Nothing is in the car at the tail. We have been working with Spirit to use it for delivering parts kits but that’s been an uphill battle. So for now it just protects the tail and provides a place for taggers to do their work. People in my work group have ridden the train all the way, doing studies of locations where the fuselage gets the most damage from coming in contact with trees, brush, rockfall and such.

Maybe future 737s will need gun ports and ball turrets. For protection from the children. They have some cool automated ones these days. Or you could use remote control.

I figure that they could be used as high speed passenger trains, from Kansas anyway.
