B-70-33 Box Cars
A roster of the B-70-33 class box cars is provided as follows:
BKTY 20200-20311 49'-1" 4650 ft3 AC&F 1966 BKTY 20656-20825 50'-2" 5040 ft3 AC&F 1966 MKT 8600-8699 60'-9" 6450 ft3 Evans 1967 MKT 8700-8799 60'-9" 6450 ft3 Evans 1967 MKT 11400-11749 50'-6" 4980 ft3 Evans 1967 MKT 11750-11874 50'-6" 4980 ft3 Evans 1967 MKT 11875-11992 50'-6" 4980 ft3 Evans 1967 MKT 11993-11999 50'-6" 4900 ft3 Evans 1967
These box cars were built as listed above and were all stenciled with the SP class designation of B-70-33 even though they were very different in design. This was a deviation from typical SP practice of assigning a new class designation to each different car design or order.
Photos of each of these groups of cars can be seen in the book Frisco/Katy Color Guide to Freight Equipment by Nicholas Molo.
