As a key component of low-floor trains, independent wheelsets suffer from issues such as lack of steering performance, wear, and noise due to their structure, which are major factors constraining the development of low-floor trains. Therefore, this paper established a rapid control prototype (RCP) test platform by utilizing the existing rolling test bench for single-axis bogies with independent wheelsets and combining it with the dSPACE system. Two active steering control strategies were proposed and verified through steering performance validation of independent wheelset, joint simulation validation of Simulink and SIMPACK, and hardware-in-the-loop simulation bench experiments of active steering control strategies. The experimental results show that the independent wheelsets themselves do not possess the curve centering ability, but when active steering control is added, the independent wheelsets can completely eliminate lateral offset. Both proposed active steering control strategies enable the independent
