Initial Concept Design Options and Costing
Rail Engineer High level of cost variance, up to 50%.
Cost calculations for rail projects are done using approximate methods that has a very low level of certainty. Ex: Cost for unit length of track.
More Efficient Prototyping
Different options can be considered with ease
Identification of greater cost savings

Current workflows…
14 | WWW.BENTLEY.COM | © 2018 Bentley Systems, Incorporated
Where we want to be…
15 | WWW.BENTLEY.COM | © 2018 Bentley Systems, Incorporated
Intuitive Workflow
• Clean, easy to use interface– Only applicable tools for rail conceptual design & visualization
• 3D design/modeling made easy– Semi-automation of typically complicated design decisions
• Program works just as you work– Assemble Existing Data
– Layout Conceptual Rail Design
– Analyze results & adjust design accordingly
– Present to stakeholders• Design adjustments are so fast & easy, the can be done live, together with stakeholders
– Once approved/ready to proceed, take content ahead to detailed design
16 | WWW.BENTLEY.COM | © 2018 Bentley Systems, Incorporated
Assemble Existing Data
• Multiple options:
– Import from GeoCoordination Services
• Imagery, terrains & OpenStreet Map (OSM) content
– Import from local files already obtained
• In addition to that above, GIS data & DGN files
– Stream imagery from Bing
– Attach Reality Model published from Bentley ContextCapture

Concept Design and Existing Infrastructure
Rail Engineer High uncertainty in conceptual design
Limited information available from the concept model, maybe just the track model without other project disciplines or multiple software used to create a concept design (with limited compatibility)
Quick and easy concept design allows for optioneering
Identification of risks at the earlier stages
Interaction of the design with the existing infrastructure and other project stakeholders

Conceptual Rail Design
• Rail Placement Tools
• Furniture Placement Tools
• Structure Placement Tools
• Measure Tools
23 | WWW.BENTLEY.COM | © 2018 Bentley Systems, Incorporated
Horizontal Rail Layout
• Initial layout with various tools (and design parameters):– Template
– Classification
– Design Speed• Used to select minimum curves and
to calculate superelevation
– Profile (best fit vs simple tangent)
• Yard tool– Creates level base surface
– Subsequent use by offset track tool for yard/station design
24 | WWW.BENTLEY.COM | © 2018 Bentley Systems, Incorporated
Templates
• Expansive starting library provided
• Build customized templates from:
– Generic components
• End conditions, walls, etc
– Rail specific components
• Ballast, SubBallast,Rails

27 | WWW.BENTLEY.COM | © 2018 Bentley Systems, Incorporated
Connect Rail Network
• Connect adjacent tracks with:– Turnouts
• Extensive turnout library using precise turnout definitions and crossing angles
– Fit turnout• Automatic placing of turnouts on track
intersections of two or more tracks
– Secondary alignments trimmed
– Crossovers• Places 2 turnouts and joining diagonal
tracks
• Different turnouts can be selected for the first and second turnout
28 | WWW.BENTLEY.COM | © 2018 Bentley Systems, Incorporated
29 | WWW.BENTLEY.COM | © 2018 Bentley Systems, Incorporated
Rail On/In Structures
• Bridge– Select template for deck geometry
– Uses Bentley LEAP engine
– Comprehensive library• Superstructure, Substructure
– Simple 2 point placement
• Tunnel– Inherits template
– Parameters can be changed after placement• Including template
– Also simple 2 point placement

32 | WWW.BENTLEY.COM | © 2018 Bentley Systems, Incorporated
• Masts & Portals– Extensive library of structures
– Double and single cantilevers• Automatic push & pull configuration
and stagger based on track geometry
– Granular parameters allow in-depth control of placement
• Automatic (multiple) or manual (single)
– For portals, select individual tracks to be electrified
• Add Wires & Overlaps manually as needed
Overhead (Catenary) Electrification Systems (OLE/OCS)

Analyze and adjust design accordingly
• Cross section review allows for quick design confirmation
• Easily analyze critical design requirements such as vertical bridge clearance
– Know early in the design process and easily adjust as needed
• Prevent financial implications from surprising you late in the design process
– Best approach to try to reduce them is not always straightforward
– Make design modifications and find out immediately
• Live, in-person with stakeholders

Concept Design and Existing Infrastructure
Rail Engineer High uncertainty in conceptual design
Missing information about the constraints, bridges,utilitiesand asset information… results in costly rework and delays in the later stages.
Identification of risks at the earlier stages
Interaction of the design with the existing infrastructure
Bridge clearances
Crossings

Financial Implications
As you modify design, quantities/cost keep up with you
44 | WWW.BENTLEY.COM | © 2018 Bentley Systems, Incorporated
45 | WWW.BENTLEY.COM | © 2018 Bentley Systems, Incorporated
Convey Concept to Third Parties
Rail Engineer How to convey the new rail concept to other parties.
Traditional 2D layouts or triangulation/contour models are confusing for non project members/public viewing.
Lumen RT visualization creates a realistic view of the proposed scheme.

Utilising Concept Design in Detail Design
Rail Engineer Problems in transition from conceptual design to detail design.
In many cases the data from conceptual design is completely disregarded due to low quality and a complete re-work is done. Also there is loss of information in this handoff process.
Easier handoff between conceptual design and detail design

Summary
• Assemble and utilize existing content quickly and easily
• Explore more alternatives in the same amount of time
• Identify high-cost items and potential issues earlier in the process
• Move from idea to 3D faster than ever (you don’t have to be an engineer or CAD expert)
• Instantaneously render with the actual engineering model (without being a visualization expert)
