E-u N 684-37: the steam locomotive of innovator.<br>
E-u ("povered E") is the 0-5-0 steam locomotive, designed in 1926 by BMZ (Bryansk
Engineering Works), in Russia. E-u was the favorite of the engine drivers, because it was
the powerful, reliability and simplicity of nursing and repairing.<br>
In 1935 the 25-years-old engine driver Pyotr Krivonos of the Slavyansk depot 
established the record of the productivity on the steam locomotive E-u N 684-37. It was
a hard problem, because in 1935 Russian railway freight cars had no such reliable brakes 
and couplings. The preparation of this record has given to railway engineers a new  
knowlegdes. This knowlegdes helped to enlarge productivity in all the Russian railroads.
	The Government bestowed Pyotr Krivonos an Order of Lenin upon (one of the highest
State awards in ex-USSR).
