The VR series Sr3 are electric locomotives of the Finnish state railway VR-Yhtymä . The locomotives are the latest of the three electric locomotive series of the state railroad and are based on the Vectron type from Siemens . 80 locomotives were ordered, an option for a further 97 units was agreed. Series delivery began in 2016. The first ten locomotives were added to the official fleet on May 25, 2017 and were used in regular service from June 2017.

history

In 2012, VR published a Europe-wide invitation to tender for a new electric locomotive, which should, among other things, meet the following properties:

  • Top speed of at least 200 km / h,
  • a minimum axle load of 21 tons and
  • a performance guarantee at temperatures down to −40 ° C.

In addition, the manufacturer must have produced at least 20 electric locomotives in the years 2000–2011, which are still in operation and have achieved a mileage of at least five million kilometers.

The major railway vehicle manufacturers Alstom , Bombardier and Siemens submitted a bid for this tender . Only a few manufacturers were able to meet the requirements of VR. The domestic supplier Transtech was unable to submit an offer under these conditions. The operational safety in winter and the maintenance package offered by the manufacturer were named as important factors in the decision. In addition, the large order for 177 locomotives enabled options to make changes in the construction phase specifically for the operator.

In December 2013 VR signed the contract for the delivery of 80 Vectron locomotives with Siemens. The order includes an option for a further 97 locomotives. The value of the contract is around 300 million euros. A trade agreement was signed between the parties in February 2014.

In March 2015, a test locomotive from Siemens came to Finland, which started testing in April. This test locomotive was returned to Germany in September 2016. The Sr3 3302 was the first locomotive to be transferred to Finland in January 2016; the 3303 and 3304 followed in May.

The 3301 was used for test drives in Germany and the Czech Republic until summer 2016 and was brought to Finland in July. The fifth Sr3 (3305) was delivered in September 2016. Numerous test drives were carried out with them until they switched to planning service in June 2017. The remaining five locomotives of the first series were delivered in April and May 2017. Series production began in 2018, and the complete series of 80 units is to be available to the operator by 2026. The life cycle of the Sr3 is expected to extend into the 2070s.

The Sr3 series locomotives replace the Sr1 series that were procured in the Soviet Union in the 1970s and 1980s. In addition, they should help to improve the existing transport problems in winter.

After the pre-series delivery, series production began in summer 2018. Eight locomotives (3311–3318) were delivered in 2018 and three more (3319–3321) were delivered in January 2019. Locomotives 3322 and 3323 were delivered in April 2019. In spring 2019, a driving simulator for the Sr3 series was put into operation in Kouvola, which can also be used for the Sm5 VR series . Sr3 3324, 3325 and 3326 were delivered on September 2, 2019, followed by Sr3 3327 and 3328 on January 30, 2020. Around ten locomotives are to be delivered annually from 2020.

Locomotives 3329–3331 were delivered on April 2, 2020.

Technical Equipment

The Sr3 is based on the Vectron electric locomotive , which Siemens has been manufacturing since 2010. This is based on the technology of the predecessor models Eurosprinter and Eurorunner . The series is used universally at VR, both for passenger and freight transport. The locomotives have an output of 6400 kW, a top speed of 200 km / h and a maximum starting tractive effort of 350 kN. The machines in the Sr3 series achieve almost twice the performance of the Sr1 series and 16% higher than the Sr2 series . An Sr3 is able to move a train with 2100 tons on an incline of up to 10 per thousand. In the test runs, the Sr3 has a top speed of 220 km / h was reached and a load of 5700 tons was carried with a double covering.

The machines are built in the so-called last mile version. Two additional diesel generators enable driving on non-electrified track sections. The diesel engines together develop an output of 360 kW. They are mainly required as a backup power source and for shunting services. With the fuel supply of the diesel engines up to 100 kilometers at 20 km / h, so that it is possible to continue driving in the event of a contact wire voltage failure.

The drive motors are not fully sprung, as was the case with the earlier Sr1 and Sr2 locomotives. The motors are suspended from the bogie frame and the motor shaft is connected to the gearbox via two flexible steel joints. The steel joints are not as flexible as the rubber-sprung connections, but the structure is simpler and cheaper. The forces transmitted to the track are only slightly greater than in the full-suspension version.

The compressed air system of the Sr3 comprises two oil-free piston compressors that can generate a total of 3500 liters of compressed air per minute. The system can be operated safely with just one compressor after a failure. The volume of the main air reservoir is 1 m³. In addition, the water separator and thus the air quality of the braking system are constantly monitored.

The Sr3 is equipped with radio remote control devices. The locomotives have a "Trainguard 100" tracking device that is adapted to the European ETCS access control standard and can work with the Finnish JKV line equipment. They are also equipped with WLAN and DGPS tracking devices. The locomotives are supplied with "Unilink" coupling heads, which correspond to the SA-3 central buffer coupling and are equipped with an integrated screw coupling chain . Loose mixed couplings are therefore not required. With the information system "EKE Trainnet", the locomotive receives constantly updated information about the condition of the doors and brakes of the cars. In addition, the Sr3 is compatible with the Sr2 series and can transport passenger trains with the Edo Transtech control car.

Although the Finnish Sr3 are similar to the rest of the Vectron locomotives, there have been numerous changes to adapt them to Finnish conditions. The driver's cabs were given side windows that were otherwise non-existent; instead of the steps at the vehicle corners, steps and handrails were attached from the entrances, the coupling sockets for the UIC line were made from the end walls below the front windows on the outside of the box sides , in keeping with the Finnish passenger car fleet relocated to the buffers. Because the car bodies correspond to the series version, the openings for the original installation locations of the UIC sockets had to be blindly closed. The bogies for the Finnish broad gauge are manufactured in Graz , Austria . The bogie frames allow the installation of wheelsets in Iberian broad gauge . The remaining components are manufactured in the Siemens factory in Munich .

The following changes were made for winter operation: The locomotive body is thermally insulated, the running gear design prevents snow accumulation, and all external devices and connections are protected from snow. The cooling air inlets were relocated to the roof. The snow plows were mounted on the locomotive and the front of the driver's cabs is reinforced with protective plates in the event of moose accidents. The locomotive is equipped with air conditioning and additional heat blowers. The manufacturer guarantees perfect functioning up to temperatures of down to minus 40 degrees. The dynamic brake acts as a regenerative brake and feeds the braking current back into the contact line network. The locomotive is illuminated using LED technology. The main headlights have a light intensity of 220 000 cd . The vehicle battery is a nickel-cadmium battery with a capacity of 410 Ah.

The first major maintenance of the locomotive takes place after about 1.2 million kilometers. The locomotive continuously transmits wirelessly technical data and diagnoses so that the depot can the scope and schedule of inspection and maintenance plan ahead. An attempt was made to manufacture the wear parts of the Sr3 in such a way that their replacement intervals are as long as possible. 98% of vehicle components can be recycled.

Approvals

From June 1, 2019, the Sr3 series received restricted approval for passenger transport, initially only for the Oulu – Rovaniemi route. The permit was extended to the Helsinki – Oulu route three weeks later. The test runs began on June 3, 2019 on the Oulu – Rovaniemi line with trains IC 413/414 with Sr3 3322 and 3304. The pair of trains IC 121/126 Helsinki – Oulu was first transported on June 24, 2019 by the Sr3 series. After the successful test run, the use of the locomotives was expanded to Pori and Vaasa from mid-July.
