The disposal of non-operational property owned by BRB (Residuary) Ltd. (BRBR) is governed by guidance issued to the company on 26 July 2007 which I outlined in my statement to Parliament on that date. Since 1 April 2007, BRBR have disposed of 13 properties that contain disused rail lines. The disposal of railway property owned by Network Rail is undertaken in accordance with the conditions of their network license. Compliance with these conditions are monitored and enforced by the Office of Rail Regulation.
