X23 and R7 floor stringers


Bruce Smith
 

Folks,


An interesting question has arisen over on the PRRPro list in the X23 and related car project.  It appears that the X23, R7 and likely the other related cars were built without longitudinal stringers. These appear to have been added to the X23 at some point, being placed between the cross bearers, instead of above them. Was this modification ever made to the R7 refrigerator car, either while in PRR service or after transfer to FGE? Leaving the full span between the centersill and side sill unsupported seems like something that would have needed correction in all members of the class.


Regards,

Bruce
