ballast subballast geometric design

Job ID: 32380203

Budget: $30 – $250 USD

For the project you need to:
• Find the right R for each horizontal curve.
• Draw one typical cross-section for tangent segments (AUTOCAD)
• Draw a cross section for each curve showing the superelevation (AUTOCAD)
• Find the required HP for following vertical profile assuming max train weight is 1800 tonne.
• Operation scheduling
• Depth for ballast + suballast
Design information
• Traffic : mixed (Fright 110 km/hr , Passenger 250 km/hr)
• Headway : 5 mins
• Single track
• Freight trains start 30 min earlier than passenger trains
• Annual Tonnage : 120 MGT (short ton)
• Heaviest load comes from six axle locomotive with total weight of 190 tonne
• Es = 14 MPa
• Eb= 280 Mpa
• Distance from the top of the subgrade to rigid boundaries = 1.5 m
• Type of soil = ML
• D = 840 mm
• K = 6000 lbs/in/in
• σs = 90 kpa
• Rail size = UIC 60
Project report layout:
The project report should be as professional as possible you need to include a section for each
part of the design and explain the methods used for the design. The report should include sections
such as
• introduction
• design standards
• ballast design
• subballast design
• geometric design
• required HP
• operation timetabling
