Market Drivers


OpenRail ConceptStation


What Is / Why Use OpenRail ConceptStation?

• Rapid layout by users of all backgrounds

– In-depth software knowledge not necessary

• Know financial implications early

– Project cost estimate automatically updates as design changes

• Better communication with all stakeholders

– Real-time visualization of actual design content

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…


Where we want to be…


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


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


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


Templates

• Expansive starting library provided

• Build customized templates from:

– Generic components

• End conditions, walls, etc

– Rail specific components

• Ballast, SubBallast,Rails


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


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


• 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


Vertical Clearance

Work through potentially unlimited options for optimal refinement


Quantities

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


Financial Implications

As you modify design, quantities/cost keep up with you


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.


Visualization

Real-time rendering Output Images, Videos, Live Cube

Add characters, plants, trees &

vehicles

Changing atmospheric conditions,

time (night), seasons


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)
