Re: Caboose Wheel Sizes


Why raise the Center of Gravity on a light car that bobbed around too much anyway.  They could also use the re-machined wheelsets off of 40-ton box cars being scrapped for new 50-ton cars.  It wasn't unusual to see miss-matched trucks on C&O wooden-superstructure cabooses.

I know of NO cabooses that rode on 36" wheels... as has been mentioned previously 36" wheels are for passenger cars (due to high speed and the weight of the car) and heavy (>100 tons) freight cars. Cabooses did not fall into either category.

I can quite confidently state that the PRR's cabin cars all had 33" wheels during the period of this list.  I can only speculate as to the reason why, but the use of modified freight trucks and the servicing of cabin cars in the same location as freight cars would both indicate that 33" wheels make the most sense.  I can't speak for many other railroads, but AFAIK, the READING and NYNY&H both had 33" wheels on their cabooses as well.  In fact, I'm struggling to identify a railroad with 36" wheels on cabooses... any examples?

Can anyone provide information about when and by what criteria the typical caboose wheel size changed from 33 inches to 36 inches?  Was this railroad specific or something that happened across railroads?
