These 40'-6" single sheathed wood box cars were built as above and featured 3138 ft3 capacity. For a more detailed explanation of which groups were built with which appliances, see Tony Thompson's review of the Challenger HO brass import in the SPH&TS magazine Trainline #70 (winter 2002) or his book Southern Pacific Freight Cars Volume 4: Box Cars.
These cars represent a very common prototype which ran into the 1960's. Many of these cars were rebuilt with steel sides and some were placed into Overnight service and received the black Overnight paint scheme. There are many variations of original equipment, rebuilding and renumberings.
