| Post subject: | Looking for EMD GP-9 Electrical Schematic |
The Belton, Grandview and Kansas City Railroad is looking for an electrical schematic / diagram for our GP-9. Our GP-9 is specifically an ex-C&O, then ex-B&O unit, 6142, then ex-Huron and Eastern 102. It has electro-pneumatic control, Dynamic Brake and was built to Spec #103.2-10, if that helps. Any help or suggestions would be appreciated. Needless to say the generic (and non-dynamic brake) chart in the back of the GP&9 book helps, but is not correct. Thank you! |

Matthew- I might suggest giving VMV or whatever they are known as now, or some other rebuilder. I went to them with a similar request and they produced a wiring diagram for ex-N&W GP-9's. They seem to have a wide variety of them. Good luck. Ned |

Probably not much help, but it looks like the wiring diagram from the factory would be EMD 8234924. I have one SP GP9 schematic with DB, but it has magnetic switch gear and SEARCH. |

About 15 years ago, I purchased a schematic from a parts distributor for EMD. I believe they were located in Louisiana, but I'm not sure. I had called La Grange and they directed me to their distributor. Maybe someone can fill in the blanks for me. |

That was most likely RSI in Houma, Louisiana. They no longer exist. The archives with prints from this era were put into document storage a couple years ago. If anybody at Progress Rail still has a copy it is pure luck at this point. PC |

Does this locomotive have a cash register style control stand? or a barrel style? Field loop Dynamics? or up graded with the more standard arrangement for dynamics? We have a B&O print for the barrel control stand that matches our C&O GP9 very close. We have a B&O print for out B&O engine with a cash register stand that matches our C&O GP-9 good enough. We have nothing that shows how they modified the field loop dynamic brakes to the current configuration. If you ever find any thing on the C&O stuff we would be interested to know more. If you don't PM and I probably have enough B&O stuff to keep you moving for some time. Ben True DGVR |
