Archbar Trucks, snap-fit; 45mm trains

I modified the original model by adding tabs on the sides of the central piece which allows the parts to slide together, rather than needing to be glued. I also created a version that has a beam for Kadee coupler mounting. 

ASSEMBLY

I suggest sliding one end onto the center beam first. Then, put the wheels into their slots. Slide the other end of the axles into the final piece and attach to the center beam.
