Vossloh G1700 BB

The design is based on the MaK G1206, the first locomotive was built with a 1.5 MW MTU 12V4000 engine, a later version first presented at the 2002 InnoTrans was longer, with a raised engine centre section with a 45° edge chamfer to accommodate a larger 1.7 MW CAT 3512B engine. The lower powered 1.5MW MTU engined version did not remain in production; later orders for this power range being fulfilled by the already numerous G1206. The design resulted in an order from the Swiss Federal Railways for 59 G1700 type locomotives with a CAT 3512B engine rated to 1.5 MW. The Swiss design specified very low emissions, and to comply with this requirement versions of the G1700 built for Switzerland have a diesel particulate filter built in. ==Operators==

1.5 MW MTU engined G1700 (2005) Six of the MTU engined versions were built between 2001 and 2003, the transmissions were Voith L5r4zU2 as used on most of the G1206 locomotives. eventually working long term for Albtal-Verkehrs-Gesellschaft mbH (AVG) as No.468. 1.7 MW CAT engined G1700 (2007) From 2002 onwards CAT 3512B-HD engined G1700s of 1.7 MW rated power with a two speed Voith L620reU2 hydraulic transmission were sold to various private European railway operators. Twenty one have been sold to leasing companies and operators in Germany including five to Häfen und Güterverkehr Köln AG, five to Mittelweserbahn, one each to Berliner Hafen- und Lagerhausgesellschaft mbH, Graz-Köflacher Eisenbahn GmbH, and Wiebe Logistik GmbH, as well as five to leasing company Angel Trains Cargo (now Alpha Trains) for rental to various German operators including Niederrheinische Verkehrsbetriebe Aktiengesellschaft (NIAG), Siegener Kreisbahn GmbH. (now called Kreisbahn Siegen-Wittgenstein), Mittelweserbahn, Neusser Eisenbahn, Rurtalbahn GmbH., Albtal-Verkehrs-Gesellschaft, BASF, Häfen und Güterverkehr Köln AG (HGK) and Verkehrsbetriebe Peine-Salzgitter GmbH. Leasing company Mitsui Rail Capital also acquired three units. 1.5 MW CAT engined G1700 SBB-CFF-FFS Am843 (2010) (2008) An order with the Swiss Federal Railways for 59 diesel locomotives to replace the Bm 6/6 and Em 6/6 types for heavy shunting in freight yards, and trip and construction work resulted in the SBB Am843. The locomotives use a Caterpillar Inc. 3512B DI-TA SCAC engine rated at and Voith L5R4zseU2 two speed hydraulic transmission giving a top speed in the lower gear. The locomotives also have a particulate filter engineered by Hug Engineering of Switzerland which reduces NOx and particulate emissions to low levels. Initially the order of 59 locomotives was for 40 for SBB Cargo, 14 for infrastructure and 4 for passenger services, Other Swiss Am843 operators Sersa Group ordered 3 Am843 type locomotives for work on the Lötschberg Base Tunnel construction. Barbara and Cinderalla. In 2006 for operations on the same tunnel BLS AG received 3 Am843 types; these were fitted with ETCS level 2 safety systems. ==Miniature models==

The G1700 and Am843 has been reproduced as a model railway model by Mehano and Piko in HO scale. ==Notes==
