Is there any effort made by manufacturers to develop new and improved types of traction transformers for trains? If so, what are they? Answer according to: Over the past decades, transformers have been used in railway traction, as it was considered to be the most prominent alternative to the conventional fossil-fuel-based traction systems. Today, it is one of the most vital components of an electric traction system as it feeds power at safe voltages to essential train functions like traction, lighting, heating and ventilation, passenger information, brakes, signalling and communication. Traditionally made of iron and copper, these transformers are among the heavier components on a train. It tend to occupy more space and weight resulting in increase in train axle load and need for additional energy. Therefore manufacturers globally are developing new type of traction transformer with improved both in structure and performance for application in freight and passenger locomotives, tram-trains, regional trains, and high-speed trains. Traction transformers are mostly design and manufactured in accordance to specific railway system and based on detailed parameters. The system can be divided into two major groups, AC (alternating current) and DC (direct current) systems.
