Vietnam Railways is the state-owned operator of the railway system in Vietnam. The principal route is the 1,727 km (1,100 mi) single-track North–South Railway line, running between Hanoi and Ho Chi Minh City. This was built at the metre gauge in the 1880s during the French colonial rule. There are also standard gauge lines running from Hanoi to the People’s Republic of China, eventually leading to Beijing, and some mixed gauge in and around Hanoi.

Ho Chi Minh City, commonly known as Saigon, is the most populous city in Vietnam, with a population of around 9.3 million in 2023. The city's geography is defined by rivers and canals, of which the eponymously-named Saigon River is the largest. As a municipality, Ho Chi Minh City consists of 16 urban districts, five rural districts, and one municipal city (sub-city). As the largest financial centre in Vietnam, Ho Chi Minh City has the highest gross regional domestic product out of all Vietnam provinces and municipalities, contributing around a quarter of the country's total GDP. Ho Chi Minh City's metropolitan area is ASEAN's 6th largest economy, also the biggest outside an ASEAN country capital.
