Cars were allocated to either the New South Wales Railways or the Victorian Railways for maintenance purposes, and fitted with either 2BS or 2BU bogies respectively. The 2BU bogies were each half a ton heavier than their 2BS counterparts. NSW carriages were maintained at ACDEP while Victorian Railways carriages were transferred to South Dynon, then shifted across to temporary broad gauge bogies and run to Newport Workshops for maintenance, then returned by the same procedure. All PHN and MHN vans were allocated to New South Wales, and were fitted with 2CA bogies which had higher capacity due to 6R axle boxes/130mm axle journals and different secondary spring sets.
