The extension from Közvágóhíd serves four intermediate stations before reaching the new - albeit temporary - terminus at Etele út/Fehérvári út.
Funding has already been approved for a further 1.7km extension to Etele tér adjacent to Kelenföld main line station. The project is due to be completed by 2020.
At the northern end of Line 1 another 3km extension has also been approved which will take trams to the future Aranyvölgy station on the Budapest - Esztergom heavy rail line.
Prior to the construction of the new extension, the existing section of Line 1 was rebuilt, including some turfed sections. Services are currently operated by Czechoslovakian-built Tatra T5C5 trams but by the end of the year, 12 new CAF low-floor LRVs will also be introduced. These will be the longer version of the 47 vehicles now on order from CAF, with a length of 56m, making them the longest trams in Hungary.
The extension cost Forints 27.5bn (€ 98.1m), 93.9% of which came from European Union sources.
