REO’s takeover of the company Nieke Elektroapparate GmbH Berlin in 2004 still ensures that customers of railway equipment, some of which was mass-produced more than 40 years ago, can still obtain spare parts from REO. However, these devices are not simply available. They are also revised beforehand by our engineering team and overhauled in terms of applicable standards and material selection. Smooth individual material procurement and subsequent production are thus made possible, and the finished products can go back into use for many years.
