I believe that is a mobile gps mapping system used for many things like creating new track charts etc reflecting what is actually found in the field and exactly where each item, xovers etc, is located.
in the old days, teams of surveyors used to do all the field work used to make these charts. the field data was then relayed to the office engineers who used to direct the drawing of the charts. on a good day single tangent track i'll bet they could almost do a thousand feet a day of field measurements.
these hyrail gps rigs can probably do 30 miles a day producing printer ready material that can be downloaded on any number of computers for any number of applications including track charts.
from a purchasing railroad point of view, this on the money field info well ahead of the probable start up date would be invaluable.
