TheČD Class 700 (FormerlyČSD Class T 211.0) is a two-axlediesel–mechanical locomotive. It was designed forshunting in depots,stations andsidings.

In depots, these small locomotives were used for moving and hauling locomotives during repairs (when the locomotives could not move under their own power) and in places where it was necessary to move electric locomotives without overhead lines (inroundhouses, onturntables and inengine sheds where space were limited and therefore the small overall length over the bumpers often played an important role).

The locomotives were manufactured byČKD between 1957 and 1962. A total of 824 were produced for theCzechoslovak State Railways, various Czechoslovak industrial enterprises and for export to the Soviet Union, theGDR, China, Romania, Albania and Bulgaria.[1]

Technical details

[edit]

Engine

[edit]

They were fitted with a Tatra 111 A engine.[1] The engine is an air cooled, V12, fuel injected, four-stroke diesel. It has an output of 121 kW and a displacement of 14.823 litres. The cylinder bore is 110 mm and the piston stroke is 130 mm. Each cylinder has one intake and one exhaust valve, an injection nozzle and a piston equipped with five piston rings. The engine has three camshafts. One drives the intake valves and the other two drives the exhaust valves. The idle speed is set to 720 rpm, the nominal (maximum) speed to 1600 rpm.

Transmission

[edit]

The locomotives were fitted with a ČKD M 150-4 mechanical, four-speedtransmission which is used to transfer power from the engine to the two drivenwheelsets.[1]
