VEHICLES OF LIGHT SHUNTING SERVICE
THE DIESELECTRIC LOCOMOTIVE 711
The dieselelectric locomotive 711 is result of reconstruction of the locomotive T334.1 with dieselhydraulic power transmission, which was produced in ČKD Prague and TSM Martin, Slovakia. As a result of reconstruction the power transmission was changed into dieselectric and it also caused another important change- modernization of driving aggregate. The locomotive was changed into more efficient vehicle with respect to the environment- which was caused by lower comsumption of fuel. Reconnstructed 3- axle locomotive 711 with dieselelectric power transmission is suitable for track service of industrial companies and also for light shunting service, for example for railway depos.
Dieselelektrický rušeň radu 711 vznikol rekonštrukciou lokomotívy T 334.1 s dieselhydraulickým prenosom výkonu, ktorá bola vyrábaná v ČKD Praha a TSM Martin. Rekonštrukcia lokomotívy zmenila prenos výkonu tejto lokomotívy na dieselektrický a modernizovala hnací agregát. Lokomotíva sa dak dostala na kvalitatívne novú úroveň – pôvodne dieselhydralulický prenos výkonu s nižšou celkovou účinnosťou bol nahradený s prenosom s vyššou účinnosťou. Lokomotíva dosahuje po rekonštrukcii značné úspory pohonných hmôt. Rekonštruovaná 3-nápravová lokomotíva radu 711 s dieselelektrickým prenosom výkonu je určená pre posun na vleškách priemyselných firiem (huty, železiarne a pod) a pre posunovaciu a ľahkú traťovú službu ako aj na posun v koľajových obvodoch lokomotívnych a vozňových diep ŽSR.

THE DIESELELECTRIC LOCOMOTIVE 712
The dieselelectric locomotive 712 is the result of complex reconstruction of original T334. The reconstruction of the locomotive has changed the power transmission to diesel electric and has modernized the driving aggregate. The original diesel-hydraulic power transmission with lower total efficiency had been replaced by transfer with higher efficiency. The locomotive achieves substantial savings of fuel after the reconstruction. The reconstructed 3-axle locomotive of 712 series with diesel electric power transmission is designed for shunting on industrial works sidings and for shunting and light track service. The whole upper part of the locomotive is newly made. The whole driving aggregate

THE DIESELELECTRIC LOCOMOTIVE 724
The dieselelectric locomotive 724 has been introduced as the result of the reconstruction of 740(T 448.0). The reconstruction resulted in operational and maintenance savings as well as improved ecological parameters and locomotive operating life. The locomotive is designed for semi-heavy shunting and/or freight transport with the range of exploitation on national, regional lines as well as sidings. The environmental conditions are limited by height of 1000 m above the sea level, temperatures from minus 30˚C up to plus 40˚C, maximum relative humidity of 90% at the temperature of 20˚C. New aggregate, hoods and cabins have been fitted into the modified main frame of the original locomotive. There are two diagonally placed operating boards in the cabin equipped with the control of movement and electrodynamic brake indicators. To improve conditions in the summer months the cabin is equipped with two ventilators placed above the operator’s place and “Tropiko” double roof. There are two sprung adjustable chairs in the cabin. The floor is covered by antiskid material. Front windows are equipped with adjustable sun protection blinds. The operating board surfaces as well as the roofs of the hoods have been made from material of dim surface. There are two original double-axle bogies on the locomotive. Each axle is a driving one and is powered by TE 005C (TE015) traction engines. The driving aggregate is composed of CATERPILLAR 3412 E DI-TA combustion engine linked with SIEMENS DRASOV traction synchronous alternator. The engine cooling system is fluid-type with closed circle and bypass.
