Who manufactures these in HO ? They’d look amazing with some heavy lload on the layout ! But I never came accross one except 40-foot 4-truck flat car - but is isn’t depressed [:(]

can’t seen to view your pictures.

Fixed it ![:)]

Thanks HF, this is what I was looking for.

Does anyone know how trucks are attached ? By screw or snapped-in ?

here’s another location : discounttrainsonline.com/HO-Scale-Freight-Cars-Bachmann/HO_FRT_160_3.html

They are attached by Phillips head screws. The cars come assembled except for the grab irons.

Walthers also makes flat deck heavy-duty, flat deck flatcars (932-5640 series). Eastern Car Works makes a 90-ton, 2 truck, depressed center flat car (117-4800) that could probably be modified to look like a modern 2 truck, depressed center flatcar. Backmann makes a 2-tuck, DC flatcar that looks toy like.
