Question: Which Australian building, distinguished by its three white geometric dome roofs, was built over land where the Jubilee railway line once ran?
Context: The Salsette–Trombay Railway (also known as the Central Salsette Tramway) was a standard gauge railway line on the island of Salsette in the city of Mumbai (Bombay), India.  The line was opened in 1928 by the Great Indian Peninsular Railway under the Bombay Improvement Trust which called for ""the opening up of a Railway line running West to South-east and linking up the Andheri and Kurla stations" to "render available for building purposes vast tracts of land sufficiently close to the city.""  Hence the line linked Andheri in the north with the village of Trombay in the east.  The rail line was about 13 km long.  During weekends, the line was frequented by picnickers who used to travel to Trombay to buy toddy or palm liquor. Minnipa is a small town serving the local grain growing community located on South Australia's Eyre Peninsula.  The area around the town was first settled in 1878 but it wasn't until the arrival of the railway line in 1913 that any kind of township developed.  When the railway was opened to Minnipa on 5 May 1913, the town consisted of two tents.  Development of the surrounding districts followed the railway, and accelerated after the opening of the water pipeline from the Tod River scheme in 1925.  By 1960, Minnipa was the major railway centre between Cummins and Thevenard.  Before the construction of the Tod River scheme and its network of pipelines, tanks were constructed at many locations to catch the runoff from the granite outcrops which are a feature of the landscape.  The earliest of these were constructed at Minnipa Hill in 1914 by the South Australian Railways.  These historic tanks were reconditioned in the 1990s and fitted with new roofs to provide a standby water supply for Minnipa. The Stephen Decker Rowhouse is a historic multiple residence in the Columbia-Tusculum neighborhood of Cincinnati, Ohio, United States.  Built in 1889, it occupies land that was originally a portion of the wide vineyards of Nicholas Longworth.  In 1869, after his death, Longworth's estate was platted and sold to builders who constructed a residential neighborhood along Tusculum Avenue.  One of the most unusual buildings was the Decker rowhouse, which features multiple distinctive Victorian elements.  Chief among these is the ornamentation on the porch roofs: they include gabled rooflines and beveled corners supported by multiple spindles.  Connecting these porch roofs are low normal roofs, which primarily protect the recessed entrances to the houses.  Elsewhere, the houses feature double-hung windows, imbricated shingles on the gables, and arcades of Gothic Revival panelling, and numerous ornamental circles inscribed within squares.  Taken as a single building, the rowhouse measures two bays wide and eighteen bays long; it is of frame construction and two stories tall.  Rated "outstanding" by an architectural survey in 1978, it is the only rowhouse of its type in Cincinnati, due to its well-preserved Victorian architecture. The Jubilee railway line is a former railway in Adelaide, South Australia.  It was built in 1887 from where the Adelaide station currently is to where the former Jubilee Exhibition Building was.  The line used an existing tunnel under King William Road which was built in 1854 to transport horses and cattle.  The tunnel is likely the origin of rumours about rail tunnels located under the city of Adelaide.  Much of the land where the line once ran has been constructed over to build parts of Adelaide University and the Adelaide Festival Centre.  There were no stations built.  No known evidence of the line remains today. The Adelaide Festival Centre, Australia's first multi-purpose arts centre, was built in 1973 and opened three months before the Sydney Opera House.  The Festival Centre is located approximately 50 metres north of the corner of North Terrace and King William Street, lying near the banks of the River Torrens and adjacent to Elder Park.  It is distinguished by its three white geometric dome roofs and its plaza consisting of lego block-like structures to the south and lies on a 45-degree angle to the city's grid.  It is the home of South Australia's performing arts.  The Adelaide Festival Centre replaced the City Baths, which stood in this spot for many decades. The Worcester, Bromyard and Leominster Railway was a 24.5 mi single track branch railway line, that ran between a junction near on the West Midland Railway line south of Worcester (present day Cotswold Line) to the Shrewsbury and Hereford Railway line south of . Rail transport was first introduced in Burma in May 1877, when Lower Burma was a colony of the United Kingdom and a part of British India, with the opening of the Rangoon to Prome line by The Irrawaddy Valley State Railway.  This line, 163 miles long, tracing the course of the Irrawaddy river, was built over three years with labour imported from India, particularly from the areas affected by the Bihar famine of 1873–74.  In 1884, a new company, The Sittang Valley State Railway, opened a 166-mile line along the Sittang River from Rangoon to the town of Toungoo via Pegu.  While the Irrawaddy line was considered to be of commercial importance because it could be used to move rice from the valley to the main port at Rangoon, the Sittang line was of considerable strategic importance because of the proximity of Toungoo to the border with Upper Burma, then a part of the Ava kingdom.  This became evident at the start of the Third Anglo-Burmese War a year after the opening of the railway and during the unrest that followed the war.  The construction cost for the two lines was £1,926,666 and the railway was profitable by 1888 returning more than 5% on the capital expenditure.  With the annexation of Upper Burma, the railway was extended by 220 miles from Toungoo to Mandalay, the fallen capital of the Ava kingdom with the extended railroad opening in 1889.  Following the opening of this section, the Mu Valley State Railway was formed and construction began on a railway line from Sagaing to Myitkyina and connected Mandalay to Shwebo in 1891, to Wuntho in 1893, to Katha in 1895, and to Myitkyina in 1898.  With the opening of this railway, a continuous 724 mile railway line ran from Rangoon to Myitkyina through the Kachin Hills except for a ferry crossing of the Irrawaddy at Sagaing.  The Inwa Bridge at Sagaing, the only one across the Irrawaddy River in Burma, was opened in 1934, with two decks, one for road traffic and one for rail traffic. The Jubilee Oval was a sporting ground created in 1895 between the Jubilee Exhibition Building and the River Torrens.  It was located next to the railway station at the end of the Jubilee Exhibition Railway line, which operated from 1887-1927.  It incorporated a (banked) cycle racing track; and a new grandstand and seating on the mound were built in 1896. The Sulitjelma Line (Norwegian: "Sulitjelmabanen" ) was a railway line that ran between Finneid in the town of Fauske to the village of Sulitjelma near the border with Sweden.  The railway line was entirely inside the municipality of Fauske in Nordland county, Norway.  The line was built in 1891, over time it was lengthened until 1958 when it was connected to the Nordland Line.  It existed as a branch of the Nordland Line from 1958 until 1972 when the line was closed and removed.  The railway line followed the path of the present-day Norwegian County Road 830. The Southern Railway Depot is a historic building in Decatur, Alabama.  The depot was built in 1904–05 along the Southern Railway line.  Decatur had become a transportation hub of North Alabama by the 1870s, with its connections to the Tennessee River, the east-west Tuscumbia, Courtland and Decatur Railroad (later operated by the Memphis and Charleston Railroad and the Southern Railway), and the north-south Louisville and Nashville Railroad.  It functioned as a passenger station until 1979, when Amtrak cancelled its "Floridian" service.  The station is built of brick painted white, with quoins on the corners.  The building has a rectangular central section with narrower wings stretching along the tracks.  The central section has a hipped roof, while the wings have gable roofs; both have deep eaves with decorative brackets.  The main entrance is covered by a porte-cochère with arched openings.  The depot was listed on the National Register of Historic Places in 1980.
