Besides two-axled tunnel locomotives from 5 to 45 tonnes, Schöma also designs special traction systems for steep gradients of 4 to 7%. The system consists of one locomotive with one or two driven platform cars. The drive system is hydrostatic with the vehicles connected via high-pressure hoses. The vehicles are two-axled or four-axled bogie type with a weight up to 60 tonnes and the platform cars are designed to carry muck, mortar or gravel containers in order to increase the adhesion and traction capacity.
The locomotives have diesel engines up to 500hp and comply with exhaust emission regulations. Schöma says the hydrostatic transmission enables wear-free braking supported by an additional electro-magnetic retarder brake, so that the consumption of brake blocks is reduced to a minimum.
The locomotives are controlled by a microcontroller PLC system developed by Schöma. This comprises synchronised operation of locomotives with two or more units operated by one driver, wheelslide detection and CANBUS communication.
