On June 15, 2001, work began on bonding of the rails. Because the rails form the
return path for the current to power cars,
each stick of rail must be electrically well-connected
to its neighbors.
||Lying down on the job? Bonding underway on
the new trackage, using a portable electric
welder on a push cart.
Since the rails are used as the return path for
the electric current used to power cars, they
must be connected together with copper bonds,
or short jumper wires.
First the area for the
bond is cleaned with an electric grinder, then
the bond is arc welded to end rail end.
orange water cooler was put to good use, as the
bonding went on in some particularly hot weather.
About 170 rail bonds
had to be installed, as well as 8 cross-bonds,
which connect between the two rails across
the track for a better electrical path. >>
