Some flatcar loads while relativly small were be so heavy they exceded the axle loading limit for a standard (2 bogie) flatcar.
Several Railroads modified flatcars by replacing the normal 2 bogies with two bolsters with bogies at each end which then attached to the
underside of the car body in the same manner as the original single bogie. This reduces the axle loading by almost half. This is the body section
with two additional attachment points (a.bog4 and a.bog5) halfway between the center and each end of the car at at the surface of the boards.
Down-loaders can make custom loads and attach them to this car (they don't have to be the same), Having several custom loads will allow
changing them by making the appropriate changes in the config file. Assemble this car in Surveyor by placing the body section on the track then
select the bolster (kuid2:210518:6501:1) and place them half way between the center of the body and each end.
To add or change custom load(s):
1. Make one or more custom loads that will fit and export them to Trainz as (kind) bogeys.
2. Change the kuid for bogey-4 and/or bogey-5 to the kuid(s) of the custom load(s) desired.
3. Change the name(s) and kuid(s) of the custom load(s) to the kuid-table.
