EZT Newag ED78-030.

The NEWAG ED78-030 train is an Electric Multiple Unit (EMU), which consists of four cars. Serial number 31WE-050; Car numbers EVN: 94 51 2 141 104-1 (PL-PREG A), EVN: 94 51 2 141 105-8 (PL-PREG B), EVN: 94 51 2 141 106-6 (PL-PREG C), EVN: 94 51 2 141 107-4 (PL-PREG D). Year of production 2018. The train was built for the carrier PolRegio, Świętokrzyskie Branch based in Skarżysko-Kamienna. The purchase was made by the Marshal’s Office of the Świętokrzyskie Voivodeship. The train was delivered in December 2018. In April 2025, the train underwent a P4 level repair.

The NEWAG ED78-030 train was painted light gray (white), with gray and orange additions. The doors are orange. Inside, the seats are upholstered in grey with orange accents; headrests and armrests.

The EZT ED78 (EN78) bearing the factory designation 31WE was one of the first low-floor trains built by engineers from NEWAG from Nowy Sącz. This vehicle became the basis for the entire family of trains under the name Impuls. The main feature of the vehicles is the low floor and modern equipment; air conditioning, closed-system toilets, a modern passenger information system and comfortable seats. The vehicle design was created in 2011, and at the beginning of 2012, construction of the first prototype began. The first 4-car EZT was designated type 31WE, it was built at the end of 2012.

During tests on the Central Railway Main Line, on the night of 18/19 February 2013, it set a speed record for vehicles designed and manufactured entirely in Poland, reaching 211.6 km/h. This record was broken two years later, this time by the 5-carriage EZT Impuls 45WE, on the night of 28/29 August 2015, also on the Central Railway Main Line, reaching a speed of 225.2 km/h.

The 4-car Impuls has a lowered floor, a single-space interior and is used for regional traffic, up to about 100 km. The EZT is 74.40 m long. The train weight is about 135,000 kg, depending on the equipment version. Axle arrangement: Bo’2’2’2’Bo’. The total length of the train is 74.40 m. The trains are adapted to operate in temperatures from -25 degrees Celsius to +40 degrees Celsius. The trains are offered in two power versions: Version 1 – 2,000 kW (4 engines of 500 kW, version ED78-030), Version 2 – 1,600 kW (4 engines of 400 kW). The engines are three-phase asynchronous. In the train, the first and last bogie is a drive. An individual drive inverter for each drive bogie was used, in IGBT technology. There are two electric motors in each bogie. The other three bogies, the inter-carriage ones, are of the Jacobs type. The train has two half-type current collectors, which are mounted on the roof of the second and third carriages near the inter-carriage connection. The train fronts are aerodynamic and their external covering is made of composites. The trains are certified for a speed of 160 km/h, although the possibility of running at a speed of 200 km/h is possible.

The ED78-030 train has a toilet, in a closed system, adapted for the needs of disabled people. Each carriage has one pair of automatic doors, activated by a button to open and close automatically. Passengers have access to 230 V and USB power sockets. There is access to wireless WiFi on the train. Some trains have ticket machines and bicycle racks installed.

Train deliveries.

In November 2013, NEWAG signed a contract with the Western Purchasing Group for the delivery of 14 31WE trains, which were designated as the ED78 series. In the period 2013-2015, the West Pomeranian Voivodeship received 12 units of this type, while the Lubuskie Voivodeship received two trains. In 2015, both voivodeships ordered and received one more train each. In the period 2017-2018, the West Pomeranian Voivodeship received an additional 9 trains, while the Wielkopolska Voivodeship received 3 trains. In March 2015, NEWAG signed a contract with the Fast Urban Railway in the Tri-City for the delivery of two 4-car EZT 31WE trains. These vehicles were delivered in the spring of 2016. At the turn of 2016 and 2017, an order was completed for the Małopolska Province, covering 8 EZT trains of type 31WE and 5 trains of type 45WE. These trains were marked with series EN78 and EN79, respectively. They were intended primarily to service trains on the Kraków Główny – Tarnów route and selected connections to the cities of Nowy Sącz and Krynica. EZTs also run on the Wieliczka Rynek Kopalnia – Kraków Główny – Kraków Lotnisko route.

It must be noted that there is some confusion in the marking of individual EZT 31WE and ED78, which was further deepened by the marking of these trains in the Małopolska Province with the EN78 series. Vehicles that have only the factory type marking 31WE are numbered in the order in which they left production. Units marked with the railway series ED78 or EN78, however, have their own numbers, so there are vehicles: 31WE – 001, ED78 – 001 and EN78 – 001 at the same time and they are not the same EZT. As a result of this double marking, in the numbering of vehicles marked with the 31WE type there are free numbers, and others are repeated.

The next two trains with the numbers ED78-029 and -030 were delivered for the Świętokrzyskie Province at the end of 2018. The vehicles were sent to service the Ostrowiec Świętokrzyski – Skarżysko Kamienna – Kielce – Kraków Główny route.

Trains were built with the following designations: 31WE, EN78, ED78. These trains were built in the period 2013-2018. 50 EZTs were built. Production of EZTs with the designation EN78A (Impuls 2) was started, which have been built since 2020 and 9 trains have been built so far. In September 2021, for the Małopolska Province, the EZT Impuls 2, marked with the EN78A series, was put into service. The first two trains were presented on September 29, 2021, in Oświęcim. The Małopolska Province received 9 trains of this type. These trains have 200 seats. A characteristic feature is the additional door leading to the driver’s cabin. Trains have No. EN78A-001, -002, -003, -004, -005, -006, -007, -008, -009.

Own weight 135,000 kg (depending on the version). Engine power 4 x 400 kW or 4 x 500 kW. Engine type TMF50-29-4 TSA, asynchronous. When starting, acceleration 1 m/s2. Speed ​​160 km/h. Number of seats 181 + 21 (folding) – version of the train with 6 pairs of doors. Number of seats 196 + 2 (folding) – version with 4 pairs of doors. Number of standing places up to 256 passengers.

EZT Newag Impuls series EN63A = 36WEa.

In October 2014, Koleje Świętokrzyskie received the first Newag “Impuls” train type EN63A = 36WEa. The train is a 3-car train. By the end of 2014, a total of 3 units were delivered. In 2015, another 3 units were delivered.

As in the case of Pesa “Elf” trains, each car was equipped with only one pair of doors. This solution increases the number of seats in the car, but extends the time it takes passengers to occupy seats in the train. In addition, the train has all the solutions and facilities used in Newag “Impuls” trains.
