| 1939 |
Owing to the enlargement of the electric locomotive repairing workshop the whole steam locomotive and coach repairing plant was removed to the suburb of the city and then reconstructed. |
| 1945 |
Electric locomotive repairing workshop of the plant under the reconstruction was the first in the USSR who modernized the motor-coach train for the voltage of 3000 V. |
| 1949 |
Locomotive repairing plant was put into service. |
| 1957 |
«Locomotive repairing plant» was renamed into «Tbilisi electric locomotive building plant». Reconstruction and enlargement of the plant began. The first electric locomotive Н8-201, in future VL8-201, was produced on December, 30th. So the production of main line electric locomotives in the Georgian Soviet Socialist Republic was started.
|
| 1958 |
In order to accelerate the technical progress Special designers bureau (SDB) was organized as a part of the plant for developing of new main line electric locomotives. |
| 1966 |
Special designers bureau constructed electric locomotive VL8B with sampled-data control for the voltage of 6000 V and 3000 V in contact system for the 1st time in the world. |
| 1970 |
The production of industrial coke-quenching electric locomotive EK-13 was developed. It made the plant well-known abroad. The first industrial electric locomotives were sent to Turkey, India, Poland, Bulgaria, Rumania and CzechRepublic.
|
| 1971 |
The production of electric pilers ЭШ-186 was started. Electric pilers were used not only in the USSR, bit also in Hungary, Turkey, Iraq, India and other countries. ЭШ-186 was presented at many international exhibitions. |
| 1973 |
The first experimental model of coke-quenching electric locomotive EK-14 with thyristor drive and remote control was produced. Electric locomotives EK-14 successfully operate at all metallurgical industrial plants of the former USSR and many countries in the world.
|
| 1974 |
Freight main line electric locomotive VL11 was produced. Electric locomotive ВЛ-11 had two sections worked in multi-unit system. It is also possible to produce three- and four-section configuration. The construction project of VL11 electric locomotive was based on the latest technical inventions. VL11 in three-section configuration is able to transfer trains with the weight of more than 6000 tons. It allows to raise the capacity of railways and to reduce running costs. |
| 1976 |
The prototype of VL10U was put into production.
|
| 1985 |
Special designers bureau of the plant developed the project of VL-15, the most powerful DC electric locomotive in the world.
|
| 1992 |
The project of new electric locomotive E-13 was developed. The same year 2 electric locomotives of such type were produced.
|
| 2000 |
Tbilisi electric locomotive plant in the shortest time designed and produced new DC electric locomotive 4E1. The locomotive rated voltage is 3000 kW, maximum speed – 120 km/h.
4E10 is the industrial modification of 4E1 locomotive. 4E10 is a four-axle freight and passenger DC electric locomotive with electrodynamic braking based on the principle of self-excitation, with the capacity of 2680 kW and maximum speed 100 km/h.
|
| 2005 |
New coke-quenching electric locomotive ЭК-15 was produced under the project of Special Designer’s Bureau of JSC «Elmavalmshenebeli». |
| 2008 |
Projects of new electric locomotives 6E1, 8E1, of the electric locomotive for European gauge are developing. |
