Detailed Engineering of AST2 Rail Yard for Industrial Chemical Plant in Corunna, Ontario

Technicas Reunidas Canada hired SYSTRA Canada to perform a detailed engineering study for a future rail yard for a chemical plant in Corunna, Ontario, Canada.

The mandate consisted of:

  • Rail Yard Substructure Engineering (to top of sub-ballast), including grading, access roads, ditches and drainage of access roads;
  • Rail Yard Superstructure Engineering (from ballast to top of rail).


SYSTRA Canada’s mandate included:

  • Trackwork Design: Conceptual rail geometry and verification of design criteria; Detailed track geometry, including switches, crossings, and turnouts; General track configuration (rail profile, sleepers); Interface design to existing railway; Estimation of quantities.
  • Operational Requirements: Validation of loading/unloading rail barn layout; Validation of rail car wash barn layout; Interface design with rail car wash barn; Interface design with railcar loading/unloading.
  • Drainage Design: Sub-grade and sub-ballast drainage and connection to general ditch arrangement; Open ditch geometry and alignment for internal roads and rail yard groups; Interface with general drainage design of the AST2 project.
  • Interface Design Management: Verification of interface subsystems; Sub-grade, ballast and sub-ballast study; Identification of necessary removals; Material specifications for construction; Structural design to support infrastructure.
  • Safety Case Analysis: Analysis of temperature effects in rail tracks; Analysis of potential train derailment cases; Rail fastening system specifications (to support above).
