DB Class VT 11.5

The VT 11.5 was based on the prewar DRG Class SVT 137 and the innovative designs by Franz Kruckenberg as well as on the experiences with the postwar DB Class VT 10.5. Mostly the trainsets consisted of two motor units built by MAN AG, one dining and kitchen car, one dining and bar car built by Wegmann & Co., and three coaches assembled by Linke-Hofmann-Busch. The weight of a seven-unit trainset was , the length was . Motor units and coaches were coupled by automatic Scharfenberg couplers, thus allowing trainsets up to ten units and coupling of two trainsets. From 1963 a second series of these trains were sold to the Danish State Railways (DSB) for use as national express trains (lyntog, meaning 'lightning trains'). This was a modified version which could be separated into two independent units and loaded onto the Great Belt ferries, and a total of whole or 11 half units were sold. It was given the designation "litra MA", ranging from MA 460 to 470. In 1984 the trains were painted in a silvery color, which resulted in the nickname "Sølvpilen" (Silver arrow). Another affectionate nickname was "Flyvende Støvle" (Flying Boot) or "Staniolekspressen" (the Tinfoil express). In 1990 these trains were phased out from Danish service and donated to a Polish railway (first private in Poland - Lubuska Kolej Regionalna Spółka z o.o.). After collapse of that private railway (1994), all these trains were scrapped. One half unit (The MA 460) was not donated to the Polish railway, but given to the Danish Railway Museum, where it still remains operating as a museum train. ==Operational==

Trans Europ Express The first trains were commissioned in 1957 and used on the following international TEE routes: • TEE 31/32 Rhein-Main Frankfurt/Main – Amsterdam2 December 1957 – 27 May 1967 • TEE 74/75 Saphir Dortmund – Oostende15 July 1957 – 26 September 1971 • TEE 77/78 Helvetia Hamburg Altona – Zürich14 October 1957 – 1 March 1965. • TEE 168/185 Paris-Ruhr Dortmund – Paris Nord23 December 1957 – 29 May 1960 & 30 May 1965 – 31 May 1969 In the 1960s, due to ongoing electrification, routes like the TEE Helvetia were changed to electric locomotive-hauled train sets. The diesel trainsets were reallocated to other TEE routes: • TEE 155/190 Parsifal Hamburg Altona – Paris Nord29 May 1960 – 29 September 1968 • TEE 25/26 Diamant Dortmund – Antwerpen30 May 1965 – 29 September 1971 • TEE 84/85 Mediolanum München – Milan1 June 1969 – 28 September 1972 Intercity In 1971, DB started their new first-class-only InterCity system, using mainly the 601 series on the non-electrified InterCity routes. The regular maximum speed was set to 160 km/h for seven-unit trains. For trains up to 10 units the 602 was used. In 1979, the InterCity system was expanded and second-class compartments were introduced for these trains, meaning the end of 601/602 use for these trains. Tourism From 1980, the 601/901 was used for special tourist services. Deutsche Reichsbahn The fall of the Berlin Wall in 1989 led to a new life for the 601 as an InterCity train. One of the 10-unit trains was loaned from Italy to the East German Reichsbahn (DR) and served from July 27, 1990, to September 29, 1990, as InterCity Max Liebermann on the route Hamburg–Berlin. One part of this train had been later repainted blue-beige and is still to be seen at the Augsburg Railway Park museum. It today houses a restaurant run by celebrity chef Alfons Schuhbeck. == Technical details ==

Class 601 The VT 11.5, later 601 had two motor units at the head and the tail of the train. Each one had an 809 kW diesel from MTU and a hydraulic transmission from Voith or Maybach. The maximum speed was , later . All coaches were air-conditioned. Class 602 , in Nuremberg. In order to run ten-unit trains with a maximum speed of 160 km/h, four VT 11.5 were rebuilt in 1970 and received AVCO Lycoming TF55 gas turbines supplied under license by Klöckner-Humboldt-Deutz in place of their original Diesel engines. ==Preservation==

One trainset has been preserved in operating condition by DB, consisting of power cars VT 11.5 5014/19 and eight unpowered cars, and it operates occasionally on special excursions, including for private hire. The only other car preserved from this series is VT 11.5 5012 (as 602 003, its later number), preserved at the Nuremberg Transport Museum. ==See also==
