Ömazislav/Gorganstien Delticron (Bus)

The Ömazislav Delticron, later referred to as the Gorganstien Delticron, is a line of intercity and commuter motorcoaches and transit buses that come in nominal lengths of 35' rigid, 40' rigid, and 60' articulated. They were first produced by Ömazislav Otobüs from 1967 to 1979, and then from 1981 to 2002 by the Czechoslovak Gorganstien Otobüs division of Gorganstien trucks. The buses are sold with a range of powertrain technologies in addition to the numerous lengths that are available, including conventional diesel, compressed natural gas (CNG), diesel-electric hybrid, hydrogen fuel cell, overhead electric wire, and battery electric.

Derived from the GM "old-look" transit bus, the original Delticron was specifically based on the TDH-5108 body style. The Delticron is unique from the GM "old-look" in the fact that it had a flatter windshield and an optional middle door delete. Most Delticron buses were powered with a Tatra diesel or a Mercedes diesel engine, however it is also powered by a Detroit Diesel 6-71 inline six-cylinder diesel engine and the shorter models were powered by the Detroit Diesel 4-71, a four-cylinder version of the same diesel engine.

While produced largely for transit use, the Delticron is also based on the Saribus series, which consisted of licensed copies of GM's model TDM-3207, TDH-3610, and to a lesser extent, the TDH-5108. The Delticron also departs significantly from the "old-look" in that despite its 40 feet length, it is available in capacities up to 81 passengers as opposed to 51 passengers. A few examples of the original Delticron were also produced with a Napier Deltic engine, however these were rather prototypes and only three examples were produced for the Soviet Union. It is also the only bus in the world at the time with the option of a Napier Deltic as a powerplant.
