| Post subject: | Six wheel trailing trucks |
I know that the C&O and Virginian 2-6-6-6's had six wheel trailing trucks. But I believe that there may have been an earlier application of a six wheel trailing truck on a locomotive (perhaps PRR?) Does anyone know what locomotive first carried a six wheel trailing truck, who built it and when? Thanks. Les Beckman (Hoosier Valley Railroad Museum) midlandblb@cs.com |

Pennsylvania's steam turbine was a 6-8-6. > I know that the C&O and Virginian > 2-6-6-6's had six wheel trailing trucks.

> Pennsylvania's steam turbine was a 6-8-6. But the S-1 was earlier, and it of course had a six-wheel trailing truck (6-4-4-6). I assume you're asking about "normal" locomotives; a large number of suburban tank engines had six-wheel trucks under the tender. The NYC had big 4-6-6Ts that I think look like a J that was telescoped in an accident. It's really too bad the S-1 wasn't preserved! |

Les - PRR's S1 6-4-4-6 duplex was built in 1939 by Altoona, two years before the first H8 for C&O. I believe its design was a joint effort between commercial builders and PRR. |

Dave (and Randall and Don): Thank you very much. The Pennsy S-1 duplex is the locomotive I was trying to think of. Appreciate your help! Les midlandblb@cs.com |

And that brings up a question anout another kind of six wheel truck. I just read about a 3 axel passenger car truck that is supposed to weigh 11 tons. That would be 22,000 pounds for one truck; could this be right? Are/were they talking about the pair of trucks on the passenger car? ted_miles@nps.gov |

A three axle outside swinghanger truck with large central bearing is a massive piece of steel. It's been awile but I think that a disk brake wheelset with bearings and boxes weighs close to 2 tons alone. So 11tons for the complete truck is not out on hand I think that the UP's 6wheel, OSH central bearing truck had a capasity of 90,000 pounds. > I just read about a 3 axel passenger car > truck that is supposed to weigh 11 tons. > That would be 22,000 pounds for one truck; > could this be right?

Paul, Tahnks for the info. I am glad I don't have to pick up any of those parts and pieces! ted_miles@nps.gov |

By actual measurement, while being lifted by a hydraulic crane with a strain gage, typical Pullman heavyweight trucks are 13 tons each. This was confirmed in 1991 when RMNE moved 5 heavyweights out of Jim Bradley's backyard in Stonington, CT. The truckless body of sleeper "Breslin Tower" weighs 57.5 tons. The other cars were slightly lighter. hpincus@mindspring.com |
