The Dayton-Phoenix Group Mission is to help move freight around the world through the innovation, manufacturing and servicing of heavy freight and transit components and systems.


The year was 1939. By building components for our first locomotive customers, Dayton-Phoenix Group began a powerful and successful journey that has led to our position in the industry as a broadly respected supplier of quality components and systems for railroad and industrial customers everywhere.

Since our beginnings well over 50 years ago, Dayton-Phoenix has stayed on track as a leading supplier of electrical and locomotive components for the industrial and railroad markets. Today, we continue to enjoy our hard-earned reputation for quality... staying at the leading edge of our expanding markets of choice... delivering products for customers across the nation and throughout the world.

Dayton-Phoenix Group Acquires Dynamic Corporation

Dynamic was founded in 1954 in Hammond, Indiana making braking resistors for Electro-Motive Division (EMD) of General Motors in the export market. It moved in 1962 to Lafayette as a result of rapid growth and in 1983, Dynamic introduced domestic resistors for both EMD and General Electric locomotives. Dynamic Corporation became the supplier of resistors for all new GE locomotives in 1986 and started producing resistors for the transit and AC locomotive markets in 1993 and 1994. Dynamic became certified to the ISO 9001 quality standard in 1997. Dynamic was purchased in 1999 by Amsted Industries, an industrial manufacturer serving three major markets: railroad, construction and building, and general industrial. In 2000, Dynamic was acquired by Dayton-Phoenix Group, Inc.

Today, as a manufacturer of dynamic braking resistor for diesel electric locomotives, the Company is an industry leader in its technological know-how in product development and Company operating systems.

Dynamic was the first high-capacity resistor manufacturer to obtain engineering approvals as an OEM supplier for both Electro-Motive Division and Diesel Division of General Motors and General Electric for new locomotive production and aftermarket service parts manufacturing. Now, DPG is a Certified Supplier to both General Electric and EMD.
