The 145 Class 240s built in 1968-70 were CSD's second class of AC electric, following the similar Class 230. They got the nickname 'Laminatka' due to the use of fibreglass in their construction. ZSSK inherited around 100 locos, about half of which are still in use on passengers and freight in the south and west.

ZSSK has no Class 242s but CD's locos are regular visitors to Slovakia. The 242s are technically similar to the Class 240s but differ in having a conventional steel body. In total 86 were built between 1976 and 1981 and the class is currently based at Brno and Plzen depots for working passenger services.

ZSSK Cargo operates 10 Class 756, a modernised Class 753, essentially equivalent to the Czech Class 753.7. ZSSK's 25 Class 757 are similar rebuilds of Class 750s and are fitted with ETH. Both classes were produced by ZOS Zvolen, the 756s in 2008-2010 and the 757s in 2010-2015.

The Class 751 1480hp Bo-Bo diesel-electric was introduced in 1964. Class 752 was the same design but without train heating. ZSSK Cargo operates both classes on freights on non-electrified parts of the Slovak network, although they have lost many of their duties to modernised classes.

The Class 742 1180hp Bo-Bo diesel-electric was developed from the Class 740 to meet CSD's requirements. Almost 500 were built in 1977-86 but ZSSK only got around 90 in 1993. Zvolen rebuilt 17 around 2010 along similar lines to the Class 736 rebuilds. Both classes can be found on shunting and freight duties.

Class 736 was formed by rebuilding unreliable, inefficient Class 735 centre-cab Bo-Bo diesel-electrics with two Caterpillar engines, the main one rated at 1340hp, the auxiliary one at 170hp. There are 24 Class 736.0 in service with ZSSK Cargo and 5 Class 736.1, fitted with ETH and in service with ZSSK.

Class 770, 771, 773

Classes 770 and 771 were CSD's version of the ChME3 Co-Co diesel-electric built in quantity for the USSR. ZSSK got about 90 in 1993 and around 35 are still in service with ZSSK Cargo. Ten locos were modernised at Zvolen in the 1990s, becoming Class 773, now used on the 5' gauge lines in the east.

Class VL11 is a 2, 3 or 4 unit, 5' gauge, 3000V DC electric freight loco built at Tbilisi from 1975 for Soviet Railways, with numerous variations to the design over the years. Ukrainian VL11s work a few km into Slovakia from Uzhhorod to Matovce, where loads are trans-shipped or handed over to Slovakian traction.

Class 730

Class 730 Bo-Bo diesel-electrics were fairly elusive in ZSSK service, being mostly limited to shunting. Only 59 were built in 1978-89 and many went into industrial service. They were intended to replace the ageing Class 720 and 721 but never really caught on. All of ZSSK's locos have been withdrawn or sold.

Class 754

Class 754

Class 754 was the final development of the 'Brejlovic' Bo-Bo design, built new with electric train heating. A total of 86 entered service with CSD and ZSSK received 26 in 1993. They are still active, working many of the remaining loco hauled passenger services on non-electrified lines.

Class 750 consisted of Class 753 Bo-Bo diesels fitted with an ETH generator between 1991 and 1995. A total of 163 were converted, with ZSSK getting 46 after the breakup of Czechoslovakia. They continued to work passenger trains into the 2010s when many were rebuilt again to become Class 757s.

Class 721

Class 721 consisted of 283 end-cab 740hp Bo-Bo diesel electrics built 1962-72 as a more robust version of the Class 720. ZSSK inherited around 100 locos with 86 going to ZSSK Cargo, all of which are now withdrawn. The remaining 21 went to ZSSK and most are still in service, used for shunting.

The Class 150 3000V DC Bo-Bo electric was introduced in 1978 as a DC only version of the Class 350 for express passenger work. The whole class of 27 went to CD at partition, with half being upgraded to Class 151. The remaining Class 150s were regular visitors to eastern Slovakia on trains from Czechia.

Class 125 are twin unit Bo-Bo 3000V DC electric locos based on the Class 123 design but mounted on 5' gauge bogies for use on the SRT between Matovce, on the Ukrainian border, and Kosice steelworks. Each loco has a single cab and they work in pairs. ZSSK Cargo still operate 18 double units.

Class 731

Class 731 Bo-Bo diesel-electrics are low-powered locos intended for shunting and light freight work, built in 1988-1992. They can be considered an improved version of the earlier Class 730 and, like their predecessors, are fairly camera shy. ZSSK inherited 11 examples, all of which are now with ZSSK Cargo.

The Class 140 3000V DC Bo-Bo was the first electric design built in quantity for CSD with 100 produced in 1953-58. The 140 was a mixed traffic loco based on contemporary Swiss practice and survived in Slovakia until the early 2000s. Several locos are still used by independent operators.

The Class 363 25kV AC/3000V DC Bo-Bo was the first of a large group of electric locos. The class went into series production in 1984, designed for mixed-traffic use, particularly on routes that involve both electrical systems. Several have been converted to Class 362 by fitting bogies geared for 140km/h.

The Class 162 is a 3000V DC Bo-Bo electric loco introduced in 1991 and geared for 140km/h running. Otherwise they're the same as the 120km/h Class 163s. ZSSK only has 8 Class 162s, which can be found working fast and local passenger trains on the DC lines in the north of the country.

The Class 362 is the express passenger version of the Class 363 dual system Bo-Bo electric. Only one Class 362 was built new, in 1990, the rest have been created since 1999 by fitting class 363s with 140km/h bogies. ZSSK now has around 24 Class 362s, mainly used on services that cross the AC/DC divide.

Class 183

Class 183 are 3000V DC Co-Co freight electrics, built in 1971 and similar to the earlier Class 182. All 43 went to Slovakia at partition and around half are still in service with ZSSK Cargo. They can be found working freight on the DC lines in the north of the country, often banking trains over the summit at Strba.

Class 163 is the 3000V DC only version of the dual-system Class 363 mixed traffic Bo-Bo, built in 1984-92. Slovakia inherited 37 at partition but 26 were rebuilt as dual voltage Class 361. The remaining Slovak 163s work passenger trains on DC lines in the north, where Czech examples can also be seen.

The 100 Class 131 3000V DC electrics were built in 1980-82, designed to drag heavy freights over the steeply graded Zilina - Kosice main line, where they can still be found. Each loco has a single cab and they invariably run as Bo-Bo+Bo-Bo pairs. The electrical equipment is based on the Class 130, with resistive control.

Skoda built 20 class 350 dual system Bo-Bo electrics between 1974 and 1976. They were CSD's first 160km/h locos, intended for Praha - Bratislava services. All 20 went to Slovakia at partition, where they work between the capital and Kosice, as well as international services to Praha and Budapest.

The Class 753 1780hp Bo-Bo diesel-electric was a development of the Class 751 and fitted with a train heating boiler.. A total of 408 were built in 1968-77. After the end of steam heat they were used on freight until ZSSK Cargo's last locos were withdrawn in the early years of the 21st Century.
Slovakia is a small central European country with an interesting rail system. There are significant differences to Czechia in some areas such as liveries and the rates at which some of the older classes have been withdrawn. One thing that the two countries do share is a very attractive landscape.
