'Keeper of the Flame' Martin Phippard has sent me these pictures 
"Apparently his engineering skills and proximity to the South Pole (you can't get much farther South than Tassie!) made him the perfect candidate for such a venture. I know that the Noddy is not a truck in the true sense of the word but it is a load carrying vehicle doing a truck's work in extremely hostile conditions." And here's a picture of it at work too...
Starting off with this Tucker Sno-cat which is expected to haul freight at temperatures as low as -90°C in places where a vehicle breakdown came be a matter of life-or-death...literally. At the Halley Antarctic station, all the vehicles are tracked, giving all-year-access around the Brunt ice shelf, whilst at the Rothera station a mix of wheeled and tracked vehicles deal with the ever-changing summer conditions---when the snow recedes it leaves bare rock around the base location.
All the diesel-engined vehicles require pre-heating before they can be started in the low temperatures; they also use alternative fuels (like JET A1 aviation fuel) to stop the waxing of regular diesel fuels and all are fitted with six-speed Allison automatic boxes which are easy to drive and less prone to damage. A dozen Tucker Sno-cats transport personnel and tow sledges of up to eight-tonnes containing supplies from the BAS's main logistics support ship, RRS Ernest Shackleton. Powered by Detroit Diesel or Cummins 6BT and QSB diesels the Sno-cats' 170hp engines drive through the Allison auto to four tracks, with steering provided by turntables fitted to the axles.

BAS vehicle managers regularly spend the entire winter season at either Rothera or Halley station and in the winter months they naturally can't afford to have on break down.
BAS always has emergency vehicles on standby and with limited service facilities in Antarctica and the nearest workshop thousands of miles away it's essential that maintenance requirements are kept to a minimum. And on those rare occasions that a problem can't be fixed on-site, vehicles are shipped back to the UK to the BAS's Cambridge workshops or the supplier."
This shot will give you an idea of how bad conditions can get....all pictures from either the BAS or Allison....
And here's a Sno-cat in one of the Antarctic service 'hangars'...
