L&N 51098 (was NRC Banana Reefer)


#172247 is an M-18 class car built in 1916. This class is an oddity to me as the B&O installed a few thousand M-15 cars with fish belly steel center sillsĀ  in the years just before these M-18 arrived with truss rods and a steel center sill.
It was somewhat common for various roads to buy or build truss-rod box cars in the mid-late Teens after receiving cars with full steel underframes or steel body frames earlier, presumably due to the high cost and low availability of steel at the time. Composite hoppers and gondolas enjoyed a similar revival.
