That ATSF Challenger looks awesome! That has to be one of my favorite fictional articulated locomotives other than just the German BR53 (was going to be real).
Miss the Old Boxcars, they were quite unique in the fact they were like Rolling Bill Boards, always something different and cool to read what was stamped on them.......
One of the Fun things as KID,,,,,,,Shssssh don't tell anyone, I used to climb on them whenever they were parked on a siding somewhere, just to see if I could do it and have a great view from 10-12 off the Ground.......:hehe:
