The end result, 50 loads weighted and glued. This process has doubled the weight of each individual load.
The end view showing Kadee 5's and AR Kits bogies fitted. These wagons probably never had these bogies but they were spare and better than the originals.
The underside showing the cover strip of styrene on the fish belly hiding the weight underneath. This method didn't give too much extra weight, but everything helps.
The finished product. This wagon negotiated tight curves behind other wagons and performed better than I expected. Tomorrow I get the decals to change the numbers on the other 9.
