In 1973, in connection with the extension of the line to Mexikói út station, the line was diverted on a different route under the park. The old surface terminus at Széchényi fürdo was replaced by a new underground station on the same site, but Állatkert station was abandoned.[1][2]
The only remaining visible feature of the station and the railway it stood on is a bridge, which formerly crossed the metro line but now simply crosses a lawn. It is a very early example of a reinforced concrete bridge, designed by György Brüggemann and built by Róbert Wünsch.[2]
