Directly Operated Railways Ltd. (DOR) was a holding company set up by the Department for Transport in the United Kingdom in July 2009 to operate rail franchises should it become necessary to bring them into public ownership. From November 2015, its function was taken over by the Department for Transport, who set up DfT OLR Holdings Limited to carry out that function. A partnership of Arup Group, Ernst & Young and SNC-Lavalin Rail & Transit were appointed temporarily to support them in that function.
