Class 730 Bo-Bo diesel-electrics were fairly elusive in CD 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. Most of CD's locos have been withdrawn or sold.

The 110 Class 230 25kV AC Bo-Bos were CSD's first production AC electrics, built in 1966-67. Next came 145 similar Class 240s in 1968-70. The 230s and 240s were unusual for the extensive use of fibreglass in their construction, hence their nickname 'Laminatka'. CD's locos are now confined to freight traffic.
Class 263

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 from Class 162s.

The Class 372 Bo-Bo electric is a dual system Bo-Bo, similar to the Class 363 but for working from 3000V DC or 15kV AC on trains to Germany via Bad Schandau. A total of 16 were built for CSD between 1988 and 1991. Six locos were later modified for 160km/h running by CD and reclassified as Class 371.
The Czech Republic, a.k.a. Czechia, is a small country full of railway interest, with an attractive landscape, a variety of traction and, at one time, an almost infinite multiplicity of liveries. Sadly, modernisation is now taking its toll, making the railway more efficient and less interesting every year.
