This is the body of an interactive depressed center flatcar with six 6-wheel buckeye trucks.
There is an attachment point (a.load0) in the center of the car.
To assemble this car in Surveyor, work from the center outward:
1. Place the body section (this item) on the track.
2. Place an inner bolster (kuid2:210518:6564:1) on the track beyond each end of the car.
3. Place an outer bolster (kuid2:210518:6565:1) on the track beyond the inner bolster at each end of the car.
4. Move the inner bolsters under the car inside of the bogey that is part of the car body.
5. Move the outer bolsters under the car outside of the bogey that is part of the car body.
6. When properly assembled there will only be one red and one green arrow and the car will move as a unit.
