Subcritical and supercritical design aspects of bogies are discussed, and a diagram reveals pitching frequency versus speed and relative severity for various bogie designs. It was considered improbable that a bogie could be designed more subcritical than the Commonwealth, so that the problem was one of the feasibility of designing a supercritical bogie. Such a bogie must exhibit a natural frequency of 11.6 cycles/sec. for a maximum speed of 90 mph or 12.4 cycles/sec. for 100 mph. It was concluded that such a bogie would pose no design problems even with a pivot load of 9 ton and a maximum speed of 100 mph.
