Tep70 East Europeanern Locomotives
Tep70 is the most succesfull passenger locomotive on the eastern side of the European continent. It can be found almost anywhere on the 1520mm rail networks. Although production started in the late Soviet era and was halted for years, new orders have been recieved recently and the BS version of this robust model is manufactured again to meet the customer demand.

RdZ Tep70 number 0217 in Vainikkala, Finland
Tep70 replaced the earlier model Tep60 in production. The Soviet Union bought a Hawker Siddeley "Kestrel" locomotive in 1971, tested it, dismantled it into pieces and further tested the parts. The Tep70 prototype to copy the test locomotive was put together in 1973, but needed several modifications to cab windows, bogies, gear arrangement, dynamic braking, etc. before the production was started. The current model Tep70BS (not a very atractive name addition in English) has minor changes at least to the design.

Estonian Diesel Locomotives

Estonia has a one of a kind mixture of the Eastern and the Western motive power, which you will find on this page. Most of the diesel locomotives originated from the old Soviet Union, and what remained in the Estonian territory at the beginning of its second independence period came to Eesti Raudtee (the Estonian Railways) and several small private operators. Eesti Raudtee (the Estonian Railways) also bought a large number of used C36-7i and C30-7i locomotives from the U.S. and has used them for the last 10 years as multipurpose freight locos, except for local switching.

C36-7i of Eesti Raudtee
Acquired at the opening of the new era for the Estonian Railways the C36-7i locomotives were imported from U.S.A. as a second hand rolling stock to be used with the heavy freight trains from the Russia to Estonian ports.

Built by: General Electric in 1985 for MoPac and UP
Units imported and refurbished: 57, 2002  
Unit numbers: 1501 - 1557
Power: 2800 kW (3750 Hp)
Effect: 438 kN, 96 klbs  
Usage: General freight locomotive, although at home with the heaviest freights is often used for road switching and even local switching.
