APD Products The System Behind Locomotive Performance

At the core of every locomotive lies its power generation and transmission system. APD Products deliver this complex arrangement of components, working harmoniously to convert fuel into the massive tractive effort required to move freight and passengers across vast distances.

The system begins with the engine, typically a diesel engine in modern locomotives, which serves as the prime mover. This powerhouse generates mechanical energy, which is then converted into electrical energy by the generator or alternator. The electrical current is then directed to traction motors responsible for turning the wheels and propelling the locomotive forward.
