The class 245 is the first in a new generation of multi-engine diesel locomotives based on Bombardier's successful TRAXX family. The designation assigned by the manufacturer consists of passenger, 160 km/h maximum speed, diesel-electric and multi-engine.

Since the 1970s, single-engine diesel locomotives have been preferred because the fewer parts made them easier to maintain than twin-engine ones. However, as aspects such as efficiency and environmental protection have become more and more important in the new millennium, the use of multiple engines has again become an alternative. In the class 245, four Caterpillar C18s, each with 563 kW and each with their own generator and cooling system, are used, which have already found widespread use in industry and in road and agricultural vehicles. This guarantees low maintenance costs. In addition, despite their complex design, modern common rail diesels can generally boast of high reliability. The independent control allows individual engines to be switched off depending on the required output, thus saving fuel. The electronics automatically regulate the use of the required engines and ensure that all four are worn out as equally as possible. The latest requirements for exhaust and noise emissions have been taken into account with a closed system for particle filtering and improved insulation.

The first customer for the class 245 was DB Regio, which signed a contract with Bombardier for 200 locomotives over a period of seven years. The plan is for a 245 to replace one or even two 218s at a time. The launch of the locomotives was plagued by many problems which persisted through 2019, leading to many cancellations and delays. These included overheating of the electrical system, clogged particle filters due to software errors or leaks in engine oil and cooling water.
