RUBBER Wheels on RAILS : Indian Railways click here
.
Came across this rare Earth mover surprisingly moving on Rails , with its Normal Rubber Tyres just like the one that moves on Roads.
.
After...
more... a close observation I realized its rear wheels have a ridge in between so that they can move intact on rails with out slipping off .
.
Looks like this is a 2 in 1 Earth mover which can operate on Roads as wells as on Rails. Previously the Earth Movers use to be fitted with special Metal wheels similar to the ones in Trains to move on Rails to carry out operations some what similar to Truck in the video below.
