Happy new year! Does anyone know who I can contact that will be able to modify friction bearing trucks with roller bearings in it's journal boxes? How is this done and is this generally expensive? Thanks Drew Meek dm@spangenbergphillips.com |

There may (and I say may only because of heard it second hand) rules not allowing journal box lids on friction bearing trucks converted to roller bearings. If the equipment is historic in nature, you may have to apply for an FRA waiver to bypass the regulation. FRA waivers are common on historic equipment, and it's better to be squared away with the Feds instead of having an inspector find out the hard way... Fiv4HghStk@aol.com |

Good Point, "Lets Roll", the famous well traveled aux. tender has rollers in friction boxes with the lids on. It's a fooler 'till you open the lid. lamontdc@adelphia.net |

Are the roller bearings the type that are sealed? retsquid@tvec.net |

How is this done and is this > generally expensive? > Thanks > Drew Meek I was Car Foreman at Steamtown Foundation and worked out the first conversion there to put roller bearings into friction boxes. It was based on a former AAR Standard Practice. These are presently perfectly legal by the FRA; however, they are prohibited in interchange by the AAR due to the masking of the journal box heat from the hotbox servos. I do not know Steamtown's present iteration of the conversion, but the first two I did left the covers on to make them look old. Biggest reason I went for them then was the massive oil slick being formed on the first mile of the right-of-way from the journal oil from the friction boxes; also, it is proving more difficult to get the brasses and pads to service friction boxes. I have seen versions of the conversion since where the entire front of the box was bandsawed off; this evidently will allow the hotbox detectors to do their thing. Amtrak switch engines in Washington, DC have this conversion. I will do free-lance work for you to engineer and do a conversion; however, I have to fit it arround my present full time work schedule.

The journal boxes on the lets roll tender are cut open underneath to allow the detectors to read. |

I remember a few years ago pulling into Portland Union Station and a person who was not so fond of the 4449 strolled right up to the "Let's Roll" to smell the hot grease on the boxes. I knew exactly what he was up to and just had to laugh as he had no clue that there were roller bearings under those lids! Smokebox "orhf dot org" |

Contact Magnus-Farley@402/721-9540. They have the adapters/kits on the shelf. Also, they can provide you with all requirments and procedures for the conversion. jasonsobczynski@yahoo.com |

I called them and they told me they have not been in the conversion business for over 10 years! Erie Lackawanna Dining Car Preservation Society tstuy@eldcps.org |

They're OK for captive service, but the AAR won't accpet them in interchange anymore, period. |
