The concept design of the Rail Baltica rolling stock depot to be built on the border between the city of Tallinn and Rae municipality has been developed and based on this 3D visualization has also been developed.

The largest Rail Baltica rolling stock depot is designed by OÜ Real Project and NORD PROJEKT AS.

The rolling stock depot will primarily repair and maintain trains whose final terminal is Rail Baltica Ülemiste joint terminal, but the depot must be ready to provide maintenance and repair services to the rest of Rail Baltica 1435mm gauge train fleet. The Ülemiste rolling stock depot must enable parking for the passenger fleet and the performance of other necessary maintenance functions.

The depot can accommodate seven trainsets at a time, according to Rail Baltica's operational plan 26 highspeed trains and 16 regional trains will move in the infrastructure.

The depot will be designed in several stages and the start of construction is planned for the first half of 2022.
