2020 year has been a turning point for the entire humanity. The COVID-19 pandemic has not only revolutionized our way of thinking, but it has changed the way we live, leading to having limitations on any aspect of our daily life, from the smallest things to the biggest. This extraordinary situation has afflicted the railway world, too, since the movements have been limited drastically and new rules have been introduced. This thesis focuses on analyzing passenger transport's current situation on high-speed trains in this particular historical period we are experiencing, the COVID-19 Era. It aims to create hypothetical scenarios of passengers' distribution inside a train wagon with current health and hygiene rules.
