HiBar:
There are six black pipes. They are 1/2 outside diameter. You can buy from Evergreen or Plastruct and cut to size. There are three brackets between the top and bottom loads there are easy to make from flat stock.
I am not familiar with Evergreen however the Pastruct part number is TB-16. If you want black then the number would be TB-16BK. Other colors are sold. TB-16 comes 15 inches long. You may need to purchase the 30 inch length to get black - TBL-16BK
BobbyD:
The pipe loads are packaged separately from the flat car so you would need to attach after purchase. There are black ties in the box available to do so.
I have three cars NIB - two BN and one Penn Central if you are interested in a quote. All three cars are green.
