  <dc:description>Speed Optimization is a means of improving the geometric alignment, infrastructure and
construction materials and structure performance during the working cycles under some manufacturing,
operational and failure conditions as well as cost limitations.
The new Ethiopian national railway network design speed is about 120Km/h which is too low when
compared with some developed countries rail speed. Construction of new high speed line needs huge
investment that may not be viable for a developing country like Ethiopia and optimization of existing line
using different techniques is the available option. The major anticipated problems/demand behind for
high speed for the country national rail network and Addis Ababa – Adama line in particular are for that
it is Competitive with toll road of same speed, located along the development axis area of Ethiopian
economy, located along country’s industrial zone highly polluted by industry emission, national image
building, attracting investor and delay of freight at sea port.
Optimization of speed were done by enquiring and analyzing existing track geometry and track super
structures, construction materials and other speed related parameters to identify restrictive sections and
the maximum allowable speed of the line. Geometric analysis and design were done by Bentley Inrail
software in the optimization process and finite element methods were used for analyzing of track
component response under optimized speed</dc:description>
