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.
