Newag Impuls is a family of standard-gauge electric, diesel and bi-mode (hybrid) multiple units manufactured by Polish railway rolling stock manufacturer Newag. Manufactured in several versions, they differ in the number of cars and purpose. The company offers several versions: electric 2-car (types 37WE and 37WEa), 3-car (types 36WE, 36WEa, 36WEb, 36WEd), 4-car (type 31WE), 5-car (type 45WE) and 6-car (type 35WE) trainsets, and also diesel and bi-mode 3-car (types 36WEhd and 36WEh, respectively) ones.

By the end of 2020, 190 Impulses were ordered.

Description

The Impuls family of trains are low-floor multiple units equipped with a full interior monitoring system, air-conditioning, passenger information system and can have ticket dispensers if requested.

Their interior is suitable for the needs of passengers with reduced mobility. It features sloping floors, folded steps, broad aisles and a designated space for wheelchairs and bicycles. In the vehicle, motor bogies are used as well as Jacobs bogies (mounted between each two cars). The bogies have a modern gear system and two-stage spring suspension systems that effectively muffles vibrations, thus enhancing comfort while travelling. [1]

The trains can be built in various configurations. The two-car variant is known as "37WE", three-car "36WE", four-car "31WE", five-car "45WE" and six-car "35WE". The trains can have interiors equipped for commuter and suburban service but also for use on long-distance routes. [2]

The first design was launched in 2012. One of the trains, produced for Koleje Dolnośląskie, broke the Polish speed record of 211 km/h (131 mph) in 2013 on the test track, on 7 September 2015 a Newag Impuls 45WE unit for Koleje Mazowieckie once again topped this record with what is now the current one, 226 km/h (140 mph), which makes it the fastest passenger train produced in Poland.

Newag launched a second generation of the design, named Impuls II, in 2017 with an order of 14 trainsets from Łódzka Kolej Aglomeracyjna. [3]

The bi-mode version's top speed is 120 km/h in diesel mode and 160 km/h in electric mode. [4]

2023 reveal of sabotage

In December 2023, it was revealed that Newag Impuls software had code that purposefully caused breakdowns of trains that were serviced by non-Newag workshops, were inactive for 10 days or fit in other arbitrary conditions, which has been likened to Dieselgate software manipulation. This was discovered by reverse engineers hired by Koleje Dolnośląskie and confirmed by former Polish minister of digital affairs Janusz Cieszyński. [5] [6]

A streamliner is a vehicle incorporating streamlining in a shape providing reduced air resistance. The term is applied to high-speed railway trainsets of the 1930s to 1950s, and to their successor "bullet trains". Less commonly, the term is applied to fully faired upright and recumbent bicycles. As part of the Streamline Moderne trend, the term was applied to passenger cars, trucks, and other types of light-, medium-, or heavy-duty vehicles, but now vehicle streamlining is so prevalent that it is not an outstanding characteristic. In land speed racing, it is a term applied to the long, slender, custom built, high-speed vehicles with enclosed wheels.
