Railway geometry is designed with a specialized application running within a CAD program

MicroStation CAD platform

Generates, manipulates and prints graphics Displays aerial images, backgrounds Layer drawings into design plans

InRail or Geopak Design Software

Intelligent “brains & math” behind graphics Ties track alignment and profile geometry to graphics Stores elevation and terrain model data for existing ground and proposed subgrade surfaces Copyright C. Tyler Dick, 2012 – All Rights Reserved 3

Early days of computing, method of math processing leads to efficiency in certain areas MicroStation for large spatial civil projects AutoCAD for detailed mechanical design Many State DOTs adopted MicroStation Railways and consultants did the same Some structures work with AutoCAD, used for rail design in states with “AutoCAD DOTs” MicroStation and AutoCAD interfaces converging over time… MS v8i offers complete cross-functionality Copyright C. Tyler Dick, 2012 – All Rights Reserved 4

Bentley InRail is a specialized version of the InRoads highway design software 95% of the commands and functions are the same Same workflow InRail offers additional capability for turnouts, superlevation, rail design criteria

Aerial and ground survey Geotechnical field investigation Track design

Horizontal and vertical geometry

InRail

Subgrade, earthwork and basic drainage Culverts and special ditches Roadway crossings and signage

Bridge and facilities design support

Survey

Contours and topo information provided in AutoCAD or MicroStation format Aerial images may also be provided

Use InRail and survey drawing to create 3D model of existing ground

Detailed Topo Preliminary Route Horizontal Alignment DTM Grades OK?

Vertical Alignment (Profile) Typical Section Balanced?

Preliminary Subgrade Earthwork Quantities Preliminary Limits of Cut and Fill Preliminary ROW Final Geometry (H&V) In ROW?

Final Geometry DTM & Typical Section Template Corridor & Preliminary Earthwork Model Set Special Ditch Profiles Detailed Earthwork Model Final Limits of Cut and Fill In ROW?

Detailed earthwork model and DTM combined into proposed terrain Drainage area analysis determines flows and culvert locations Culverts sized using hydraulic analysis programs outside CAD

Roadway crossings

Layout of panels, protection devices Horizontal and vertical reconstruction Culverts to carry ditches under roadways

Locate signage, derails, bumping posts Coordinate with bridge and/or facilities designers

Railway geometry and earthwork sections

Quantities & Cost Estimates



Standard CAD tools used to create sheets from rail design program output

When trains become tangled RTC will rewind, make changes and attempt to resolve The model will fail if it is unable to resolve complicated conflicts

“The difference between RTC and the human is that RTC solves the dispatching problem on a much larger scale: greater distances and longer periods of time

Goal is for 28 days 7 days warm up 14 days statistical period 7 day cool down Multiple random seeds Randomize train departure times Set by train type Intermodal trains [-0:15,+0:30] Merchandise Coal [-0:30,+1:00] [-2:00,+4:00] Copyright Samuel L. Sogin, 2012 – All Rights Reserved 42
