Tallinna Linnatranspordi Aktsiaselts (TLT) is a public transport company owned by the City of Tallinn. TLT was formed on 18 July 2012 as a result of the merger of two longstanding passenger transport companies – the Tallinn Bus Company (Tallinna Autobussikoondise AS) and the Tallinn Tram and Trolleybus Company (Tallinna Trammi- ja Trollibussikoondise AS) – as a provider of public transport services. TLT is primarily engaged in providing bus, trolleybus, and tram services on routes within the integrated ticketing system of Tallinn.
