  1. Bentley Rail Update Richard W. Bradshaw Director of Development – Rail Design

  2. Background Just a bit of background on Bentley Rail Track

  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

  4. Bentley Rail Track offers… • 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

  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

  6. Alignment Enhancements Horizontal and vertical alignment enhancements for rail design

  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

  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

  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

  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

  11. Cant / Superelevation Design Specialized geometry for track cant / superelevation

  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

  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

  14. Cant Alignment Editor • Creation based upon • Equilibrium equations • Alternate speed • User defined tables

  15. Turnouts Specialized geometry that conforms to well defined bending rules

  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

  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

  18. Create Turnout • Consolidated and minimized functionality differences • Interface changes based upon library • Create from the interface or interactively

  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!

  20. Turnout Connection Editor • Used for more advanced geometric constructions • Crossovers • Sidings • Editing an existing construction • Maintains rules and relationships!

  21. Design Checking Detailed design checking based upon simple built-in rules to specific comprehensive railway rules.

  22. Built in Design Checking • Cant Alignment Editor includes basic parameters for design checking

  23. Turnout Design Checking • Check for overlapping turnouts, turnouts in vertical curves, etc.

  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

  25. User Interface Along with changes discussed in the Geometry Update, lets look at rail specific changes.

  26. Additional Command Consistency • View Horizontal & Vertical Regression Points • Additional content • Other points of interest • Combined horizontal & vertical slews

  27. Additional Command Consistency • Switch Height Plan

  28. Additional Command Consistency • Turnouts

  29. Additional Interface Changes • Smaller Dialogs • Moved buttons to right-click popup menus • And to avoid user panic, an Alert has been added!

  30. Configurable List View & Dialog Resizing • Right click in title and select data of interest • Cant Alignment Editor • Edit / Review Regression Points • Check Integrity

  31. Less Clutter • Eliminated tabbed dialogs • Moved buttons to right click context sensitive pop-up menus

  32. Localizations Country specific enhancements to increase productivity

  33. Network Rail Localizations • Display and annotation of S&C in accordance with Network Rail requirements • Unlikely scalable to others!

  34. ProRail Localizations • Display and annotation in accordance with ProRail requirements • View Plan is specific to ProRail • View Track Centers is scalable to others!

  35. Italian Railway Localizations • Display and annotation in accordance with Italian Railway requirements • Unlikely scalable to others, but tabling sparks future development requirements!

  36. Other Cant Rules • Integrating other rules into the system

  37. Austrian Railway • Reading data from Plasser & Theurer’s EM-SAT geometry measurement system • Advanced long chord measuring resolved to real world coordinates!

  38. Swept Path Analysis New functionality for the creation of vehicle swept paths

  39. Swept Path Analysis • New functionality for the creation of swept path / vehicle envelopes • Results can be • Horizontal projection only • Interactive or • 3D mesh • Up to 3 vehicles in tandem • Uses horizontal, vertical and cant geometries

  40. Vehicle Library • Manages an XML based file of vehicles • ..\Bentley Rail Track V8.11\data\metric\swept path vehicles.xml • Original data is 3D graphics

  41. Vehicle Definition • A selective / interactive import from .dgn • Bogie points • Optional articulation points • Front, middle & rear sections

  42. Horizontal Project Only

  43. Interactive

  44. 3D Mesh or Surface

  45. Bentley Rail Overhead Line A new product for the creation of overhead line equipment for electrified railways

  46. Overhead Line Design Process

  47. Starting with Bentley Rail Track • Create a network model from • Bentley Rail Track geometry • LandXML • System settings • System settings & design rules • Create • Reference lines • Wire runs • Foundations, Masts & cantilevers and other equipment • Perform engineering calculations based upon design rules • Resulting in a Rail Information Model

  48. Resulting in • Textual data • Graphical data • Plan View • Cross Section View

  49. And more details • Graphical data and • Non-graphic data
