Newag 6Dl


The Newag 6Dl is a locomotive class rebuilt from the SM42 series and equipped with two diesel engines. The locomotive follows the Newag 6Dg and the Newag 18D, and is able to provide electric train heating to the carriages. This is the first Newag locomotive which has bumpers to absorb collision energy.

History

In September 2013, PKP Intercity contracted Newag to convert 10 of its SM42 diesel locomotives with a twin-engine configuration and electric train heating. At the end of 2013, conversion work had started, and was completed in May 2015.

Specification

The modernisation involved work on an entirely new body on the existing chassis, with the use of fuel tanks, which were included in the modernisation. The locomotive uses two Caterpillar C18 diesel engines with a capacity of 563 kW connected to synchronous generators. Each of the units included a new exhaust system, which is supported on the refuge. The engine exhaust systems with the diesel filters are DOC types. Built-in power generators can operate in two configurations: the first uses the power of both motors for traction, the second uses the power of the traction to power the cabin of the train.

Problems

In 2020, there have been problems with the mechanism of some locomotives, which caused the trains to be delayed, being hauled by other locomotives, or in some cases, replaced by bus transport.
