The Integral is a diesel multiple unit (DMU) train type operated by Regiobahn GmbH on commuter services in North Rhine-Westphalia. Between 1998 and 2020, they were operated by the Bayerische Oberlandbahn on regional services between Munich, Bayrischzell, Lenggries and Tegernsee. They were built by the now defunct Jenbacher Werke.[1]

Each Integral unit consists of five sections, formed as shown in table below.[2] The two "FGZ" sections are suspended between the end- and intermediate cars.[2]

Technical specifications
The trains are powered by diesel-hydraulic motors.[2] One end car has all wheelsets powered, the other end car has only one powered wheelset. All six wheelsets use active radial steering.[2] The trains are able to run in multiple unit formation.[3]
History
The trains entered service in November 1998.[3] Following problems and malfunctions, the fleet was returned to its manufacturer in Jenbach, and was overhauled, which increased their reliability.[4]
One unit was used at the Test- and Validationcenter Wegberg-Wildenrath for testing of an anti-collision system by the Deutsches Zentrum für Luft- und Raumfahrt (DLR).[5]
The Integral trains were withdrawn by Bayerische Oberlandbahn after their last day of service on July 25, 2020, being replaced by LINT 54 units.[6]
After their withdrawal from service in Bavaria, Integral trains were transferred to the Regiobahn GmbH in North Rhine-Westphalia, where they entered service on VRR S-Bahn line S28 in December 2020.[7]
