The storage hybrid locomotive HDB 800 from Toshiba Railway Europe is a hybrid locomotive , for which the prototype was produced for the drive under catenary as well as with diesel engine and battery drive . The series locomotives, which have now been firmly ordered, are now only equipped with diesel-electric drives and battery drives . It is technically based on the HD 300 series from the same manufacturer and is intended to represent the next generation of heavy shunting locomotives at DB Cargo . The first prototype locomotive was completed in 2019, 50 locomotives have been ordered from DB Cargo, and a further 50 locomotives have been ordered from logistics partner Railpool . The power of the locomotive is laid out above that of the Alstom H3 .

history

Shunting locomotive of the Schalke ironworks , the frame and the driver's cab for the HDB 800 were taken from this construction

DB Cargo's shunting locomotives reached the age of 40 at the end of the 2010s and have to be replaced. Your drive at the time no longer meets today's requirements for environmental compatibility and energy efficiency . In order to replace the class 290 locomotives and their modification variants , a completely newly developed drive configuration is to be introduced. At the same time, two class 294 locomotives were converted into a hybrid locomotive with a diesel engine and battery drive and presented at the Transport logistic trade fair in Munich . At the ÖBB , the hybrid drive is relied on in shunting on track systems that are free of overhead lines in places.

The prototype locomotive with the NVR number 90 80 1018 001-0 and the planned series designation 280.5 was completed at Maschinenbau Kiel and also exhibited at Transport logistic in June 2019. Talks were held about the future use of the locomotive with potential customers from the Netherlands and Eastern Europe. In addition to the hybrid technology, the locomotive has an appearance similar to the ÖBB 1063 . The production of the first 10 pre-series locomotives began in mid-2019; the production location could not yet be found in the literature. Series production will then take place under the responsibility of Toshiba in the DB Cargo plant in Rostock Seaport . The extensive tests and approval procedures, which should be completed in early 2021, should then begin in mid-2020. The pre-production locomotives are also part of the test. In the meantime, 50 locomotives for DB Cargo and 50 locomotives for Railpool have been firmly ordered; they are to be designed as hybrid locomotives for diesel-electric drive and battery drive.

commitment

With their drive configuration, the locomotives can take on the tasks of heavy shunting and heavy line service under catenary . The diesel engine power is sufficient for transfer power in the range of the V 90 series. The battery drive is intended for operating situations where a diesel engine is unprofitable or can be used as a booster when starting or climbing in catenary-free operation.

technology

The locomotive is equipped with a central driver's cab and has two stems of different lengths. In the prototype, the power supply under catenary was implemented by a single-arm pantograph installed on the roof of the driver's cab . The series locomotives are not manufactured with overhead line operation. The batteries and the fuel tank are located between the bogies under the driver's cab . Two diesel generator units with their fans are located in the front of the locomotive. The locomotive's braking equipment is located in one, the electrical equipment in the other front end. The locomotives from the series locomotives will have a different appearance compared to the machine shown at Transport logistic. For reasons of time, the frame of a locomotive from the Schalke Ironworks was used for the prototype locomotive . The series locomotives will then receive a universal frame developed by Toshiba.

Also from Toshiba are the bogies with the spring-loaded drive motors, which are a novelty compared to the previous three-phase asynchronous machines . The motors are synchronous motors with a permanently magnetized design. The current is transmitted in the same way as with conventional three-phase asynchronous motors. What is new is that instead of the rotor sheets and windings, permanent magnets are glued to the rotor. This technology has proven itself several times in Japan for rail vehicles and is being used here for the first time in Europe. Compared to the three-phase asynchronous machine, this design achieves efficiencies of up to 96%.

The locomotive can be powered either by the diesel engine or the battery under catenary-free sections. Two MAN diesel engines are available, which deliver a total of 940 kW. The battery is a lithium titanate battery , it has an energy content of 240 kWh and is intended for a service life of over 10 years. The locomotive is equipped with a device for autonomous driving , the maximum speed is set at 6 km / h.
