A railway truck leveling valve arrangement for improved railway car floor height control comprises a pneumatic level regulating valve, a rigid, lightweight bar, and a leveling valve linkage. The level regulating valve is connected to and mounted above a secondary air spring suspension. The rigid, lightweight bar extends between the axleboxes of the railway truck wheelsets, the railway truck wheelsets being coupled to a primary suspension. The leveling valve linkage connects the level regulating valve and the rigid bar. The level regulating valve senses spring deflection in both the primary and secondary suspensions and signals the secondary air spring suspension to compensate for both deflections. Consequently, the correction of the overall railway car floor height by the secondary suspension provides more precise car floor to station platform height control.
