| Louis,
Actually, the combined speed of two colliding objects does not make the damage more severe. The article in the following link explains the phenomenon which many people wrongly assume. Since the passenger train, no. 23, was stopped per it’s crew’s report, the damage was marginally less severe. The E5, no 9914B, actually absorbed some of the energy from the freight train impact which moved it backwards, telescoping the Havelock baggage car no. 994.
The article mentioned that the Mythbusters TV program where they wrongly assumed that the force of the collision would be greater when two vehicles collide than if one vehicle hit a wall at the same speed. Some people took exception to their conclusion, so in a later episode, they tested the theory with identical vehicles. The results was that the damage to two vehicles colliding was similar to one vehicle hitting a solid wall at the same speed. They also drove one vehicle into the solid wall at twice the speed which resulted in significantly more damage. If you can find the later episode on TV, the results are very convincing and dramatic.
