It is located at Bowen Mountain, near North Richmond, which is around from Sydney city. The observatory has a large rotating dome atop a concrete block building. Until 2020 it housed a 16″ ƒ/7 Dobsonian telescope, fitted with Argo Navis and ServoCAT. Then a combination of storm damage to the observatory and the COVID-19 pandemic forced the observatory to close temporarily. The society decided to take advantage of that extended break to upgrade the telescope, and commissioned the construction of a new 	Crago Observatory

It is 40 kilometres long (24 miles); 36 kilometres (22 miles) of it being dedicated high speed tracks. It was scheduled for completion by 2005 and opened in 2009. Together with the HSL 1 to the French border and HSL-Zuid to Amsterdam, the line has shortened journeys between Brussels, Paris and the Netherlands. HSL 4 is used by Thalys trains and Eurostar e320 trains. It was used by fast internal InterCity trains 	HSL 4

At Schaarbeek the line splits in two; the eastern branch continues to Liège and the German border, the northern branch towards Antwerp and the Dutch border. Between Brussels and Antwerp (47 kilometres), trains travel at 160 kilometres per hour on line 25N and then the upgraded existing line 25 (with the exception of a few segments where a speed limit of 100–120 km/h is imposed).

Trains enter the 1.5-kilometre long, two-tube tunnel past Berchem at 90 kilometres per hour. They exit the tunnel at 40 km/hour, it seems due to stability and infiltration concerns. The line surfaces at Antwerpen-Dam as line 25, and after crossing the Albert Canal, crosses the existing Antwerp-Essen line at 120 km/h.

The route parallels the E19 motorway until the border, which has required the building of several bridges. The line passes through Schoten, Brasschaat, Brecht, Wuustwezel, and Hoogstraten, before crossing the border into the Netherlands and connecting to the Dutch HSL-Zuid. Stations.

The above-ground tunnel Peerdsbos is comparable to an avalanche gallery except instead of snow it protects the trains from falling trees and the highway traffic on the E19. It was constructed as an alternative to felling parts of the nearby forest. The 'tunnel' is unique as it is covered with 16,000 solar panels. The 	HSL 4
