RAILWAY CONSTRUCTION. 



railway, the course of such existing railway must be shown on 

 the plan for a distance of 800 yards on each side of the proposed 

 junction. In the case of Bills for constructing subways, the 

 plans and sections must indicate the height and width of such 

 subway, and the nature of the approaches by which it is proposed 

 to afford access to such subway. 



The Book of Reference must contain the names of all owners, 

 lessees, and occupiers of all lands and houses of every parish 

 within the limits of deviation. 



The numbers on the Book of Reference must correspond with 

 the numbers on the plan, and opposite to each number must be 

 entered a brief description of the property, whether field, garden, 

 house, road, railway, or river. It is intended that the plan and 

 Book of Reference together, shall afford ample information to 

 enable all parties interested to ascertain to what extent their 

 property will be affected by the proposed undertaking. 



The section must be drawn to the same horizontal scale as 

 the plan, and to a vertical scale of not less than 100 feet to an 

 inch, and must show the level of the ground, the level of the 

 proposed work, the height of every embankment, the depth of 

 every cutting, and a horizontal datum line which shall be referred 

 to some fixed point, near one of the termini. 



In every section of a railway, the line of railway marked 

 thereon must correspond with the upper surface of the rails. 



Distances on the datum line must be marked in miles and 

 furlongs to correspond with those on the plan ; a vertical measure 

 from the datum line to the line of the railway must be marked 

 in feet and decimals at the commencement and termination of 

 the railway, and at each change of gradient, and the rate of 

 inclination between such vertical measures must also be marked. 



Wherever the line of railway crosses any public carriage 

 road, navigable river, canal, or railway, the height of the railway 

 over, or depth beneath the surface thereof, and the height and 

 span of every arch by which the railway will be carried over the 

 same, must be marked in figures. 



In the case of a public road level crossing, it must be described 

 on the section, and it must also be stated if such level will be 

 unaltered. If any alteration be intended in the level of any 

 canal, public road, or railway which will be crossed by the 

 intended line of railway, the same must be stated on the section 

 and cross-sections to a horizontal scale of not less than 330 feet
