Here’s the second gondola car in progress. This one will end up becoming AC 10588, which is one of several cars modified as a boom car for one of the ACR light diesel cranes.
Rebuilt from one of the cars in the AC 4804-4850 series, the additional unique features of this car include the angled cut offs at each end which allow the crane’s boom to clear and swing over the car. Also, slightly hidden inside the car’s side walls appears to be several equipment lockers as well as a support frame for the crane boom to rest on in transit.
This evening I managed to assemble the sides of this car with low ends, and also applied the basic end bracing to both cars. Major parts still to be done on both cars is the entire underframe and floor (obviously) and the finer details like grab irons. Then of course the additional equipment storage lockers for both cars.
