This caboose started out as NS 2002 and was subsequently numbered NWP 6101 and NWP 5591.

It was restored by the Bethlehem ship-yard in SF in 1969 for display in Samuel Taylor State Park.

The NWP/ICC records say this car was built by North Shore in 1904, but a NS "Requisition for Construction and Repair" show the car as having been repaired and repainted in May 1906 for $115.00. Additionally the ledger for the requisitions show no other work on this caboose, proving the car was on hand when the railroad was formed.
