completed in June 2011. This construction work included the renovation of the royal pavilion. Since the summer of 2011, Deutsche Bahn has been developing a future retail space under the tracks of the north and south hall of the station. Around €25 million were expected to be invested by 2014. It has around 40 storefronts with a total area of 14,000 square metres. The first new stores opened in August 2013, although construction work had not been completed in April 2014. The second stage of the development of the Dresden railway node was planned in 2009 to be completed in 2011. However, this construction phase was not included in the 2011–2015 federal Investment Framework Plan (Investitionsrahmenplan) and construction is not currently scheduled (as of 2012). In September 2013, Deutsche Bahn said that the platforms of the central hall would be replaced by 2019 and they would also be slightly raised. The Förderverein Dresdner Hauptbahnhof e. V. (Friends of Dresden Hauptbahnhof) supported the renovation and enabled the recovery of some details about the required conservation measures. So broken decorative elements on a sandstone facade of the clock tower were returned to their correct places, windows were equipped with arches and architraves and the crowning group statue of Saxonia with personifications of science and technology have been restored. Building The station building is oriented in a northwest–southeast direction and is divided along its longitudinal axis into three train sheds with eye-catching arched roofs. The lobby is located to the east of the central and largest of the three buildings and it is centered between the outer halls; it has an approximately square plan. A small forecourt facing on to federal highway (Bundesstraße) 170 is in front of the main entrance. This road passes at roughly right angles under the railways running through the other two halls. The tripartite platform hall covers an area that is 60 metres wide and 186 metres long. The iron arch structure of the roof rises up to 32 metres high and has a width of 59 metres. The spans of the train sheds are 31 or 32 metres and 19 metres wide. The dimensions of the roof were necessary during the days of steam so that smoke could be blown away. On the other side of federal highway 170 opposite the main entrance is the station's east wing. Several bay platforms are arranged in an elevated position
