    "description": "<p>Speed Optimization is a means of improving the geometric alignment, infrastructure and<br>\nconstruction materials and structure performance during the working cycles under some manufacturing,<br>\noperational and failure conditions as well as cost limitations.<br>\nThe new Ethiopian national railway network design speed is about 120Km/h which is too low when<br>\ncompared with some developed countries rail speed. Construction of new high speed line needs huge<br>\ninvestment that may not be viable for a developing country like Ethiopia and optimization of existing line<br>\nusing different techniques is the available option. The major anticipated problems/demand behind for<br>\nhigh speed for the country national rail network and Addis Ababa &ndash; Adama line in particular are for that<br>\nit is Competitive with toll road of same speed, located along the development axis area of Ethiopian<br>\neconomy, located along country&rsquo;s industrial zone highly polluted by industry emission, national image<br>\nbuilding, attracting investor and delay of freight at sea port.<br>\nOptimization of speed were done by enquiring and analyzing existing track geometry and track super<br>\nstructures, construction materials and other speed related parameters to identify restrictive sections and<br>\nthe maximum allowable speed of the line. Geometric analysis and design were done by Bentley Inrail<br>\nsoftware in the optimization process and finite element methods were used for analyzing of track<br>\ncomponent response under optimized speed</p>",
