Class E el (Cyrillic script: Ээл) was a Russian diesel-electric locomotive class built between 1931 and 1941. There were three sub-classes but all were very similar. E el-5 was a prototype built in Germany in 1931. E el-9 was a prototype built in Russia in 1932. E el-12 was also built in Russia and went into series production.

Engine
The prime mover was a six-cylinder four stroke diesel engine. The E el-5 had a German built MAN engine giving 1,200 hp (890 kW) at 450 rpm. The E el 12 had a Russian built engine, based on the German design, giving 1,050 hp (780 kW) at 425 rpm. It is uncertain which engine was used in the E el-9.
Electrical equipment
There were five 140 kW Brown Boveri traction motors, connected in parallel. Innovations in the E el-5 included forced ventilation for the traction motors, field weakening for high speed running and rheostatic braking. The rheostatic braking was excluded from the Russian built locomotives, to save weight, but they still weighed several tons more than the E el-5.
Disposal
None of the class is known to have been preserved.
