In 1887, Robert took his two eldest sons, Robert junior and William, out of school to help him, with Malcolm and Alfred following soon after, and they did much to rationalise the firm’s administration and finances. Undaunted by his earlier experience, McAlpine took on further railway contracts, this time successfully, including the Mallaig Extension Railway and the Glasgow Subway. There was an increasingly wide range of building and civil engineering contracts but the firm was almost brought to its knees again with the construction of the Methil Docks between 1909 and 1913. It was argued that this led to a much more cautious approach to risk on the part of the sons – if not the father.
