She has demonstrated capability in leading and delivering safety-critical assurance programs across complex Communication Based Train Control (CBTC) signalling projects for major rail networks in Australia and internationally.

With deep expertise across the full V-cycle of rail safety assurance, Silpa’s capabilities include safety assurance planning and safety case development to EN 50129, in addition to hazard analyses — Preliminary (PHA), System (SHA), Subsystem (SSHA), Interface (IHA) and Operability & Support (OSHA) — and migration hazard analysis across project phase transitions. She is experienced in residual risk identification, safety requirements management and traceability in IBM DOORS, stage gate reviews and independent safety audits.

Silpa has also led RAMS programs across multiple international rail signalling projects, delivering RAM and safety assurance plans aligned to EN 50126. She also has expertise in developing Reliability Block Diagrams (RBD), MTBF analysis, Failure Mode Effects and Criticality Analysis (FMECA) at system and functional levels, Failure Reporting Analysis and Corrective Action System (FRACAS), RAM apportionment against contractual requirements, and spares calculations for liability period planning.

Silpa currently supports the Cross River Rail project in Brisbane, working across both the Rail Integration & Systems package and the Tunnels, Stations & Development package. Her work spans safety case development, hazard log management, fault tree analysis (FTA) to SIL-2 requirements, commissioning stage risk assessments, and safety in design workshops, with requirements managed in IBM DOORS.
