 Several more short extensions to the tramway network followed, but the line to Craig Pier was closed on 1 June 1919, as it was not profitable.The Corporation continued to expand the fleet, adding four top-covered cars in 1916, 14 in 1920/21, nine totally enclosed cars between 1923 and 1925, and ten totally enclosed cars with wider bodies for the Lochee route in 1930.They also started to run motor buses in 1922, which gradually replaced some of the trams, with the Constitution Road route being the first to be replaced by buses on 26 February 1928.
