Vossloh's type designation for the locomotive class is Vossloh G800 BB. A further 6 locomotives have been built and have been part of Vossloh locomotives leasing fleet.

ÖBB 2070

The ÖBB 2070 was ordered in November 1998 as the result of a competitive tender.[3] Along with the ÖBB Class 2068 built by Jenbacher in the 1990s they were intended to replace old shunting machines on the railway. The acquisition of the locomotives was part of a plan to modernise the Austrian locomotive fleet, which included the purchase of the ÖBB 1016 "Taurus" and ÖBB 2016 "Hercules" locomotives in the first decade of the 21st century.[4]

The locomotives are built to the standard MaK B'B' diesel hydraulic off-centre cab design as typified by the MaK G1206. ÖBB's locomotives have air conditioned cabs and can be operated in multiple. Remote control operation as well as automatic shunting couplings are also a standard feature of the ÖBB locomotives.[2]

Industrial use

6 locomotives were produced and leased by Vossloh to other companies; primarily industrial clients including BASF, BP, Chemion Logistik GmbH (formerly part of Bayer), Ruhr Oel and Thyssen Krupp,[5][6][7][8][9][10] two of the locomotives were eventually sold to Lenzing AG in 2005 and 2008.[9][10]

Miniature models

Versions of the locomotives have been produced by Jagerndorfer, Liliput and Märklin/Trix in HO scale, and by Minitrix in N scale.[11][12]
