The Snow Plough.

Roads and Rail.

Basically this is a shovel fitted to trucks and locomotives to push soft snow to one side, but these ploughs could also be employed for pushing sand after a storm. The need for this goes back at least two hundred years, with the onset of the the invention of the engine the design has not changed much!

Today the idea of blowing both snow and sand has been added to snow plough or for sand removal. Railways suffer greatly from such obstacles and from wet leaves that can be the cause of both slippage and derailment. Various forms of weed killer and spray trains have also been designed, along with the removal of dust and rubbish in Metro and underground systems world wide,

Switzerland and Italy have lead the way in these specialist type trains and the British in Metro cleaning systems.

Christmas.

In light of a wet Christmas in the U.K

Perhaps everyone across the northern hemisphere has had some ammount of snow, the U.K. has seen very violent storms, winds rain with severe flooding. Instead of sleds, it has been the boats and inflatables to the rescue.

The inflatable, Zodiac and even the standard rowing boat continues to be part of the invaluable tools used for basic search and rescue across the globe, in all types of flood zones. Little and easy to inflate, they can work in tight spots. Speed is also an essential element to small craft used in this role along with depth levels changing suddenly.

I think we sometimes forget so easily about the very little machines that we use around us, that they do thr very simple jobs and roles. We also tend to forget how much, we could not do without them.
