SBB-CFF-FFS Am843

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 1500 kW and Voith L5R4zseU2 two speed hydraulic transmission giving a 40 km/h (24.9 mph) top speed in the lower gear.

 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, as the order was fulfilled the locomotives assigned to passenger train work were re-assigned to SBB Cargo, and. with the increase in cross border traffic, fitted with the Indusi safety system for German operations. 14 more locomotives were ordered in 2005.

Locomotives numbered Am843-001 to Am843-028 are assigned to the infrastructure division (SBB Infra), Am843-041 to Am843-043 were delivered in 2009 and assigned to passenger division SBB Personenverkehr, and Am843-050 to Am843-095 were assigned to SBB Cargo.
