The canal's success kept it going far longer than many of its contemporaries in the face of competition from the railways. When the Grand Union Canal Company took over the running of the Erewash in 1932 it was still a going concern. The canal was nationalised in 1947. By this time the closure of feeder canals resulting in a loss of trade and competition from other forms of transport was making itself felt and the last commercial narrowboat delivered its cargo in 1952. In 1962 the British Transport Commission closed the top section of canal. However, it was kept in water to supply the lower half of the canal and it remained navigable.
