The Pioneer Zyphyr had several collisions in fact. On October 2, 1939, she ran through an open switch in Missouri into a steam engine, killing the Zephyr crew and destroying the front of the power unit. But the Burlington's Aroura shops with Budd and EMD assistance had the Pioneer Zephyr rebuilt and in operation two months later. She had a second front end collision in 1949 in Texas and another in 1950 in Colorado. No fatalities that last time, though the fireman was seriously injured. So what we see now at the Museum of Science & Industry has been rebuilt multiple times. I found this all out in an old issue of Burlington's monthly magazine (don't have the issue in front of me) and it's a fascinating read.
