The bogie had a conventional bolster suspension with swing links carrying a spring plank. ==== B4 bogie ==== The B4 bogie was introduced in 1963.
Some of the B4-fitted Mark 2s, as well as many B4-fitted Mark 1 BGs were allowed to run at with extra maintenance, particularly of the wheel profile, and more frequent inspection. ==== BT10 bogie ==== The BT10 bogie was introduced on the British Rail Mark 3 coach in the 1970s.
The EMD version, designated HTCR, was made standard equipment for the SD70 series, first sold in 1993.
GE introduced their version in 1995 as a buyer option for the AC4400CW and later Evolution Series locomotives.
These include the SUW 2000 system from ZNTK Poznań. === Cleminson system === The Cleminson system is not a true bogie, but serves a similar purpose.
Thus EMD introduced the HTSC truck in 2003, which basically is the HTCR stripped of radial components.
