moving from one station to other as well as from aboveground to the underground during the rush hour. Sendlinger Tor station (U1/U2/U7/U8 and U3/U6) — Renovation In Progress Due to poor design and unanticipated explosive growth of passenger traffic, Sendlinger Tor station has severe congestion and chokepoints for passengers moving between upper U3/U6 and lower U1/U2/U7/U8 platforms as well as upper levels (mezzanine and street). The €150 million renovation and upgrade of station was approved on 30 December 2015 by administrative district of Oberbayern. The project is scheduled to be completed in 2022 or 2023. The U3/U6 platform has wide staircases and escalators connecting to the U1/U2/U7/U8 platforms below and mezzanine level above, and they created the narrow passageways on the platform. The narrow passageways lead to the dangerous chokepoints for passengers moving between the platforms or levels, especially during the rush hour. The U1/U2/U7/U8 platforms have only one corridor in the middle, connecting to the U3/U6 platform and upper levels. The combined landings of ascending and descending escalators and wide staircases from U3/U6 platform are placed too close to the U1/U2/U7/U8 platforms at either end of middle corridor. This causes the severe congestion during the rush hour when the passengers going downstairs must push through the passengers who are going upstairs. The five lifts at the station do not connect directly to every level (two platform levels, mezzanine level, and street level). The two street level lifts are connected the mezzanine level only: they are located inconveniently further away from popular shopping street, Sendlinger Straße, requiring the passengers to cross the busy intersection to reach them. From the mezzanine level, the passengers either use two lifts to reach U1/U2/U7/U8 platforms or another lift to reach U3/U6 platform. If the passengers wish to transfer between upper and lower platforms via lifts, they must reach mezzanine level first and travel considerable distance to other lifts. Additionally, the new EU safety directive 2016/798 requires additional fire protection in the subterranean train stations. Thus, installation of the partitions and doors that close automatically during the fire alarm at the landings of staircases and escalators. The U1/U2/U7/U8 platforms have the new dedicated corridors built at north and south ends. The north corridor (Sonnenstraße-Verbindungstunnel) is connected to the mezzanine level: one set of escalators connecting to the mezzanine area and one staircase connecting to the lower landings of entrances A and B. The south corridor
