CHAPTER III - Workshops and station machinery Water tanks and water cranes: 1 (a) Minimum height above rail level for discharge orifice of 3660mm water crane (b) Distance from centre of track to face of tank house less than 60 metres beyond the end of a passenger platform. (i) Minimum 7165mm (ii) Recommended 11890mm Note: (a) Item 1(b) need not be observed in the case of small subsidiary or relay tanks which can easily be removed back to provide room for an extension of the yard. (b) Item 1(b)(i) allows for the extension of the platform and item 1(b) (ii) allows for the laying of an additional track and extending of the platform in future. (c) Minimum height for bottom of tank above rail level at water column: (i) For watering engines 7620mm (ii) For washing engines 12190mm (d) Minimum total tank capacity at any station 56.5 cum or 56825 litres (e) Minimum internal diameter for piping from tank to water crane 203mm Workshops and running sheds: 2 Minimum distance from centre to centre of tracks (i) For existing works 4570mm (ii) For new works or alterations to existing works (a) In workshops 4570mm (b) In running sheds 5260mm Note: Where there is a structure between tracks, the distance of centre to centre of tracks is to be increased by the amount of the width of the structure like O.H.E. post etc. 3 Minimum clear distance from centre of track to any isolated structure such as a pillar in: (i) Workshops (a) For existing works 2285mm (b) For new works or alterations to existing works 2360mm 21  (ii) Running sheds 2515mm 4 Minimum clear distance, for a height of 1830 mm above rail level, from centre of track to any continuous structure in (i) Workshops 2745mm (ii) Running sheds 3275mm Note: For standard ‘C’ Railways, minimum horizontal distance for a height of 1830mm above rail level on either side of centre of track to any continuous structure in running sheds shall be 2745mm. 5 Minimum height above rail level to overhead tie bars, girders etc. in workshops and running sheds: (i) Where electric traction is not likely to be used 5030mm (ii) Where electric traction is likely to be used 6250mm 6 Minimum height above rail level of doorways for a width of 1370mm on either side of centre of track in both workshops and running sheds: (i) Where electric traction is not likely to be used 4875mm (ii) Where electric traction is likely to be used 6250mm Ashpits etc.: 7 Average depth for ashpits in station yards, pits in running sheds and 760mm carriage examination pits. Note: Siting of Ashpits on run through lines, should, if possible, be avoided. 22
