How a Jackson 6700 Tamper Lines and Surfaces Track
Today I'm gonna show you what happens outside my Jackson 6700 tamper as
I am lining and surfacing track. Will give you a very good explanation of
how the Jackson 3 point light system works on the outside in the video
and also a bit more of what happens with the voltages in the description
below and how the machine knows how to lift and line track.
The lights on the light carriage shine through the small slit in the masks back
to the sensors. When the light shines on the center of the receivers this
is called a balanced condition in the track surface or alignment. If the light beam is
above or below the center receiver photocells this is called an out of balance condition.
In an out of balance condition the electrical signal that is created indicates
in which direction and the magnitude of how far away from a straight line
the mask is. A positive voltage will be created when the light band is below
center of the sensor in proportion to the amount the track is low and
produce a negative voltage when the light is found above center of the sensor.
This signal either positive or negative is shown on my jacking and alignment
meters in the cab so I know where the track surface is before jacking or
lining the track occurs. Then when the jackbeam moves the track to where
the signal becomes zero voltage, that shows on my meters as being in
the center of each meter or as we call it, "in the green".
Hope you watched the first video in this 2 part mini series on the hopper cars rocking really
bad thru a section of track, if not the link is here:

There are several videos where you can be in the cab of my tamper as I am
operating it on a playlist on my channel here:
