When the North Korean agent was travelling to Brandenburg Gate, she appeared to have boarded the S-Bahn at Friedrichstraße on the elevated platforms. However, the S-Bahn travelling directly from Friedrichstraße to Brandenburg Gate is actually underground. The carriage that she and the agents travelled from Friedrichstraße to Brandenburg Gate is an U-Bahn as depicted by the kaleidoscopic pattern on the vinyl seat covers. S-Bahn Berlin uses the green cloth seat covers. The line graph showing the stations is for S1 line that stops in Friedrichstraße and Brandenburg Gate rather than the U-Bahn as depicted in the film.
