AECOM has presented the first outcomes of the study on Integration of Rail Baltica railway line within the Riga central multimodal public transportation hub – elaboration of the technical solution, during a meting with Riga City Architectural Board. The study aims to deliver a feasible engineering and urban building solution for Riga Central Multimodal Public Transportation Hub, by ensuring the mutual integration of two railway systems, public transportation and individual mobility solutions within a single transport hub.
The company has elaborated various scenarios for Riga central multimodal public transportation hub, following a comprehensive passenger, pedestrian and traffic flow data collection and analysis, modelling and forecast for a period of 10-40 years, macrolevel and microlevel modelling within the transport hub with the identification of Rail Baltica railway infrastructure (tracks, platforms, structures, and other infrastructure) engineering and technology solutions and connections with other transport modes.
The minimum intervention scenario of the new multimodal hub includes an elevated railway station connected to existing Riga Central Station, high platforms for increased accessibility, new longitudinal canopies for covering the platforms. Some coach platforms will be removed due to Rail Baltica tracks and the area will be reconfigured. No action will be taken in regarding 13. janvāra Street – Flee Market.
The maximum intervention scenario, which is more complex, foresees an elevated railway station-bus interchange at street level (removing the embankment) and basement car parking, as well as high platforms for increased accessibility, new longitudinal canopies for covering the platforms. New tram Line through Dzirnavu iela: adaptation to existing underpass in Dzirnavu iela (clearance, width, rail requirements), new provision of electrical system for the tram line.
According to Arnis Kākulis, AECOM Regional Director in the Baltic states, the preliminary cost estimation for implementing maximum intervention scenario range from EUR 96 million to EUR 120 million, of which 83% would be covered by EU funds.
The Latvian Ministry of Transport together the project stakeholders are expected to take a decision in regarding which solution to implement, before the 29th of December 2015.
