ORER Notes

Discussion, General Notes

• Rebuilt 40' and/or 50' PS-1 boxcar?
• Unknown if dimension change (from 40' to 50') car in 5/1983 means there was a different car with the same number, or if the prior dimensional data was wrong????
• Conversion of 77000 series 50' PS-1?
  Per B&MRRHS Modeler's Notes #39 - yes
