Tanzania–Zambia Railway (TAZARA) (1970–1975)
China financed and built a railway from Zambia's copper belt to the port of Dar es Salaam, giving landlocked Zambia an export route that bypassed Rhodesia and South Africa. Thousands of Chinese and Tanzanian workers laid track across difficult terrain.
The line opened in 1975 and carried freight and passengers between Zambia and Tanzania.
Traffic never reached projections, and maintenance and debt problems persisted for decades.
It shows that external financing can build strategic rail, but traffic volumes decide whether the line pays for itself.
