The Dar es Salaam commuter rail, informally known as Treni ya Mwakyembe, is an urban and suburban commuter rail network serving the Tanzanian commercial city of Dar es Salaam. It is one of the two initiatives taken by the government to ease travel within the congested city; the other being the Dar es Salaam bus rapid transit system. Services are provided by the Tanzania-Zambia Railway Authority (TAZARA) and the Tanzania Railways Corporation (TRC).
