TU8 (Russian: ТУ8) – Soviet, later Russian diesel locomotive for gauge .
Diesel locomotive TU8 (Russian: ТУ8) is used for transportation & shunting services on narrow-gauge railways with a track gauge ranging from to . The TU8 was developed in 1987 – 1988 at the Kambarka Engineering Works to replace the ageing locomotive classes TU6A (Russian: ТУ6А). The cab is equipped with efficient heat-system, refrigerator, radio-set and air conditioning.[1]
The diesel locomotive TU8 (ТУ8) has been used as the basis of three other locomotives:
