Questions about inner bearing axle trucks. |

Posted by JournalSquare-K-Car on Tue Jul 29 21:26:53 2008, in response to Re: Can anyone ID this car?, posted by Joe Saitta on Tue Jul 29 12:17:50 2008. So now i am wondering...when did the inner bearing trucks get developed, and why? What are the advantages? I can imagine it is easier to swap out the wheels, but are there other advantages, like a better ride, or less rail wear? Are there anyy disadvantages? I can imagine they can't take as heavy of a load, because all fright trains use outer bearing trucks.Also, what are hollow axles, why were they developed, and what are the advantages over solid axles? Thank you in advance. |
