One of the BRHS meets had invited relatives of both the engineer and the flagman involved in the Naperville Wreck. As I recall things were a little tense between the parties after all these years. I doubt that the shape of the nose (E5 vs. E7) had a lot to do with the extent of the telescoping; perhaps a Shovelnose with its lack of collision posts might have crumpled more into the last car but I imagine the dynamics of the forces in play would have been similar....something about the kinetic engergy in stored in the moving object tends to destroy the stationary object more than the object in motion.... seems I've read something to this effect regarding automobile crashes. It would be interesting to see if the date of the wreck corresponds to the decision to install Red Mars Lights tied into the emergency brake application on the tail cars and shovelnoses of the prewar Zephyr trains....and higher speed steam power.
