Diesel locomotive type 6Da
The 6Da is a 4-axial, 2-bogie locomotive with an electrical transmission. This unit meets UIC 505-1, issue VI, requirements referring to a gauge and crookedness of a railway track determined in the report ORE B55 Rp.8.
The locomotive is applied for operation in a moderate climate with ambient temperature from -25oC ÷ +35oC, and altitude 1000m, at an average humidity 70% above sea level.
The locomotive is specially suitable for mean and heavy switching at stations and hump-yards. A suitable design of the electrical systems allows to gain max. speed up to 90 km /h. This locomotive can be used for hauling both passenger coaches and light freight cars.
The electrical system is adjusted for ( during line duty ) coupling two locomotives of the same type. It allows to obtain a double tractive force.
