Duceta (EVN). From today, a wonderful new trainset will connect Esto's coasts: the Trans Estontestan Express, or for short: TEE. With its diesel engines, the train reaches 160 km/h. The modern outward appearance is of appealing beauty. Some photos from the test runs here: https://vexillium.fandom.com/wiki/Estontetsan_Technology#TEE_-_Trans_Estontetsan_Express. 
[tech: On the indicated page you find an extra link to the real TEE (Trans Europ Express), an international first-class railway service in western and central Europe 1957-1995. At the height of its operations the TEE network comprised 45 trains connecting 130 cities.]
Some extra trainsets are built as mobile headquarters or rolling palaces. Their exterior is not yet publicised but may be just the same, for better concealment.
