Modernisation

As a result of the modernisation the Soviet-produced internal combustion engine was replaced[2] with a US drive unit that meets the emissions standards for UIC IIIa.[3] The power output has been raised from 0.88 MW (1200 hp) to 1.55 MW (2100 hp), which makes the new version suitable for shunting. The driver cabin has been changed based on Newag 6Dg and, combined with lower height of prime mover compartment, visibility from the cab has been improved. Air conditioning (KL20 with a power of 4.3 kW), GPS, and NES microprocessor control system were installed in the driver's cab.[4] The reused components undergone major repairs are: rigid frame and boogies, the brake system, which had been fitted with four cylinders per boogie, spring brake system, and traction motors, which are subjected to pressure-vacuum impregnation. The power generator consists of an internal CAT 3512C engine with main generator and auxiliary generators. The locomotive has a microprocessor control, modular braking system array with rotary-screw compressor, and the AC-DC converters.[5]

gollark: Yes, but that's not all of it.
gollark: I think all these nuls are doing something weird to my terminal.
gollark: I wonder if it's worth just trying to bruteforce it, since I can't make this lua decompiler work.
gollark: Looks like it's doing something almost but not quite hexadecimaly.
gollark: This looks like bytecode.
