INNOVATION IN RAIL AND TRANSIT
Norfolk Southern Corporation
Infrastructure change Management system
Eastern united States
norfolk Southern railway operates approximately 20,000 route miles in the
eastern United States, serves all major container ports, and provides vital
connections to other rail carriers. The $19 million Infrastructure change
management System (IcmS) enables the company to assess, evaluate, and
make decisions regarding its rail, assets, and property. System success was
contingent on accurate, current, and complete data.
IcmS development began with liDAr surveys of the rail network to generate
a geospatial database. Handheld GpS units now record and track a majority
of the 4,000 annual field changes, which are then uploaded to GIS servers.
microStation, Inroads, and Bentley map allow seamless updating of geographic
and attribute information. project Wise facilitates data flow between multiple
platforms. reduced data processing and overhead costs contributed to
first-year savings of $500,000.
promon engenharia developed an earth-moving project for a 9-kilometer section
of the railroad branch line supplying raw materials to a steel mill in rio de
Janeiro, Brazil. Soil conditions were complicated by the predominant presence
of organic soil, proximity to the sea, and presence of water in the terrain. In
addition, the freight train traffic carrying iron ore required earthworks that
minimized the effects of soil settling.

Rio De Janeiro, Brazil
The solution was a landfill with sufficient dimensions to house the railroad
superstructure and rainwater drainage system. The earthworks covered an
area of 181,000 square meters and moved a volume of 260,000 cubic meters.
Inroads was used to quickly analyze different alternatives and determine the
quantities of materials and services with high precision. Design changes were
easy to accommodate.
