Constantin Ciobanu is a Chartered Engineer, Fellow of the Permanent Way Institution and a Member of the Chartered Institution of Highway and Transportation .

Constantin has 17 years’ experience in railway track domain, including 13 years teaching and research experience as Railway Track Lecturer at the Technical University of Civil Engineering (TUCE) Bucharest and more than 10 years of experience as design engineer.

His teaching activity covered topics related to the design and maintenance of railway lines and stations, tramway tracks and roads. The main teaching activities were:

  • Yearly Design Projects – railway track, formation and earthworks design of rail stations (S&C layouts) and plain line;
  • Realignment and rectification methods – Hallade and Direction Angle Diagram;
  • Continuous welded rail (CWR) track behaviour, critical rail temperature (CRT) management and stressing methods;
  • Track superstructure for high speed lines.

As University Lecturer and Assistant Lecturer, Constantin led BSc graduation design projects for railway and tramway track. For four years he was Secretary of the Bachelor Degree Graduation Commission of the Faculty of Railways, Roads and Bridges of TUCE Bucharest.

Constantin was involved in railway track research works mainly on the behavior of the continuous welded rails.

He  was assistant Lecturer for two post-university graduation courses:

  • Rectification and realignment methods  used to improve the existing track geometry.
  • Continuous Welded Rails for plain line and Switches & Crossings. Stressing methods and CWR maintenance.

These 5 week courses were part of the continuous professional development programme for the maintenance track engineers of the Romanian Railways (CFR).

Constantin led one of the main track design teams for the modernisation of the Romanian sections of the IVth Pan–European Railway Corridor (part of the Trans-European Network), being leading track design engineer and contract responsible engineer on two 100 km sections of the Corridor.

Currently working as Principal Track Engineer in United Kingdom, responsible for Permanent Way Design on various Network Rail projects from GRIP3 to GRIP5.

Key skills and experience:
– Designing and checking plain line, station layouts and S&C design, Stressing, Platform/structural gauging, track drainage.
– Both academical and practical knowledge of Railway Track Design, including track geometry for conventional and high speed lines, for ballasted and slab track.
– Experienced engineer involved in high scale multidisciplinary track infrastructure projects
