Question for the folks that follow this type of stuff.
When did the transistion of wood side reefers to steel side reefers begin. Since there had to be thousands of wood side reefers when the first steel side reefers were released how long did it take for the wood side reefers to disappear from active duty. I am guessing that for a period of time the RR's were running an equal mix of wood side reefers and steel side reefers.
