I went digging through my photos and found a bunch of old gems, both of the fert works in New Plymouth, the port and the ones below showing some of tonnages we used to move out of Palmer Road, to supplement the ones in my Sunday Waffles post.
At the end of the branch, the shunt will run around the containers in the Kapuni yard and take them back to Palmer road to push them into the sidings. This move was necessary when the "loop" in the Petrochem siding was full and there was no room to work the sidings with the loco on the west end of the rake. The P+O containers behind the loco have been pushed out of the Lactose siding by their little Price.
I have got a bunch more photos of the port, and of the various locos that have worked at the fert siding in New Plymouth over the years sitting in the draw, which I hope to scan soon..... best to strike while the irons hot, on a roll and all that :-)
