It's been a while as I had to gather the minutes to work on the model in the past two weeks. Corona confinement means working from home and it seems like the working days have only gotten much longer ever since. People are longing for relaxation of the lockdown, that's for sure, and I'm looking forward to the day when I can go back to the office.
Anyway, the first truck is finished, with the exception of the wheels, they haven't been glued yet to the axles. I wait with that until there's rails.
No big issues but I had to alter the brake hydraulic parts here and there for proper alignment of the transmission rods. Also, I included a reinforcement with 1mm thick cardboard on the inside of the truck to support the swivel on which eventually the sleeper will rest. Although it looks differently, I did the same for the F7A trucks.
Compared to the F7A/B trucks, it seems that the braking shoes are missing. According to the designer most of the sleepers were equipped with braking discs, which will not be visible in the model as they're hidden behind the wheels.
Braking shoes will be visible and let's see if these could be included as an option in the model as I have seen quite a few pictures of trucks which were equipped with braking shoes. Reference is made to attached pictures. Somehow I would prefer to include the brakes, as it looks more complete and also would be uniform with the F7A (and B). To be continued and feel free to comment!

Welcome to the wonderful world of passenger car minutiae!
You're both right, and both incorrect.
If you look at the photos I linked to in the F7 thread (
here), all of them have disc brakes. No brake shoes.
However, the Model Railroader drawings that you are working from, as well as the pictures you show, most definitely show trucks with brake shoes.
The trucks you are building appear to be closer to the earlier design, so I would recommend adding the brake shoes.
GSC 41-CS-11 Lightweight Passenger Trucks
and
41-CDO Passenger Trucks
Apparentlt this series of sleepers was delivered with the earlier style of trucks (with brake shoes) and at some point had them changed out to the later style (disc brakes).
