Amsteltram

Amsterdam tram line 25, also known as the Amsteltram, is a tram line between Amsterdam Zuid station in Amsterdam and Westwijk in Amstelveen. It officially opened on 13 December 2020 (unofficially 4 days earlier on 9 December). Work is underway to extend the Amsteltram further south to the municipality of Uithoorn. The tram line replaced metro line 51 (a.k.a. the Amstelveenlijn), a light rail line (sneltram) that ceased running south of Amsterdam Zuid station on 3 March 2019 to convert it for low-floor trams. Tram line 5 shares the stops with line 25 between Zuid station and Oranjebaan stations. Line 5 had also shared the same tracks with metro line 51, the former using low-level platforms for regular trams, and the latter using high-level platforms (since demolished).

In November 2023, the GVB planned to start line 25 service south to Uithoorn on 21 July 2024. The GVB was also examining the feasibility of extending line 25 service north from Amsterdam Zuid station to Amsterdam Amstel station.

The Amsteltram project website presents the route as two sections. The northern section, between Amsterdam Zuid station and Westwijk in Amstelveen, retains the Amstelveenlijn name, the suffix lijn meaning line. The section south of Westwijk to Uithoorn, phase 2 of the project, is called the Uithoornlijn. News releases sometimes refer to tram line 25 as the Amstelveenlijn, given that it almost completely follows the former metro line 51 route south of Station Zuid through Amstelveen. Out of five names proposed for the line, Amsteltram received a plurality of votes from a group of almost 2,500 local residents. Later, the line received its line number. IJtram (line 26) is another Amsterdam tram line with both a name as well as a number.
