ZOS Zvolen is to modernise a further 15 Class 810 single-car railbuses for Slovakian operator Zeleznica Spolcnost, following on from 10 vehicles completed in 2001-02.
To be rebuilt as Class 812, the modernised vehicles (above)will feature 257 kW MAN D2866LUH21 engines with Voith Diwa 863-3 hydraulic transmission, automatic gear changing control by Mirel 812 electronics, and a top speed of 88 km/h. Eberspächer-Hydronic heaters will be installed, along with replacement seats (right)and a self-contained toilet module.
The refurbished units will replace Class 830, 850 and 851 railcars dating from the 1950s on lines in central Slovakia. Another 30 railcars will be upgraded by late 2005, at a cost of SK380m. ZSSK’s rolling stock investment plans for this year are being funded using SK1·32bn from internal funds and SK2bn from external sources. Eurofima is providing a €10m credit.
Six Class 735 Bo-Bo diesels locos are currently being rebuilt into Class 736. Used on light passenger and freight services, upgraded locos will have an 990 kW Caterpillar 3512 engine, Lokel Intelo Maxi microprocessor controls, Siemens traction alternator and 1200 kW electric brakes.
The first of six light DMUs built by a consortium of Stadler Bussnang AG, ZOS Vrutky and Bombardier Switzerland has been rolled out. Based on Stadler’s GTW 2/6 design, the Class 840 has a 550 kW MTU engine and AC transmission, giving a top speed of 120 km/h. The two-car units will replace loco-hauled trains operating on mountainous routes around Zvolen.
A further 28 inter-city and 18 other coaches are to be upgraded by ZOS Vrutky, which has completed overhauling first and second class air-conditoned rolling stock for use from December 14 on through trains between Kosice and Wien.
