Abstract
A rail-mounted rail processing machine has at least one traction motor and with at least one working unit for processing tracks, a permanent energy source, an electrical energy storage and a current collector. The components are connected to a common direct current network via power converters. In order to create a rail-mounted rail processing machine that allows low-maintenance and environmentally friendly operation of working aggregates with strongly varying peak loads without having to accept losses in the processing quality, the permanent energy source is a fuel cell which feeds at least one base load of the working unit into the direct current network via one of the power converters. To cover peak loads of at least the working unit, buffer energy of the electrical energy storage acting as a buffer store is feedable into the direct current network via an associated one of the power converters.
