Amateur Survey teams under the direction of the engineers closely led the work
Amateur crews and marked where and by how much hills would have to be cut and depressions filled or bridged.
Coordinators made sure that construction and other supplies were
provided when and where needed, and additional supplies were ordered as the railroad construction
consumed the supplies. Specialized bridging, explosive and tunneling teams were assigned to their specialized jobs.
The majority of the Union Pacific track across the Nebraska and Wyoming
territories was built by veterans of the Union and Confederate armies,
Church of Jesus Christ of Latter-day Saints, landed contracts with the Union
Pacific that offered jobs for around 2,000 members of the church with the
hope that the railroad would support commerce in Utah.
than others, so the specialized teams were sent out ahead by wagon trains
with the supplies and men to get these jobs done by the time the regular
track-laying crews arrived. Finance officers made sure the supplies
were paid for and men paid for their work. An army of men had to be
coordinated and a seemingly never-ending chain of supplies had to be
provided. The Central Pacific road crew set a track-laying record by laying
10 mi (16 km) of track in a single day, commemorating
the event with a signpost beside the track for passing trains to see.
In addition to the track-laying crews, other crews were busy setting up
stations with provisions for loading fuel, water and often also mail,
passengers and freight. Personnel had to be hired to run these stations.
Maintenance depots had to be built to keep all of the equipment repaired
and operational. Telegraph operators had to be hired to man each station
to keep track of where the trains were so that trains could run in each
direction on the available single track without interference or accidents.
Sidings had to be built to allow trains to pass.
