280 Walker railmotors
RM 82 at Seymour, 1978.
These units were a combination of power units built by the Walker Railcar company, Wigan, England: underframes built by Thompsons of Castlemaine: bodies built Martin & King in Victoria, the whole contraption was assembled at Newport workshops.
With a total passenger capacity of 94 (38 1st class and 56 second class), the 280's were used on runs that warrented this large capacity. They were equipped with 2 x 140hp engines, their total length was 118' 10".
They were a fixture on Newport to Werribee runs where they made a connection with the Williamstown train in the days before electrification to Werribee. They were also common on Kyneton services. A 1951 VR newletter reported that a 280 was running a Melb - Wangaratta service stopping only at Benalla and Euroa and another 280 was running the Melb - Mansfield service cutting that journey time by 30 minutes.
