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.
