Where does the 42% come from?
For the year 1960 according to the ICC's Monthly Operating Statistics of Large Steam RR's, 18.2% of the daily average of all freight cars on the B&O were unserviceable (1960 average - 95,396 average total cars on line daily; 17,171 cars unserviceable). Of the 95,396 average total cars on line, 60,311 were owned by the B&O, and 35,085 foreign owned. If we assume that 1% of the foreign cars on line were unserviceable, then 16,770 B&O cars would be unserviceable which then translate to 19.0% of B&O's total 12/31/1961 being deemed unserviceable.
Granted B&O's 18.2% was an awfully high number - even more than the PRR's 13.8% - the national average unserviceable percent was 7.7% in 1960.
Regarding B&M's "contributions" to the B&O in 1949 the B&M leased 100 1928 quad hoppers and 100 drop bottom gons to the B&O for five years. The B&O renumbered the hoppers into their #2000-2099 series and the gons into their #36000-36099 series. The B&O returned 99 of the hoppers and all 100 of the gons to the B&M at the expiration of the lease.
