tank car domes


Ray Hutchison
 

Could some one here offer a brief tutorial on the size of tank car domes?  This query comes from a recent comment about wanting to 'cut down' domes to shorter size for specific cars, related to car capacity and ventilation.  Earlier cars had more narrow and taller domes?  Later larger cars had larger but shorter domes (until when)?  Other factors relating to size of the dome?  Venting?

I suspect this information might be of interest to others on the list.
