The inaugural journey commenced on 29 October 2012. The public affectionately refer to it as Treni ya Mwakyembe in honour of Harrison Mwakyembe, the Transport Minister at the time. The Citizen reported in January 2013 that 'Zambia was opposed' to the project utilising the TAZARA track and that it wasn't 'properly consulted'. Zambian officials insisted that the matter ought to have been brought before the board of directors for approval as both the governments are equal shareholders. Minister Mwakyembe refuted these allegations saying all procedures were adhered to. An anonymous TAZARA board member commented that they had failed to convene their quarterly meeting for the past six months. The Chartered Institute of Logistics and Transport presented an award to Mwakyembe in December 2013 for introducing this service. The TRL Line launched on 1 August 2016, plying the airport route 3 times in the morning from 6 am and 3 times in the evening from 15.55 hours.
