The bogies consist of 2 etches. These fold up and come together, each with slots for the axleboxes. But the wheels must also be positioned with them, as once assembled the chassis is very stiff, and fitting the wheels afterwards is impossible. seperate DHR axlebox castings, and side springs complete the bogies.
Instructions for the assembly of these bogies are accessible by clicking on this linkÂ Â DHR_Bogies.pdf
