 Tep70 / ТЭП70 is the most succesfull passenger locomotive on the eastern side of the European continent. It can be found almost anywhere on the 1524mm rail networks. Although production started in the late Soviet era and was halted for years, new orders have been recieved recently and this robust model is manufactured again to meet the customer demand.  Here a Tep70 number 15043987 of the Russian Railways Rzd in Narva Estonia waiting for new assignments in late 2007. Note the curtains in the cabins! To see the larger version, please click the picture. Tep70 replaced the earlier model Tep60 in production. The Soviet Union bought in 1971 a Hawker Siddeley "Kestrel" locomotive, 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. See below for technical details:  To the top of the page
