A method for performing a technical process in which application programs are executed redundantly in a plurality N of computing instances and, on the basis of an MooN system, wherein M is at least two and N is at least three, a comparison of the plurality N of results of the redundant execution of the application programs is performed in a voting. When a minority of the results is different from a majority of the results with identical content, the minority is excluded during the performance of the technical process, is repaired with a state copy of one of the intact computing instances and reintegrated into the process. There is also described a computer program product and a provisioning apparatus.

A method determines the energy consumption of a rail vehicle during a test drive. The method includes: a) providing a locomotive system having a brake locomotive component and a test locomotive component, b) providing a test route, c) providing basic data for the test drive having information about the train composition, load, route profile and timetable, d) determining driving data from the basic data, and transmitting the driving data to the control system, e) determining braking data from the basic data, and transmitting the braking data to the control system, f) carrying out the test drive with the locomotive system on the test route and measuring the energy consumption of the test locomotive component while this is controlled in accordance with the driving data and is simultaneously braked by the brake locomotive component in accordance with the braking data. A corresponding system is provided for implementing the method.
