PRR X32 D Question
|
Dave Nelson
My library tells me the PRR X32 d was a rebuild from earlier X32 B and C
cars. with the most obvious external change being a double door car was made into a single door car. Now that it has just one door (just like the original X32), other than the roof contour, are there any other differences between the original X32 and the X32 D? Also, did all the X32 cars use an identical underframe design? Dave Nelson |

All Class X32D had the later "flush" contour roof and a 7 ft 2 in door opening. Be advised that the Bowser HO scale model's door is too narrow as it uses the main door from their 12 ft 6 in opening Class X32A kit. "Also, did all the X32 cars use an identical underframe design?" That's a good question. The design was revised during the production run for Class X32A, widening the door opening from 12 ft 1 in to 14 ft 6 in. All Class X32B and X32C cars had the wider door opening. It follows that the underframe should have been changed as a consequence; this is something that needs to be further researched. Ben Hom |

I suppose the double door could change the location and/or size of the

cross-bearers and maybe something along the side sills too... but the center sill itself would probably be the same for all these classes, don't you think? Dave Nelson -----Original Message-----

I agree. The changes would likely be in crossbearer location, and a comparison of these two builders photos shows an additional sidesill reinfocerment below the doors of the Class X32B automobile car: http://prr.railfan.net/freight/freightphotos.html?photo=BuildersPhotos/X32a_E12406_Side_BillLane.jpg&fr=clX32 http://prr.railfan.net/freight/freightphotos.html?photo=BuildersPhotos/X32b_E15370_Side_BillLane.jpg&fr=clX32 Ben Hom |
