OnEfficiency.StopStart

In principle, OnEfficiency.StopStart is compatible with all diesel locomotives that are already equipped with an electronic control system (e.g. KM-Direkt). Diesel-electric locomotives can also be equipped with the system.

Several locomotives of our customers are already equipped with OnEfficiency.StopStart. The system is in use on the locomotives of Rurtalbahn (G1206), ETF (G1206) and Northrail (G1206).

Voith has been working closely with engine manufacturers on this question since the development phase of OnEfficiency.StopStart. We considered expert advice from Caterpillar/Zeppelin and MTU in the design and parameterization of the stop-start function. The result is a system that respects all the essential conditions specified by the manufacturers for the stop-start operation of modern diesel engines and prioritizes their protection:

• The engine is started and stopped only in the operating conditions approved by the engine manufacturer
• Engine-internal protective functions are not bypassed
• The load on the engine is kept low by only shutting it down after a long shutdown time is detected with the associated low starting frequency

If you would like individual clarification with your motor manufacturer, we will be happy to assist you.

Yes. We offer a standardized solution for G1000 and G1206 locomotives that can be implemented quickly and easily.

For the installation of the standardized solutions (for G1000 and G1206), a workshop time of 2-3 days can be expected.

For other locomotive types, the time required for installation must be estimated individually.

No increased wear was found both in Voith’s test locomotive (standard starter, 1,000 kW engine output, 10BB locomotive), which has been equipped with the Stop-Start system for seven years, nor in the joint pilot projects with our customers.

OnEfficiency.StopStart is already being used by several customers. The system is in use with the locomotives of Rurtalbahn (G1206), ETF (G1206) and Northrail (G1206).

Theoretically, a higher load on the battery system is conceivable, however, no corresponding wear has been detected during the current test projects (Voith test vehicle, customer vehicles).

In addition, we offer a retrofit with UltraCaps, which enables the starting process to be carried out completely via capacitors and optimally protects the vehicle's on-board network against wear.

The system is delivered with an expert opinion and is subject to notification. However, due to the special system architecture, there is no need for further certification.

Yes, OnEfficiency.StopStart also functions without restriction in radio remote control mode.

The components of the system are maintenance-free and durable. The exact service life depends on various environmental factors, but is at least 16 years.

During the development and design of the stop-start system, all relevant railway standards such as EN45545-2, EN50155 and EN50567 were taken into account.

No, OnEfficency.StopStart does not influence the safety deadman circuit.

No, this is not necessary. OnEfficiency.StopStart is designed in such a way that there is no need to interfere with the existing software architecture.

Yes, it is possible to (de)activate the system manually. A permanent deactivation is also possible via an optional mating connector.

After checking various conditions, the system switches the locomotive’s diesel engine off and on again automatically.

We transfer the software for parameterization after commissioning, so that parameter adjustments by the vehicle keeper are possible at any time.

The system can be approved and displayed in all countries. Currently, OnEfficiency.StopStart is installed for customers in Germany, France and the Netherlands. The new ERA approval also simplifies cross-border use.

As the stop-start system only switches off the motor after a waiting time of approx. 3 minutes, we recommend using it in case of a holding time of at least 5-10 minutes. This is also the practice of our customers.

The engine system can be started directly via the traction lever, and the locomotive is immediately ready for operation after the engine has been started. It takes about 3-5 seconds to start the engine. Other systems such as the brake system and GSM-R are active continuously.

A rebuild carried out by Voith is performed in 2 to 3 working days, depending on the locomotive type. This work can be done during maintenance, for example. In addition, the rebuild can be carried out "in service" on customer request, for example on the sidetrack.

An additional control cabinet, compressed air pressure sensor and illuminated pushbuttons are installed in the vehicle. However, no changes are made to the existing vehicle control system, and OnEfficiency.StopStart has no effect on the existing vehicle system. The complete StopStart system can be easily retrofitted at any time. Optionally, the original configuration of the vehicle electrics can be restored with a mating connector. The OnEfficiency.StopStart control cabinet is completely decoupled from the vehicle with the optional mating connector, which may be necessary, for example, before the change display is enabled.

The complete OnEfficiency.StopStart system is maintenance-free.
