Awesome! Just for good measure, make sure and check out the posting "The Latest From Strasburg Railroad Shops"...for the photos and story from October 23, 2012...that shows Strasburg Railroad shops installing the roller bearings on 425 trailing wheelset. Cool. |

For the first time in how ever many decades - the pony truck has a matching wheel set! |

Several questions, what diameter are the wheels, about when where they ordered, what was the lead time and whom was the supplier? Just curious if perhaps you and yours found a supplier with better lead times than the few I know of. It all looks good! |

Is a "pony" truck technically just one axle, and a "lead" truck two plus axles? |

Rob Who was doing the schooling, and what was their basis for saying that it was the proper terminology? Locomotive builder standard term? (If so, were they all the same?) Railroad standards? (If so, did Pennsy call them something totally different?) Some other engineering standard or committee? |

Look out, here comes the "proper name for trucks" debate all over again! |

I believe it was Jack Wheelihan, who knows a thing or two about steam, and the sources he cited (and I later checked) are steam-era engineering and construction documentation. You can Google-up quite a few. I am sure a lot of roads had nicknames for these trucks, but damned if he wasn't right that back "in the day" technical manuals called it an "engine truck." Wowak, I don't see it as a debate, but as a chance to learn. Rob |

Edit: For the first time in how ever many decades - the front wheel guide thingie has a matching set of non holed wheel thingies! |

Wowak, I don't see it as a debate, but as a chance to learn. Rob That's exactly the kind of reference I was asking about. So it would appear, based on multiple engineering manuals from the era, that it was an industry standard term. Fair enough... No debate here, just curious as to the source/heritage of the term. |

Up here in the north, many of us learned it as being an engine truck. Just as a caboose is actually a van, don't ya know! :) Aside from that, engine No.425 is a fine looking machine. Best wishes with her. Thank you. |

Originally supposed to be completed the second week of April but that turned into the end of June. |
