DBAG Class 152

The Siemens ES64F is a high-performance locomotive from Siemens ES64 Euro Sprinter - type family for the heavy freight traffic, which can also be used for passenger trains. The locomotives are used however, almost all freight trains - both by the Deutsche Bahn AG (DB ), in which it is designated as the class 152 as run by the private railway ITL, in which two of these locomotives.

History

DB required from the turn of the millennium appropriate replacement for amounts earmarked for decommissioning locomotives of the series 150. Following the tender in 1993, the DB Krauss-Maffei received as a general contractor awarded the contract for the construction of locomotives. Siemens Transportation Systems supplied the electrical equipment.

In September 1995, finally began production. The first locomotive of the series, 152 001, was then passed on 10 December 1996 in a ceremony staged roll-out in Munich- Allach to the DB and then subjected to an extensive testing program. In the second half of 1997, three ( Source: Siemens AG) were further locomotives delivered brought forward, which completed further testing. On 31 July 1997, the type approval was granted by the Federal Railway Authority so that from March 1998 the serial production. The machines were taken at the manufacturing plant in Munich and Uerdingen. The timetable change in May 1998, the first twelve locomotives went into the operating plan.

Until 2001 170 were delivered from originally planned 195 machines to the DB. It was planned to use the locomotives in Austria. However, the Austrian authorities refused admission because they evaluated the track forces to be too high. In order to still have modern machines for the Austria - transport available, the DB changed the order of the last 25 locomotives in an order of Zweisystemloks the 182 series (identical to ÖBB 1116) to which is approved in Austria.

An option on an additional 100 machine was August 1999 converted into an order of multi-system locomotives of the series 189.

Two locomotives were delivered in 2000 to the leasing company Dispolok, which was at that time owned by Siemens. The locomotives were sold to the company ITL 2005. At the locomotives names ES64F -901 / 152 901 or 902 are mounted, the UIC number is, however, 91 80 6152 196-2 D -ITL or 197-0.

Construction

The series is based on the constructed prototype of Siemens ES64P. However, since it was clear that the machines should be used exclusively for freight traffic and a top speed of 140 km / h was considered sufficient, could do without the use of fully cushioned traction motors and much easier to and cheaper Tatzlager drive be used. This applies through the use of modern induction motors at low speeds as relatively resistant to wear.

Otherwise, a modern machine with three-phase asynchronous traction motors and dual vented disc brakes arose. A partially redundant execution of highly stressed parts in the drivetrain contributes significantly to the high reliability and availability of the series.

The main transformer is located under the floor between the bogies. Each bogie has a self-contained electrical equipment, consisting of three input rectifiers in regenerative four-quadrant design, the DC voltage intermediate circuit and two inverters (one per engine ). This ensures that in the event of a component of the drive train does not fail the entire bogie, but merely reduces the available traction. As a water-cooled power semiconductor GTO thyristors are used. The braking force of the electric regenerative braking is 150 kN in the range between 10 km / h and 140 km / h

The locomotives are equipped with a train line for the power supply of passenger trains as well as shuttle train and emergency brake, so that they can be used in heavy passenger service. Was it by splitting the DB AG and assignment of locomotives for freight division of DB, have not been used since the late 1990s.

The engine room is crossed by a connecting both cabs aisle. On both sides the electrical equipment, compressed air and brake equipment and the extensive cooling devices are arranged on the outer walls of the locomotive body. All units are designed in the form of separate, interchangeable modules that are inserted from above into the vehicle. Attention was paid to the shortest possible connections, and in particular for the main power lines. The control cables and piping are installed in channels under the center aisle. The control and monitoring equipment are concentrated at the two ends of the engine room.

The cab room is air-conditioned, heat and sound insulated and has a fairly generous amount of space. Amenities for the driver are also an air suspension seat and a thermal compartment. The locomotive has the so-called unit leader level.

A special position within this series takes a 152 190, which grew out of the 152 032 and was tentatively equipped with IGBT power semiconductors.

Use

The supplied to the DB locomotives the DB Schenker business unit allotted and fully stationed in Nuremberg Rbf. The locomotives are used nationwide in freight service.
