Lower Silesian Agglomeration Railway (Polish: Dolnośląskie Koleje Aglomeracyjne) is a suburban rail network for the Wrocław agglomeration, covering approximately 350 km of mostly electrified double-track lines within the PKP network. Since 2009, Wrocław's authorities have been developing the system, operated primarily by Polregio and the regional Koleje Dolnośląskie company. The initiative addresses urban growth, insufficient public transport, suburban migration, traffic congestion, and air pollution.

Key milestones include reopening the Trzebnica line (2009), revitalizing the Jelcz Miłoszyce line (2021), and the integration of the Urbancard transit pass for use on suburban trains within the city (2024).^[2]. The system is informally operational, with new stations (e.g., Wrocław Różanka) and increased train frequencies. Formal branding and organization are pending, with expansions like "Park and Ride" facilities supporting its growth. The name "Dolnośląskie Koleje Aglomeracyjne" was adopted in December 2021.^[3]
