Trains at more risk of terror than ET3
Steel wheel trains can be derailed by terrorists without explosives, for instance with a bar of thick steel cut into a wedge shape (placed on a curve), or a portable cutting torch -- no illegal explosives needed. Roads, tunnels, and bridges are all at similar risk to explosives as ET3. Fortunately over 99% of transportation death is NOT due to terror.
