Newag 6Dg is a diesel powered shunter locomotive, modernised by Newag from the locomotive SM42 series by Fablok. The locomotive has a Caterpillar C27 diesel engine, which reduces emissions in accordance with the standards required since 2009. It is equipped with a microprocessor control system and remote control. Compared to the SM42 series, the locomotive appears completely different. [3] [4]
The 6D locomotive was meant not only as a shunter but also for running passenger trains and light freight. The old SM42 design however, dates back to the 1960s and has notable drawbacks due to poor visibility from driver's cab and the V engine which caused noise and vibrations. Over the 30-year production period the locomotive did not have any significant upgrades. The advantage was the excellent traction which was achieved by a8C22 engine at low RPM. There were attempts to modernise the structure in the 1990s, but these did not go beyond the prototype stage (SM42-2000). Only in 2007 Newag Nowy Sącz had prepared a draft for a total modernisation of the SM42 class. [5] This included a high RPM, turbocharged diesel engine coupled with an AC generator in place with a dynamo. [6]
In the railway world the locomotive is called Kiosk due to its streamline and box type structure. [7]

The Stacja Muzeum is located at the former Warsaw Główna PKP railway terminus and is very close to the Warszawa Ochota railway station. The museum's exhibits are divided into permanent and temporary collections — the latter being displayed inside the museum's galleries. The permanent collection consists of historic rolling stock that is displayed on the tracks outside, including one of the few remaining armoured railway trains in Europe. The museum also contains a library which houses many books on the subject of Polish railways.
PKP Class ST40 is a new class of cargo diesel-electric locomotives used by the PKP LHS broad-gauge division and various Polish private operators, designated 311D or 311Da by its manufacturer, Newag. The class is a heavily reconstructed Soviet M62, using only the underframe. The body is new, the main engine is a General Electric GE 7FDL12. Original engines were also modernised, as ED118 A GE. The class is much more economical and modern than a basic M62. The body has external walkways instead of an internal passage connecting the cabs. The first locomotive was modernised in 2007. As of January 2009, there were 20 class 311D completed and six 311Da for PKP LHS, where they are designated ST40.

The Vectron is a locomotive series made by Siemens Mobility, introduced at the 2010 InnoTrans trade fair in four prototype versions: diesel, multi-system, and both AC and DC electric power. The diesel version has been replaced in 2018 by a dual mode locomotive which is powered by electricity on electrified sections of the track and can be switched to diesel mode on non-electrified sections. The Vectron series is reconfigurable and modular, with a Bo'Bo' wheel arrangement, and is intended as the successor to the EuroSprinter family of locomotives. A more affordable, basic version called Smartron was introduced in 2018.
Newag 6Dl is the first locomotive from the SM42 series, modernised to the two storage version. The locomotive is built upon the Newag 6Dg and the Newag 18D, and is able to be powered by electricity. This is the first Newag locomotive which has bumpers to accumulate collision energy.
