IRG handles a complete line of spare parts for railroad applications.   For years, our companies have been both suppliers to and customers of the primary locomotive manufacturers including Electro-Motive Diesel, Inc.,  General Electric, ABB, Siemens, and Alstom.

We supply replacement components of our own manufacture for Electro-Motive Diesel, Inc., General Electric, and Alco locomotives.  With many locomotive spare parts no longer available from the OEM, IRG can provide the manufacturing services including reverse engineering to help a locomotive owner solve their spare part challenges.

If you know the part number required, please complete a quote request form for a complete quotation.

Kitting Program

IRG's experience with the supply of locomotive components has been focused on providing our customers with complete sets of spare parts in "kit" form for their repair application.

Our kitting program began with our manufacturing of complete insulation material kits for traction motor rewinds.   Years ago, we supplied complete insulation spare part kits for traction motor rewinds to General Electric's facility in Saint Louis.  

Today, our kitting program has since expanded to include not only traction motor insulation components, but a wide range of electrical and mechanical components for locomotive repair.

IRG locomotive spare part kits are assembled with an exacting attention to detail allowing our customers to single source their spare part requirements knowing that one company can provide a complete solution for quality components delivered on-time.
