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.

The northern section, between Amsterdam Zuid station and Westwijk in Amstelveen, retains the Amstelveenlijn name, the suffix lijn meaning line.

Out of five names proposed for the line, Amsteltram received a plurality of votes from a group of almost 2,500 local residents.

After leaving Station Zuid, the line runs south along Parnassusweg, Buitenveldertselaan and Beneluxbaan (effectively the same north-south street with changes in name) in a centre reservation until Gondel, a street south of the Sportlaan tram stop.

The centre reservation keeps the tram line free of road traffic except for level crossings at major street intersections.

Three line 25 stations (Kronenburg, Zonnestein and Sportlaan) are located below street level in an underpass, thus eliminating the need for a grade crossing at a major cross-street.

[2] The Amsteltram uses low-floor trams (type 15G) manufactured in Spain by Construcciones y Auxiliar de Ferrocarriles (CAF).

R-net [nl] (short for Randstadnet) is the hallmark for high-order public transport in the Randstad; it also used on the Amsterdam Metro.

Heading south, a light-rail train would raise its pantograph, retract its third-rail shoes and switch voltage from 750V (metro) to 600V (light rail).

From Westwijk, the extension follows the old railway embankment south across Legmeerpolder to the street Aan de Zoom before curving east to Uithoorn's village centre, on the Amstel River.

The extension included a bridge over highway N201 at the south end of the embankment over Legmeerpolder, and an underpass to pass under Zijdelweg.

There are also warning lights at the stops Aan de Zoom and Uithoorn Station where riders can cross the tracks to access the desired platform.

the Amstelveenlijn), a light rail line (sneltram), ceased running on 3 March 2019 to permit the conversion of the Amsteltram for low-floor trams.

[33] Beginning 30 November, a full system test of line was conducted with trams running to schedule but without passengers.

[34] Unofficially, line 25 carried paying passengers starting 9 December 2020 during the system testing period.

However, the GVB did not provide any real-time travel information for line 25 during that early opening period.

Shuttle buses were used twice, once for a power failure at Zuid station and another due to a malfunction on a 15G tram.

)[37] In May 2022, work started to expand the Legmeerpolder tram storage yard to roughly double its size.

[38] In August 2022, work started to move the bus stop at Burgemeester Kootlaan further east along the busway in Uithoorn.

[39] Also in August 2022, work started to lay tram tracks between the streets Aan de Zoom and Randweg just south of Legmeerpolder.

During the test period, the rear tram of a two-tram train derailed at a crossover switch at the Legmeerpolder depot.
