Look like they did one hell of a job putting 3252 back together.
From NTSB Shady Grove Wreck Report:
Pages 7 and 10
"Car 3252, the lead car of train T-111, sustained the most extensive damage. The shell of the car became partially disengaged from the frame and came to rest partially on top of the lead car of the gap train. (See figure 5.) The fiberglass end cowl of the car was pushed inside the carbody, and the end underframe assembly moved rearward
10 as a unit, collapsing several of the transverse beams aft of the unit, buckling the floor, and upsetting passenger seats. The operator’s compartment was completely crushed. (See figure 6.)"

Strictly speaking, the impact caused the front end underframe assembly to remain stationary, or nearly so, while inertia drove the rear of the car forward.

"The impact sustained by the lead car (3252) of Train T-111 sheared the huck bolt fasteners attaching the bolster to the side sills, broke the welds attaching the transverse members of the draft sill to the side sill, and sheared off the ends of the side sill. The ends of the side sills remained attached to the front end sill. The side sills, once free of the end underframe assembly, moved outward and allowed the end underframe assembly to move rearward as a unit relative to the body shell. The lead car of the gap train telescoped approximately 21 feet into car 3252."
