VEHICLES OF MODERATE SHUNTING SERVICE
DIESEL LOCOMOTIVE 736
The diesel locomotive 736 was created by the reconstruction of the original locomotive 735. From this original one there is left only the travel without adjustment that is formed by two-axle (four wheel) bogies. It is designed for traffic on lightweight passenger trains, for medium heavy shunting and freight transport, under the climatic conditions from -30 °C to +40 °C and up to the altitude of 1000 m. To support the traffic on lightweight passenger trains, the locomotive is equipped with the electrical heating generator and supplying the system of the attached carriages. The locomotive has two driving aggregates: the main and auxiliary ones. The Diesel engine has a power of 990 kW. In front of the cabin there is an across-mounted auxiliary aggregate with the power of 124 kW, which is used for running the locomotive itself, or for shunting one up to 2 carriages. The cooling of both Diesel engines is liquid. The locomotive can work at a multi-member regime. The standard equipment includes an electro-dynamic brake.There is the machinist cabin in the tower construction.. The floor covering is made under the anti-slip treatment. The cabin is elastically placed on the frame, it is air-conditioned. There are two cushioned seats adjustable alongside and vertically. The parts of the cabin are also a clothes cabinet, a case for tools, a case for the documents, a wash cabin with hot and cold water, microwawe oven and a fridge. The locomotive 736 has been awarted by Gold Medal at ŽEL RAIL exhibition in Vrútky.

THE DIESELELECTRIC LOCOMOTIVE 746
The dieselelectric locomotive 746 is the result of complex reconstruction of original series of 742 (T 466.2). The reconstruction resulted in significant operating and maintenance savings, as well as it improved the ecological parameters and the operating life of the locomotive. The locomotive is designed for shunting and freight transport on national, regional lines and sidings in Central European climatic conditions up to the altitude of 1000 m above the sea level, at temperature range from – 30°C to + 40°C and maximum relative air humidity of 90% at the temperature of 20°C. From the original locomotive the main frame was taken over, on which the necessary adjustments were made for the fitting of new aggregates, bonnets and cabin. There are two diagonally situated control panels in the cabin equipped with controllers of movement and electrodynamic braking. At the operator’s position there are two sprung seats that are adjustable alongside and vertically mounted on a mechanism enabling movement along the sides of the cabin and adjustable footstools. The Webasto CC8 air-conditioning unit set into the roof of the cabin ensures the microclimate in summer. The cabin is heated by an independent hotwater heating aggregate Webasto Thermo 300 or by waste heat from the internal circuit of the combustion engine. The floor covering is made of antiskid treatment. The one- piece front windows have negative slope and they are fitted with screen washers, electrical screen wipers and electrical blinds. The top of the panel and bonnet roofs was treated by anti-reflex dim surface. The locomotive has two original double-axle chassis. Each axle is a driving one and is driven by TE 005C (TE 015) traction engines. The driving engine aggregate consists of SCAC 3508B combustion engine connected with SIEMENS 1FC2 454-4 traction synchronous alternator. The cooling of the combustion engine is of fluid-pressurized type. The combustion engine is cooled by two independent circuits.
