The electric mine locomotive EL 3 was manufactured at LEW Hennigsdorf from 1951 to 1978 in 791 copies.

The machines were the standard electric locomotive of the opencast mine for the 900 mm gauge in the former GDR, for which 620 units were built. Other locomotives went to Yugoslavia (20), Poland (49) and the Soviet Union (102).

The locomotives were developed with a low overall height for the use of tracks with a severely restricted clearance profile , which was available in the opencast mines, especially under the existing large equipment, and of track systems with poor location quality, which occur particularly in the stops. The driver's cab is arranged lowered between the bogies. For this reason, a close coupling between the bogies, as is the case with the standard-gauge EL 2, is not possible. Therefore, the bogie frames are rigidly mounted around the transverse axis in the bridge frame, the compensation of the height differences between the axles is ensured by additional suspension springs in both bogies, which act as compensating levers. This supports the locomotive at four points. The axles run in plain bearings that correspond to the Prussian type A02. In addition to two standard pantographs above the front end for the standard contact line, the machines are also equipped with four side pantographs for the side contact line in movable and loading tracks. The drive switch with a horizontal ratchet wheel is located in the middle of the driver's cab and can be operated from all sides.
