be well packed to prevent having a hump in the road. Excessive dirt should
be placed to the side of the road and used as fill later on.

Cable buried in a trench to cross a road.
15. Crossing a railroad presents a unique situation.
It is not simply
digging a trench, or even trying to go overhead, but it is one that needs
looking into.
During this situation, you will need the shorter cable CX-
11230( )/G (100 feet). Of course, you could get lucky and be at the end of
a reel of cable and have enough to do the job. It presents even more of a
problem with fiber optic cable.
16. You really should consider going under the rails and between the
wooden ties.
There is a set procedure to follow and it is similar to a
buried road crossing. You need to stake on each side of the track. Place
them 1 to 2 feet beyond the rails, but not so far that you have a lot of
loose cable.
Next, you want to prepare a small trench in the stones to
place the cable.
It should be very close to one of the ties.
Pass the
cable through, place it in the trench, and cover it Secure it to each stake
and be sure there is no slack. A tag is placed on the running and standing
end of the cable as depicted in Figure 2-3.
17. An important item to remember is that the train passing over the rails
creates an updraft that could lift the cable.
It could get caught on
something and get broken. Be sure the cable is buried deep enough and is
tight; that is, there is NO slack at all.
