I hypothesized on an earlier thread that the remote sensing device found in the railbed in Philadelphia last night could have been a trigger to throw a switch down the line a short distance.
There have been two head-ons in Texas this month, one at least in New York, and now two in Europe.
Coincidence?
Given the use of trains (albeit with explosives) in Spain? Perhaps not.
Another point...explosives are not easy to carry around in the U.S. Why worry about 50 pounds of TNT when you can use the combined explosive force of 4-8 Diesel Locomotives?
