Sometime in that period, 1447M was coupled with Harris motors 794M and 797M, with transition vans 320 and 329D (as 797-320-1447-329-794). The two Harris cars were fitted with rail greasing equipment for tight curves, and the five-piece train made regular runs around the electrified network. While 1447M was in all-over yellow and the two Harris cars in similar livery but with green/yellow Met stickers along the sides, the two D vans were in normal V/Line orange livery; the only alteration was the fitting of screw couplers at one end each to allow coupling to the Tait carriage.
