[PRR-talk] End of automobile boxcars, beginning of autoracks

[Frederick Ripley]

Folks,

Can anyone offer a date when TTX 85 or 89 ft autoracks would have  
started to show up on the PRR in quantity?
Perhaps late '61 or '62?

Were some of the old automobile boxcars used right up to this time?   
Or had the business, as handled in the old manner,
pretty much dropped away, and was regained w/autoracks?

Thanks, Fred R.
