Im actually almost done with my build but I will start the builders log a little late. I first took a hlw flatcar I got from wholesale trains for $24 and change http://i49.tinypic.com/65mhw7.jpgThen it was painted ruddy brown and I added some supports on top of the flat. These will support the water tank [IMG]
Then I added vertical post and attached the beams on the side.
Once the sides were built up to the desired height I added some supports to the top. The floor for the top will be layed on top of this. (Look its roosters pink knife LOL)
The boards for the top were added
The final steps will be to put some railing on top, ladders to get to the top. The the pump will be added with the hoses and other details. Once all done it will get weathered so everything blends in nice.
