RA IL SUMMI T 20 24

Infrabel Bascoup

 Turnout production plant

 Since 1912

 Design, production & assembly

 +/- 1,5 turnout per day

 Since 2016 new assembly hall for concrete sleepers

 In 2021 record of 300 turnouts in one year

RA IL SUMMI T 20 24

Infrabel Current approach and challenges

Alignment design made with Civil 3D Turnout Library made by Infrabel turnout

experts

RA IL SUMMI T 20 24

Infrabel Current approach and challenges

 Manual placement

 Manual adapting

 Manual update when new block

 Time consuming & room for errors

 No intelligence behind

RA IL SUMMI T 20 24

Current approach and challenges

 After track-layout approval -> Assembly plan for the

turnouts (blocks visibility states)

 Manual, tabels, no data

 Timeconsuming

Infrabel

Infrabel – Autodesk Collaboration The Why ?

 Government company -> bureaucracy -> changement is difficult

 Everybody working on own island with own (old) methods

 New concrete turnouts -> new design method

 Infrabel turnout know-how <-> Autodesk tool know-how

 Interoperability between specialities

Railway design – C3D Turnout tool

Flexible enough to integrate

different construction rules

Versatile enough to integrate

different types and models

Railway design – C3D Turnout tool

This file contains the catalog library, geometrical parameters of

each turnout model are defined

This file defines how your turnout its build, whether its a straight

pose, bend pose. These rules are defined by turnout type

indicated in the json file.

Q&A Sessions Further information was necessary to build and reproduce turnout behavior

Infrabel – Autodesk Collaboration The How ?

Q&A Sessions Further information was necessary to build and reproduce turnout behavior

Infrabel – Autodesk Collaboration The How ?

Belgium standards documentation :

• Schemas • Diverted line geometry • Bend behavior

Initiative content definition

Translate standards and guide lines in to an C++ expr file to build the Json Expr file Using API expressions for turnouts

Test phase : One turnout model of each type of layout was use to test compliance with Standards

Q&A Sessions Further information was necessary to build and reproduce turnout behavior

Infrabel – Autodesk Collaboration The What ?

JSON JSON EXPR

Test library with models to test accuracy and

compliance of the Json Expr

Json Expr file that works for single turnouts in

straight and bend pose

Different types of layout and diverted geometry

Multiple end of crossings per turnout

Outcomes

Avoid rework

Reduce manual workflows

Reduce overall time design

Improve user experience

New Way Of Work for turnout layout

Next Steps New Way Of Work for turnout layout

Turnout and Track Alignment design

Turnout assembly design
