Mipro successfully completes the Lääne-Harju Signalling System project in Estonia 

Mipro is pleased to announce the successful completion of the Lääne-Harju project in Estonia, marking a significant milestone in the railway infrastructure sector. AS Eesti Raudtee (EVR), the client, officially started using the Centralised Traffic Control (CTC) system on the 4th of December 2023, completing the extensive project delivered by Mipro. 

Since the start of the project on the 29th of June 2018, Mipro has delivered a tailor-made turnkey project encompassing various critical components: 

  • Complete railway automation design including traction calculations to optimise the capacity of the busiest line in Estonia, the Lääne-Harju line. 
  • Introduction of a new four-aspect autoblock system, enabling the customer to reduce waiting times with shorter headways between trains. 
  • Design and construction of cable routes, covering more than 80 kilometres of track. 
  • Software design of interlocking and autoblock systems, integration of audio-frequency track circuits and Automatic Protection System for Locomotives and Vehicles (ALSN). 
  • Turnkey delivery of modular buildings for signalling equipment and traffic operators tailored to the client’s architectural vision. 
  • Interfacing the Mipro signalling system with three adjacent relay-based and microprocessor-controlled interlockings.  
  • Automation design for 20 level crossings, including calculations of operating conditions. 
  • Installation and implementation of the level crossing equipment into the signalling system. 
  • Acquiring SIL-4 and AsBo functional safety certificates for the implemented systems. 
  • Successful on-site implementation of the Train Management System (TMS) and the Centralised Traffic Control (CTC) system on-site, with no interruption to train traffic. 
  • Training the client’s operations and maintenance staff to manage the new system. 

Despite challenges such as track reconstruction, concurrent railway traffic, and external geopolitical events such as the COVID-19 pandemic and Russia’s actions in Ukraine, Mipro and Mipro Eesti successfully delivered their commitments. The company expresses its sincere gratitude to the entire Mipro team and partners who contributed to the completion of the Lääne-Harju project. 

“The main goal of the Lääne-Harju railway development project was the reconstruction of the western railway lines Tallinn–Keila–Paldiski, Klooga–Kloogaranna and Keila–Riisipere–Turba to increase the capacity of the railway, raise the level of safety, and make the management, operation, and use of the railway as efficient as possible. We are happy to have achieved this goal despite the problems and challenges encountered. We acknowledge the professional attitude of Mipro, where the resolution of disagreements did not interfere with the progress of the works.”, commented Board Member-Technical Director of AS Eesti Raudtee Arvo Smiltinš.  

Commenting on the accomplishment, Margus Tali, Country Manager of Mipro Eesti, said, “The Lääne-Harju project was particularly challenging, with work carried out amidst operational railway traffic and track reconstruction. The commitment and dedication of the Mipro team and our valued partners and client’s team were instrumental in overcoming these challenges. We are thankful for their unwavering support and look forward to continuing our collaboration on current and future projects in Estonia and internationally.”
