Right up close action as we watch a Harsco 6700 SJ2 tamper
surfacing and lining track. Surfacing means the track is being lifted
and cross leveled and super elevation added in if needed. Lining means
the track is being put into proper alignment, i.e. tangent track is made
straight, while curves are given the proper curvature.
When setting up to tamp a section, first the operator will make a plot
of the section which is recorded on a graph on the tamper's computer.
This plot is shown as a bell graph and it is a recording of where
the track geometry is currently at.
The computer then solves the plot as a "best fit". The operator then can
adjust the plot ordinates to build the curvature or tangent that he
wants the track to end up looking like. After that, the operator enters
the super elevation and saves the plot. When tamping track the tamper's
computer automatically aligns the track and adds the super elevation to
the track according to the directions given in the plot.
To raise the track the operator in the cab manually runs the light up
on the light carriage out front via a push button or toggle switch,
then runs it back down again for a run off. Some computers have it
set up so the operator can have the computer do the light raise.

Here's a playlist where I am tamping and showing you other aspects of
my tamper, including making a plot and going over the computer system:

Amtrac of Maryland was again in here the week of April 11, 2022 and
I will have more videos of them tamping to be shown at a much later date.
Amtrac of Maryland is not associated with Amtrak of the passenger trains.
However, Amtrac of Maryland does on occasion tamp track for Amtrak as
a contractor.
