There were "open tube" days in 1975 showcasing the station, which was the first time the public got access to the underground tunnels of the metro system.

The station, opened to metro traffic on 11 October 1980, has an island platform of 180 metres (590 ft) and two halls with a total of five entrances.

The station was designed by two architects from the Government of Amsterdam: Ben Spangberg and Sier van Rhijn [nl].

[3] Between Waterlooplein station and Weesperplein, the line makes a turn as the following curve from Nieuwmarkt to Amsterdam Centraal would have been too tight otherwise.

[4] In a 1968 metro plan released by the information office of the municipality, the station was called Stadhuis instead of Waterlooplein.

Many of its residents were deported and later killed during World War II, leaving a significant amount of the houses around the square in a bad condition.

[12] The first caisson at Waterlooplein was lowered in January 1972, which immediately resulted in delays as it hit a previously unknown wall 8 metres (26 ft) under ground dating back to the 16th century.

[14] From August to October 1975, an "open tube" event was organized inside the station, which was the first time that locals were able to see what the metro system of the city would look like.

"[26] In April 2017, the Gemeente Vervoerbedrijf started to play music through the speakers of underground metro stations as a test.

[27] Artists were invited by officials for artwork inside the stations on the East Line, with the exception of Weesperplein and Bijlmer.

[28] Waterloo by Willem Sandberg consists of blue and red letters on the platform walls spelling out the name of the work.

[21] Located on one of the station halls, Sporen van verlichte voetstappen by Dirk Müller is made up of several plexiglass plates of footsteps that leave a trace on the floor which continues on to a wall.
