With State Highway 87 closed since Sunday, travel in and out of the area has been impossible.
Strath Taieri Community Board chairman Barry Williams said "cabin fever" was setting in and his wife, Lorna, had organised a special delivery of supplies for Middlemarch locals.
So the Taieri Gorge Railway, along with 38 passengers, transported bread, milk, pies, eggs, meat, farm equipment and copies of the Otago Daily Times to Pukerangi yesterday.
Waiting for the train were a group of 4WDs and people grateful for the help.
"It's ... brilliant," Mr Williams said.
Shearing contractor Bruce Thomas was glad he would be able to feed his gang of 18 shearers who were "running out of food".
He had to dig his tractor out five times to make it to the train and was "bloody sick" of the weather, but admitted "it could have been worse".
Supplies also went to local store Vilo Fait after owner Dave Thomson travelled to Dunedin via beach buggy and the train on Tuesday and hitched a ride back yesterday.
The trip was "pretty hard case" as the beach buggy broke down, was fixed with nylon line from a weed-eater, and twice had to be towed out of snow by a tractor, he said.
But with stock running low in the store and at the cafes and restaurants, the trip was necessary.
However, Mr Williams had not heard of anyone having any "drastic problems" as power was on, roads were clearing and plenty of warning had been given before the storm.
"The old bush telegraph is working pretty well. We are pretty right."
Dunedin city councillor Kate Wilson, who lives in Middlemarch, said people in Middlemarch were handling it well.
"We are a resilient bunch up here," she said.
The state highway is expected to be clear by today.
