Cologne–Frankfurt high-speed line in 2002, the existing Intercity services from the Ruhr to Nuremberg or Munich were mostly replaced by two hourly ICE services. Since their delivery, ICE 3 sets capable of 300 km/h operations are used. After the integration of the Nuremberg–Munich high-speed railway in the nationwide long-distance network in December 2006, this route was received an hourly service and more coupled trains operated to various locations. At the timetable change in December 2007, the Intercity/EuroCity service from Dortmund to Vienna was converted to ICE T tilting trains, so now Würzburg is served by four of the five Deutsche Bahn ICE train classes. Since December 2006, services to Würzburg Hauptbahnhof have been generally scheduled to run through the station at 30 minutes past the hour, to maximise connectivity between long-distance and regional services. Since the beginning of the 2007 timetable ICE line 41 has served Würzburg station hourly. Regional transport routes Würzburg Hauptbahnhof is connected by the following services to the rail network (as of the 2018 timetable): A dense network of services on the lines around Würzburg are operated by DB Regio Unterfranken and another DB subsidiary, Westfrankenbahn. Würzburg is directly connected by five Regional-Express services to major cities such as Nuremberg, Stuttgart, Frankfurt and Erfurt and by five Regionalbahn services to the intervening communities in the catchment area. Deutsche Bahn operates on most routes using locomotive-hauled trains hauling former Silberling carriages. The locomotives are usually members of class 111, 112, 143 and, since mid-2006, the new class 146.2. Trains to Nuremberg and Bamberg are operated with double-deck carriages hauled by class 146.2 locomotives. All Regional-Express services (except the Mainfranken-Thüringen-Express) and the Regionalbahn services to Treuchtlingen reach Würzburg station just before the half-hour and leave it a few minutes after the half-hour. Thus there are connections between them and with two regular long-distance services. Connections with trams and buses Würzburg station is also a central transfer station for trams and buses. In the station forecourt are the Würzburg tram stops of Hauptbahnhof West and Hauptbahnhof Ost (east). This division of departure platforms for trams to the inner city (west) and Grombühl (east) was established in 1996 as a "temporary" measure during the construction of a new station, which has not yet commenced. Immediately west of the station forecourt is the bus station where the majority of urban and regional bus routes start. Future development In 2004, the city
