose a commuter would prefer to take an alternate route to avoid being delayed by the passing of a long train at a RR crossing? Maybe a farmer could move his grazing cattle to another field father away from the tracks. Maybe my dad wouldn't have picked a camp site near lines with trains passing at 2am, blaring their air horns. Hell, I bet the timing of passing trains could significantly influence property values - I would want that info before buying a house. Etc.
