OnEfficiency.StopStart FAQ


Are you ready for the decisive step towards more efficiency, but still have questions about OnEfficiency.StopStart? You will find your answer here.

With which locomotives and vehicles is the OnEfficiency.StopStart compatible?

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.

Does OnEfficiency.StopStart lead to higher wear on the starter, engine or other components?

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.

Are there any references?

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).

Does OnEfficiency.StopStart place a greater load on the battery system?

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.

Do I need a further certification when equipping a locomotive with the stop-start system?

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.

Does OnEfficiency.StopStart also work in radio remote control mode?

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

What is the lifetime of OnEfficiency.StopStart?

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.

Does OnEfficiency.StopStart meet all standards?

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.

Does OnEfficiency.StopStart have an influence on the safety deadman circuit?

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

When using OnEfficiency.StopStart does the software of the vehicle control system have to be adapted?

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.

Can OnEfficiency.StopStart be switched on and off manually?

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

When does OnEfficiency.StopStart become active?

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

Activation sequence of OnEfficiency.StopStart

Can the parameterization of the stop-start system be adjusted after commissioning?

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

In which countries can OnEfficiency.StopStart be used?

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.

At what stop time is the use of the automatic stop-start function appropriate?

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.

How long does it take for all systems to be up and running again?

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.

How does the installation of the stop-start system by Voith proceed?

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.

What changes are caused by the installation of OnEfficiency.StopStart on the vehicle?

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.

At what intervals must the stop-start system be serviced?

The complete OnEfficiency.StopStart system is maintenance-free.
