Maintenance depot Cottbus
Your competence centre for diesel-hydraulic and diesel-electric rolling stock and their components.
The Cottbus maintenance depot was founded in 1874. We conduct regular maintenance (general overhauls) and (accident) repairs as required by our customers.
The maintenance depot has specialised in conversions, for example the equipment of rolling stock with new engines or modernisations, and creates complex vehicle conversions. An example of such a conversion is the conversion of track recording vehicles for DB Netz AG.
Two locomotives are currently being upgraded with hybrid drives at the Cottbus maintenance depot.
In addition to the work we carry out at the maintenance depot, we also offer an on-site maintenance service. This means that vehicles do not need to be transported and vehicle downtimes are kept to a minimum.

Innovative approaches at the Bremen maintenance depot
HELMS project (Hybrid Electro-Mechanical Shunter)
As part of the HELMS project at the Cottbus maintenance depot, an innovative hybrid concept for energy-efficient power transmission is being implemented on behalf of DB Cargo on two Class 294 prototypes. It involves the replacement of the conventional hydraulic transmission with a hybrid planetary transmission, which in turn ensures a future-proof energy management system. The expected reduction in fuel consumption and CO2 emissions is 20%.
Class 335 re-engining project
In this project, Class 335 locomotives are equipped with new Caterpillar engines of the type C9.3 with an output of 224 kW. The six-cylinder in-line turbocharged engine allows for a more efficient use of the locomotive compared to its old diesel engine of the type MWM D601-6.
To comply with the strict emission values of emissions limit stage IIIB of the emission standard, the locomotive is retrofitted with an active exhaust gas treatment module (CEM). CEM is a flexible, modular system designed by Caterpillar that includes several components. Among other things, it includes a diesel oxidising catalytic converter and diesel particulate filter.
- Complex modernisation of 53 electric locomotives for Vattenfall AG
- Equipment of main-line diesel locomotives (Class 233) and diesel shunting locomotives
- (Class 29x, Class 36x, Class 298, Class 335) with new engines for DB Cargo
- Retrofitting BR 266.4 (Class 77) with a Wankel on-board power supply system
- Conversion/modernisation of RAILAB measuring trains for DB Netz AG
- Conversion/modernisation of track inspection vehicles for DB Netz AG
