A closer look at the adding of the ballast, gives a
better idea of what's going on. Here we see the load of steel from
the rail cars being added as counterweight. Note the row of round
holes along the left edge of the picture, these are the fill holes
for the ballast compartments. ( If you look closely, you can see one
just in front of the workers right foot). The scrap steel is dumped (
and shoveled ) into these holes until the compartments below are
full, then a round steel plate is set into the hole and welded in
place to close the hole. |
