NürnbergHauptbahnhof/ Hbf is a huge railway station, and like many large train stations, they may initially be confusing for first time users.
The gleis/platform where the train arrives/departs is located on the upper level, and the station building is also multi-level. However, the upper level (gallery) of the station cannot enter the train.
The train passage is located on the street at the bottom of the station building. There are three channels below the track that provide access to the platform. The three passages are named (i) Eastern Tunnel, (ii) Mittel Tunnel and (iii) West Tunnel, but these names are not used for station signs. If you have luggage, etc., only the West Tunnel has lifts, and the trains entering and leaving the other passages are through the stairs. Arriving by train: When arriving by train, you do not have to use the stairs, but the elevator is located at the far end of the platform/canyon - in the F zone. The lift takes you to the west side channel, at the end you can turn to the right to enter the central part of the station, where the main exit is located. Once you are in the atrium of the station, you will find the lower level of the station building with the left baggage facility and U-Bahn access. There are two sets of escalators that can reach this lower level. The second group of esclators, the passage to the city centre (marked 'zugang') before the main street exit - use this passage to avoid having to cross the maze outside the station. From this channel you can reach the Nurnberg ZOB bus stop, which is the departure point for the IC bus to Praha / Prag (and other). Departure by train: When leaving by train, the central hall of the station leads to the middle passage, which is located under the main departure screen, but if you have luggage and want to use the lift, please do not take this road. The West Tunnel with the lift is located on the right side, at the other end of the Burger King in the main atrium, which runs through the length of the station building - next to the platform/canyon.
