The procedures and practices in relation to the buildings and structures on Indian Railways were laid down in the Indian Railways Way and Works Manual of 1967, which was to be revised into three different Manuals viz. P. Way, Bridges and Works. While the P. Way and Bridge Manuals in their revised form were published in 1986 and 1998 respectively, Works Manual is now being published in the completely updated and revised form. With the modifications in the functioning related to works as well as due to introduction of new types of structures, some radical changes were inescapable. The recent shift in emphasis on customer care, passenger amenities, commercial exploitation of railway land and afforestation in the railway premises required provisions in the Works Manual. Also, new methodologies now available have been included in the Manual for the benefit of the civil engineers responsible for the construction and maintenance of railway assets.
