Replace the first paragraph of  preamble under the heading “RECOMMENDED DIMENSIONS” by the following

 

The following are some recommended dimensions, which are generally considered good practice, the adoption of which will lead to very desirable uniformity on Indian Railways, but they are not to be treated as standards, a departure from which requires sanction.  The clearances to fixed structures and distance centre of tracks prescribed in item 13 of chapter I, Schedule-I for Tunnels and through Girder bridges should also be adopted for all structures, and not only for Tunnels and through Girder bridges at the time of new construction, or additions/alternations to the existing structures.  If, however, in cases where 3660 mm (12ft.)in.) stock is not expected to be introduced and adoption of these dimensions would, entail heavy expenditure, an administrative reference should be made to the Board individually in each case before execution of the work for adopting less clearances
