I have an answer about where the bulkheads are located.

First, it helps to recognize this tank as being a 4 course. The 4 sections are full length, from head to head with no splices. Non of the radial rivets are seams joining adjacent sheets such as would be found on radial circumferentially constructed tanks. Each double row of vertical rivets is retaining a single bulkhead. There are gaps between the bulkheads (No single bulkhead separates any two compartments). This tank car has 6 bulkheads, including the two end caps. Total gallonage will be quite a bit less than the original single compartment capacity because of the air gaps between each adjoining bulkheads.
