Transport in Bulgaria is dominated by road transport. As of 2024, the country had 879 kilometers of highways and another 117 km under construction. The total length of the network is almost 40,000 km, divided nearly in half between the national and the municipal road network. In addition, there are 57,000 km of streets. Buses play a significant role in long-distance public transport, coaches are operated by private companies. The capital Sofia has three major national bus terminals, the Central, the Western and the Southern Terminals.
Transport in Greece has undergone significant changes in the past two decades, vastly modernizing the country's infrastructure and transportation. Although ferry transport between islands remains the prominent method of transport between the nation's islands, improvements to the road infrastructure, rail, urban transport, and airports have all led to a vast improvement in transportation. These upgrades have played a key role in supporting Greece's economy, which in the past decade has come to rely heavily on the construction industry.
Transport in Slovakia is possible by rail, road, air, or rivers. Slovakia is a developed Central European country with a well-developed rail network (3,662 km) and a highway system (854 km). The main international airport is the M. R. Štefánik Airport in the capital, Bratislava. The most important waterway is the river Danube, which is used by passenger, cargo, and freight ships. The two most important harbours in Slovakia are Komarno harbour and Bratislava harbour.
Switzerland has a dense network of roads and railways. The Swiss public transport network has a total length of 24,500 kilometres and has more than 2600 stations and stops.
Rail transport in Australia is a component of the Australian transport system. It is to a large extent state-based, as each state largely has its own operations, with the interstate network being developed ever since Australia's federation in 1901. As of 2022, the Australian rail network consists of a total of 32,929 kilometres (20,461 mi) of track built to three major track gauges: 18,007 kilometres (11,189 mi) of standard gauge, 2,685 kilometres (1,668 mi) of broad gauge, and 11,914 kilometres (7,403 mi) of narrow gauge lines. Additionally, about 1,400 kilometres (870 mi) of 610 mm / 2 ft gauge lines support the sugar-cane industry. 3,488 kilometres (2,167 mi), around 11 percent of the Australian heavy railways network route-kilometres are electrified.
The Australian state of New South Wales has an extensive network of railways, which were integral to the growth and development of the state. The vast majority of railway lines were government built and operated, but there were also several private railways, some of which operate to this day.
The Adelaide rail network is a metropolitan suburban rail system serving the city of Adelaide, South Australia, Australia. It consists of 89 railway stations across 7 lines, which served a patronage of 15.6 million people over the year 2018-19. Keolis Downer under contract from the Government of South Australia operates the Adelaide suburban rail system. The operations are set to be handed back to the hands of the public by January 2025.
Australians generally assumed in the 1850s that railways would be built by the private sector. Private companies built railways in the then colonies of Victoria, opened in 1854, and New South Wales, where the company was taken over by the government before completion in 1855, due to bankruptcy. South Australia's railways were government owned from the beginning, including a horse-drawn line opened in 1854 and a steam-powered line opened in 1856. In Victoria, the private railways were soon found not to be financially viable, and existing rail networks and their expansion were taken over by the colony. Government ownership also enabled railways to be built to promote development, even if not apparently viable in strictly financial terms. The railway systems spread from the colonial capitals, except for a few lines that hauled commodities to a rural port.
Rail transport in the Australian state of South Australia is provided by a number of railway operators who operate over the government-owned railway lines. The network consists of 1435 mm standard gauge links to other states, the 1600 mm broad gauge suburban railways in Adelaide, a freight-only branch from Dry Creek to Port Adelaide and Pelican Point, a narrow-gauge gypsum haulage line on the Eyre Peninsula, and both copper–gold concentrate and coal on the standard-gauge line in the Adelaide–Darwin rail corridor north of Tarcoola.
Transport in Melbourne, the state capital of Victoria, Australia, consists of several interlinking modes. Melbourne is a hub for intercity, intracity and regional travel. Road-based transport accounts for most trips across many parts of the city, facilitated by Australia's largest freeway network. Public transport, including the world's largest tram network, trains and buses, also forms a key part of the transport system. Other dominant modes include walking, cycling and commercial-passenger vehicle services such as taxis.
Rail gauges in Australia display significant variations, which has presented an extremely difficult problem for rail transport on the Australian continent since the 19th century. As of 2022, there are 11,914 kilometres (7,403 mi) of narrow-gauge railways, 18,007 kilometres (11,189 mi) of standard gauge railways and 2,685 kilometres (1,668 mi) of broad gauge railways. In the 19th century, each of the colonies of Australia adopted their own gauges.
Transport in Sydney is provided by an extensive network of public transport operating modes including metro, train, bus, ferry and light rail, as well as an expansive network of roadways, cycleways and airports. According to the 2006 census, in terms of travel to work or study Sydney has the highest rate of public transport usage among the Australian capital cities of 26.3% with more than 80% of weekday trips to/from Central Sydney being made by public transport. According to the New South Wales State Plan, the state has Australia's largest public transport system. The public transport network is regulated by Transport for NSW.
Transport in Brisbane, the capital and largest city of Queensland, Australia, is provided by road, rail, river and bay ferries, footpaths, bike paths, sea and air.
The earliest trams in Australia operated in the latter decades of the 19th century, hauled by horses or "steam tram motors". At the turn of the 20th century, propulsion almost universally turned to electrification, although cable trams lingered in Melbourne. In cities and towns that had trams, they were a major part of public transport assets.
The rail network of Melbourne, Australia, has a significant number of railway lines and yards serving freight traffic. Rail transport in Victoria is heavily focused on Melbourne, and, as a consequence, much of the state's rail freight passes through the metropolitan network.
Transperth is the public transport system for Perth and surrounding areas in Western Australia. It is managed by the Public Transport Authority (PTA), a state government organisation, and consists of train, bus and ferry services. Bus operations are contracted out to Swan Transit, Path Transit and Transdev. Ferry operations are contracted out to Captain Cook Cruises. Train operations are done by the PTA through their Transperth Train Operations division.
The John Holland Group is an infrastructure, building, rail and transport business operating in Australia and New Zealand. Headquartered in Melbourne, it is a subsidiary of China Communications Construction.
Keolis Downer is a joint venture between Keolis, the largest private sector French transport group, and Downer Rail, an Australian railway engineering company, that operates bus and tram services in Australia.
Electrification of Australian railways began with the Melbourne and Sydney suburban lines. Melbourne suburban lines were electrified from 1919 using 1,500 V DC. Sydney suburban lines were electrified from 1926 using the same system.
Transport in South Australia is provided by a mix of road, rail, sea and air transport. The capital city of Adelaide is the centre to transport in the state. With its population of 1.4 million people, it has the majority of the state's 1.7 million inhabitants. Adelaide has the state's major airport and sea port.
