© 2009 Bentley Systems, Incorporated 2 | Background Just a bit of background on Bentley Rail Track

© 2009 Bentley Systems, Incorporated 3 | Bentley Rail Track is a Global Solution! Bentley Rail Track is suitable for designing –Light rail –Heavy rail –High-speed rail Steel on steel or magnetic levitation systems Bentley Rail Track has been internationalized –Available in English, German, Spanish, Chinese plus other languages Bentley Rail Track is localizable –Deliver standard turnouts –Build in railway specific design checking

© 2009 Bentley Systems, Incorporated 4 | Horizontal & horizontal alignment design –New design –Single and multi-element regression analysis for maintenance / renewals Cant / superelevation design Turnouts Also includes specialized toolsets for –Design checking –Field to design / Design to field Machine to design to machine –Light rail manufacturing –Magnetic levitation Bentley Rail Track offers…

© 2009 Bentley Systems, Incorporated 5 | Major Differences Between Road & Rail Horizontal alignment design based upon cant (i.e. superelevation) –Arc or chord definition alignments –Horizontal spiral transition types Clothoids + cubic parabola, AREMA, bi-quadratic parabola, Bloss, sinusoid, cosine and Viennese 1 to 1 relationship between the horizontal transition and the cant transition Vertical alignment design –Parabolic vertical curves –Circular vertical curves + clothoids Turnouts are a type of geometry –Multiple types (single, double and slips) –Multiple bending methodology

© 2009 Bentley Systems, Incorporated 6 | Alignment Enhancements Horizontal and vertical alignment enhancements for rail design

© 2009 Bentley Systems, Incorporated 7 | Rail Specific Additional Transition Spirals –AREMA Length along axis and chord definition US freight standard –Cubic’s Multiple definitions –Length along axis –Length along tangent

© 2009 Bentley Systems, Incorporated 8 | Regression Workflow… Pre-regression data validation Point selection and sorting –Survey data ordering is not required Curvature diagrams –Indicates approximate locations of specific elements and their types –Indicates questionable data –Inclusion of cant enhances the field data! Edit / review –Select / Regress, which is heads-up selection / auto element type determination! Reduces potential user errors & time –Quick Regression Slew diagrams and reporting

© 2009 Bentley Systems, Incorporated 9 | Quick Regression Quick horizontal regression –A first pass – automatic regression Includes lines, circular arcs and spirals Resolves long straights into multiple straights Quick vertical regression –Similar to horizontal –Includes a standard lift & a lines only option

© 2009 Bentley Systems, Incorporated 10 | Single Element Regression Enhancement Single element regression with multiple alignments –Single element regress 2 or more alignments at once –Regressed elements will be parallel / concentric to each other –Different offsets for each set of elements Enabled by right-clicking in Edit / Review Regression Points list-view Automatically occurs with Select & Regress option

© 2009 Bentley Systems, Incorporated 11 | Cant / Superelevation Design Specialized geometry for track cant / superelevation

© 2009 Bentley Systems, Incorporated 12 | Cant / Superelevation Standard international railway terminology –Equilibrium cant, applied cant, cant deficiency, etc. Units –Millimeters, millimeters / second –Inches, inches / second Calculations –Standard equilibrium equations that can be found in well known literature

© 2009 Bentley Systems, Incorporated 13 | Integrated into Horizontal Design Radius & spiral lengths based upon cant –Cant & Speed are persisted with the horizontal elements –Suggests spiral lengths Imperial & metric are slightly different –Enables design optimization

© 2009 Bentley Systems, Incorporated 14 | Cant Alignment Editor Creation based upon –Equilibrium equations –Alternate speed –User defined tables

© 2009 Bentley Systems, Incorporated 15 | Turnouts Specialized geometry that conforms to well defined bending rules

© 2009 Bentley Systems, Incorporated 16 | View Options Single, double and slips –Tangential and non-tangential turnouts Multiple bending / flexing methods to satisfy various industry standards! –Germany / Austrian –Swiss –UK

© 2009 Bentley Systems, Incorporated 17 | Turnout Library Typical Turnout Library Editor –Creation of typical turnouts (standards) The software delivers various country standards –German (heavy & light rail) –UK (113A’s & RT60’s) –Indian Railways –Dutch Railways / ProRail –Spanish (heavy & light rail) –Or we will help you to create them AREMA Alternative (US + Canada) –Familiar terminology Matches AREMA Track Manuals Delivered with the product

© 2009 Bentley Systems, Incorporated 18 | Create Turnout Consolidated and minimized functionality differences Interface changes based upon library Create from the interface or interactively

© 2009 Bentley Systems, Incorporated 19 | Create Turnout Connection Start with a single turnout and create a connection to a new turnout –A simplification to minimize using the Turnout Connection Editor for simple crossovers –Ending turnout may match the beginning turnout –Connection is linear or circular, software makes the determination!

© 2009 Bentley Systems, Incorporated 20 | Turnout Connection Editor Used for more advanced geometric constructions –Crossovers –Sidings Editing an existing construction Maintains rules and relationships!

© 2009 Bentley Systems, Incorporated 21 | Design Checking Detailed design checking based upon simple built-in rules to specific comprehensive railway rules.

© 2009 Bentley Systems, Incorporated 22 | Built in Design Checking Cant Alignment Editor includes basic parameters for design checking

© 2009 Bentley Systems, Incorporated 23 | Turnout Design Checking Check for overlapping turnouts, turnouts in vertical curves, etc.

© 2009 Bentley Systems, Incorporated 24 | More Comprehensive Design Checks Includes –CEN Standards –Austrian Rail –Danish Rail –ProRail / Dutch Rail –German Rail –Italian Rail –Transrapid Execute as you design –Interactive + passive Execute as a post-design process –Ideal for checking a consultant’s design Written to match the railway’s requirements
