Rapid urbanization, with its traffic jams, polluted air, and swelling populations, means rail operators and infrastructure managers must accommodate more passengers in rail networks that are already congested. One solution is to increase passenger capacity on existing networks
Hitachi Energy traction transformers can help rail operators to increase passenger capacity on existing rail networks by using double-deck trains with the best seat-per-train ratio available.
The wear and tear on regional and commuter trains is different from long-distance, high-speed trains. Higher, heavier double-deck EMUs accelerate fast and frequently stop along local and middle-distance routes that connect cities and towns, which puts severe strains on their traction transformers.
The product image shows the Stadler DOSTO (from German Doppelstock, "double-decker"), a bi-level car electric multiple unit commuter train developed by Stadler Rail of Switzerland. It is equipped with Hitachi Energy traction transformers.
