New Freight Cars 4-14-17: Round Covered Hoppers

After rebuilding the round covered hopper (as seen in the previous workshop blog) I found out that the rounded 6x8 top & bottom slope pieces came in several other colors, as can be seen here and here. So, through quite a few Bricklink orders (given that many sellers only had one or two of each piece; the gray one took 5 orders by itself just to acquire the round bits!) I acquired several other colors and got building.
