[5] On November 29, 2023, Pasažieru vilciens launched a rebranding initiative, adopting the new name Vivi (from the Latvian phrase vienā vilcienā, meaning "on one train" and "in one draw (of breath)") and a yellow-grey colour scheme.

[7] The full rebranding process is set to be completed by the end of 2024,[8] although the company's legal name, AS Pasažieru vilciens, will be retained.

[15] Later that year the contract was halted due to irregularities and an appeal from Stadler with the European Commission, an initial financial supporter of the project, and a new procurement organized.

A hire/purchase contract for 25 Stadler FLIRT EMUs was likewise cancelled in July 2014 after an appeal from the other participant, Hyundai Rotem, and another tender organized.

[16][17][18] In December 2015, four contenders – Talgo, CAF, Stadler Polska and Škoda Vagonka – continued participation in the second stage of the train procurement project.

[19][20] Talgo's VitTal was announced as the provisional winner of the €225.3 million contract in November 2018 although Škoda rejected the methodology used to assess price competitiveness.

[28][29] The PMB turned down the final complaint by Talgo on July 4, giving PV the go-ahead to sign a contract with Škoda Vagonka.

[38] While initially it was said that the new trains would enter service in January 2023, cited problems like production delays caused by the Russian invasion of Ukraine and the COVID-19 pandemic, and a long certification process still in progress, have repeatedly pushed this back to 'no earlier' than November.

[46] In May 2020, PV announced that it would procure 8 new diesel trains to replace existing DMUs with Russian-made engines due to the addition of the manufacturers to the United States sanctions list.

[47][48] However, this did not materialise, in part due to uncertainties concerning available funding and with the Ministry of Transport switching its focus on acquiring battery-powered trains (BEMU) by 2026, citing such upsides as a lesser impact on the environment and less noise.

[49] The ministry announced plans to order feasibility study for evaluating the technological and economic aspects of the intended purchase in the second half of 2021.

[50] A tender for 9 BEMU trains (with an option to purchase seven additional ones if funding is available) was announced on 13 April 2022 by the Road Transport Administration, which predicted that new units for a new Bolderāja – Riga – Sigulda line would be delivered by the end of 2026.

[52][53] In September, the outgoing Minister of Transport Jānis Vitenbergs told LTV1 Panorāma news that 'everything has been prepared for the start of a tender and it just needs to be announced'.
