INGETEAM Traction designs and supplies complete traction, control and auxiliary systems for trams, EMUs, locomotives and high-speed, based on in-house technological developments in the field of control and power electronics, with the goal of maximizing the availability and performance of trains, as well as the offer of comfort and safety. Cooperation with our clients covers the vehicle definition, design and engineering, up to the “turnkey” supply of on-board electrical solutions, for both new rolling stock projects and fleet modernization. 

Our capabilities and experience in the railways sector allow us to offer advanced solutions that contribute towards significant improvements to railway operation, focusing especially on operating costs, reliability, availability, maintenance and energy consumption.


Our priorities in tackling projects are proximity to the client, flexibility, minimization of operating costs, maximizing the rates of reliability & availability of rolling stock and low maintenance costs.

Traction systems
Our offering includes traction converters, electrical machines and auxiliary elements, covering the entire range of catenary voltages (750 Vdc, 1,500 Vdc, 3,000 Vdc, 15 kVac, 25 kVac) and powers, for light tramcars, metros, EMUs, rail tractor units and high speed locomotives. 

Ingeteam Traction’s industrial activity also includes design and manufacture of electric generators for diesel-electric solutions and traction motors adapted to the individual requirements of each project. 200-class insulations are applied in order to minimize weight and size in both open and closed solutions, self-ventilated or forced cooling solutions. 

Auxiliary power supply systems
We offer solutions for all kind of catenary systems: continous voltage catenary of 750-, 1,500- or 3,000-Vdc networks, as well as 1,000 or 1,500 Vac 16 2/3 Hz or 2500Vac 50 Hz for AC catenary systems 

- Light and compact 

- Easy maintenance, thanks to modular design of equipments and advanced diagnosis systems. 

- Equipment for different power ranges. 

- Communication with control system via TCN, CAN, RS-85, and other communication buses. 

- The power circuit switching devices are state-of-the-art IGBTs, specific for traction. 

- The cooling of the auxiliary converter is carried out by forced-air ventilation or water, depending on the output power and the client’s preferences.

Our offer includes battery chargers based on resonant circuits or high-frequency circuits to minimize the space required and weight, and to be integrated with the auxiliary converter itself. 

Vehicle control
Ingeteam Traction’s experience in the development and manufacture of control solutions, for application in different sectors, makes it a leader in the design and manufacture of vehicle control systems and man-machine interfaces. These are based on in-house control electronics platforms that allow for programming in open languages in accordance with IEC Standard 1131-3.

These systems are conceived for use in distributed configurations, minimizing the wiring, and may be connected both by means of TCN protocol (MVB or WTB) in accordance with IEC 61.375-1 and other bus protocols. 

The conception of the vehicle control electronics (VCU) is carried out fulfilling the requirements demanded by railway standards and covers all needs for control, monitoring and communications of any kind of rolling stock, from LRVs, EMUs and locomotives to high-speed locomotives. 

Among said needs, the following stand out: 

- Control of train propulsion and braking. 

- Control of auxiliary converters and battery chargers. 

- Monitoring and driver-assistance systems 

- Management of the train’s on-board systems and their communication with ground station.
 
- Maintenance diagnosis and assistance system.

Finally, we integrate the signalling systems required for vehicle operation (ERTMS or others), as well as the communication elements (GSM-R or others) so as to provide a comprehensive control system for the vehicle. 

Comprehensive on-board electrical system engineering
Our vocation is to work side by side with our client throughout the various phases of the project. From the initial phase, we contribute with our experience in the analysis of the system’s performance, and starting with the original system in the case of renovations, right up to the final phase, to offer optimal solutions in terms of both performance and cost.

In this process, all the necessary simulations are carried out to guarantee the proper power specification of the traction system in keeping with the track profiles, the aerodynamics of the vehicles and acceleration requirements. 

Likewise, we execute the specifications for all the on-board electrical components, traction system, control, auxiliary power supply, communications, signalling, security and comfort, integrating said systems in the engineering of the train. 

Our engineers proceed to program the vehicle’s various control systems, its commissioning and subsequent approval, thus supplying a “turnkey” project.

Maintenance
As part of a comprehensive offering, our commitment is to guarantee the best service during operations. 

We provide highly qualified and experienced teams and the necessary means for the maintenance of the electrical systems installed aboard, to ensure that the specified ratios of reliability and availability are complied with. 

Our extensive offer of services and systems maintenance is supported by our mastery in developing and executing complex projects, and qualified technical teams.

Modernization of rolling stock
The high costs of maintenance and operation of the fleet of vehicles, as well as insufficient dynamic performance, frequently oblige the operator to make investment decisions on the modernization of the equipment. 

Ingeteam Traction offers operators the possibility of renovating the electrical traction and control system of the rolling stock, obtaining the advantages contributed by our modern traction systems, but with a lesser investment and a reduced project execution time. Our proposals are especially suitable when the mechanical components of the fleet are in good condition. 

The advantages obtained in this type of project are: 

• Greater availability
The new alternate-current traction systems offer greater reliability than the traditional direct-current systems. This, along with the lower number of necessary electromechanical elements, allows for greater fleet availability, improving the returns on the investment in rolling stock.
• Lower maintenance costs
Alternate-current systems, especially asynchronous ones, require less maintenance since there present no problems with brushes, collectors, camshafts, contactors and electromechanical parts in general, also a lower cost for replacement parts for the alternate-current systems, allows the fleet maintenance costs to be significantly reduced.
• Lower energy consumption
The possibility of catenary regenerative electrical braking means important savings in operational costs, taking into account the evolution of energy costs.
• Greater comfort
The precision in traction control offered by the new traction systems contribute with jerk control, leads to improved comfort for the passenger.
• Improvement of dynamic performance.
The dynamic performance of rolling stock improves thanks to the remodelling of the traction system, facilitating the use of rolling stock on lines with greater demands or the reduction of operational times, given that the new alternate-current systems allow for greater performance in the same space.
• Extension of the useful life.
The renovation of the traction system allows the rolling stock’s useful life to be extended for the purpose of optimizing the existing fleet.

Energy recovery systems
Our development recovers kinematic energy in railways systems, solving the existing energy recovery limitations and being integrated into current substations without modifications of the existing systems, including the transformer. 

The studies carried out in metropolitan networks confirm that is possible to save30 to50% of the energy consumed by the system.
