Newag 15D/16D
Newag 15D/16D is a cargo locomotive (type 15D - PKP ST48 series) or broad gauge (type 16D) diesel locomotive rebuilt by Newag in Nowy Sącz in Poland, which is a deeply modernised SM48 (Soviet TEM2) locomotive.

Modernisation

As a result of the modernisation the Soviet production internal combustion engine was replaced, with a US drive unit that meets the emissions standards for UIC three. In the modernisation the rate of power has been raised from  0.88 MW (1200 hp) to 1.55 MW (2100 hp), which makes the new version of the Tamara as a locomotive. The height of the driver cabin of the Newag 6DG has been raised, to improve visibility while driving. Air conditioning was installed in the driver's cab (KL20 with a power of 4.3 kW), a GPS and microprocessor control system NES. The components undergone major repairs and the brake lever system had been fitted with four cylinders, a spring brake system and traction motors, which are subjected to pressure-vacuum impregnation. The power generator consists of an internal CAT 3512C combustion engine, with a main generator and auxiliary generator. The locomotive has a microprocessor control, antilock braking system, brake system array, screw compressor, and the AC - DC locomotive gear systems.
