Yes and multiple steerable axles were made possible thanks to Rudolf Akerman's steering principle dating to 1818 later applied to almost all motor vehicles once they came along. Some of the early steam traction engines were still steered by parallel steering having a single rigid axle which was rotated like wagons being turned by a tongue. The Akerman principle steering can be applied to vehicle with 1 or a 1000 steering axles the angularity of the turn radius being slightly different between the inner and outer wheels proportionally changing with each subsequent axle
