speed is 100 km/h and its engine generates 993 kW (1,350 PS). Ten locomotives from the last batch of 150 engines were additionally equipped with stronger brakes and modified drives and were employed on ramps. These locomotives, originally numbered V 100 2332 to 2341 were reclassified in 1968 as DB Class 213. They replaced the steam locomotives of Class 82 and 94 on the Murg Valley Railway and in the Westerwald. In the Murg Valley they were replaced in their turn in 1972 by the DB Class 218. The last Class 212 was withdrawn from normal service in 2004, some have been preserved or found use with private firms. Locomotives of the tunnel rescue train – Class 214/714 Due to the many tunnels on the new railway line from Würzburg to Hanover, special rescue vehicles were needed. The Bundesbahn developed the Tunnel Emergency Train (Tunnelhilfszug or TuHi) as an external rescue system. In May 1988 the first TuHi went into service at Fulda. Diesel engine 212 244-8 was used as Locomotive 1 and 212 257-0 as Locomotive 2. The Würzburg TuHi followed in August 1988 using 212 236-4 as Locomotive 1 and 212 352-9 as Locomotive 2. Number 212 271-1 was held in reserve. All five 212s for TuHi were rebuilt between May and August 1988 at AW Kassel. Both TuHi are one-way trains, i.e. they can only be used in one direction. They consist of transport wagon 1, the equipment wagon, the fire fighting wagon, the centre wagon, the first aid coach and transport wagon 2. Locos 1 and 2 are also different. Loco 1 has a video and infra-red camera, two large and two small headlights and yellow flashing lights. Loco 2 does not have an infra-red camera. With effect from 1 January 1989 the five engines of Class 214 were reclassified, retaining their serial numbers. Official all 5 locos are allocated to Bw Würzburg. Both engines with the Fulda TuHi had "Bw Fulda" incorrectly painted on them. On 29 May 1991 the Federal President, Richard von Weizsäcker, gave the starting signal at Kassel-Wilhelmshöhe to announce that the new Hannover–Würzburg and Mannheim–Stuttgart high-speed railways were now fully in service. That meant four more locations for TuHi were required. In addition to Fulda and Würzburg, TuHi also had to be stationed at Kornwestheim, Mannheim, Kassel and Hildesheim. The TuHi in Fulda had to be organised as a bidirectional train,
