Onderuit tram stop

Onderuit is a tram stop within the city of Amstelveen, Netherlands. The stop serves tram lines 5 and 25. Line 25, dubbed the Amsteltram before receiving its line number, opened officially on 13 December 2020, unofficially 4 days earlier on 9 December.

Before being rebuilt in 2019 and 2020, the stop used to serve both the low-floor trams of tram line 5 plus the high-floor trams of metro line 51, a hybrid metro/sneltram (light rail) service that opened in 1990. Both lines 5 and 51 shared the same pair of tracks but used separate, adjacent platforms. There were a pair of low-level platforms for line 5 and a separate pair of high-level platforms for line 51, with stairs connecting the two platform levels. In 2019, metro line 51 service south of Amsterdam Zuid station was terminated to rebuild stations to accommodate only the low-floor trams of lines 5 and 25; the high-level platforms were demolished, and the low-level platforms were lengthened to handle a coupled pair of low-floor trams.
