Schaffner brings a wide experience in the traction rolling stock transformer business. Since decades, we design and produce successfully high quality devices and solutions for the railway market.

Our traction rolling stock transfomers stand for exceptional reliability and superior product attributes. Shock and vibration resistance, fire and smoke proof, low weight and a very compact custom design are just a few of our quality characteristics.
