We are the designer of the original General Electric model
GP-1200 Transition Test set, commonly known as a Motor-Generator (M-G) test set. This model was designed nearly twenty years ago specifically for the railroad industry for testing locomotives.
Please consider us for service on your existing test set. We can provide testing and repairs as well as safety and operational upgrades to these instruments. This can be provided as no other vendor can as we are the sole holder of all technical documents to the internal designs and workings.
