Above is an old ice breaker exhited at Foxton. This could be manned by up to fifteen men and pulled by 8-12 horses! The men would rock the boat from side to side in order to break the ice, keeping the commercial traffic moving in all weathers.
Here is second iceboat.
Looking down the inclined plane to the lower basin which is now used for moorings.
Looking across the remains of the top of the inclined plane. There are three supporting/guiding rails per plane and two planes allowing one boat to be lowered and one to be raised at the same time. The narrowboats would enter a caisson, (super sized elongated bucket of water) and be lowered to the bottom of the plane by the miracle of steam power. This must have been a vast improvement over queuing and then working your way through ten locks! The restoration trust is now trying to raise the funds to restore the Foxton inclined plane.
