TEP70, especially its experimental batch (first 7 locomotives), incorporated some features of British Rail HS4000, for example, its bogies and some elements of driving control equipment. Later batches of this locomotive incorporated some design features from TEP75 experimental locomotive and predecessor TEP70. Final batches, produced until 2006, also had several important improvements. The TEP70 diesel locomotive has been used as the basis of two other sub classes, the TEP70BS and the TEP70U.
