16 RAILWAY CONSTRUCTION. 



The same details for each branch, and general summary of 

 total cost. 



Every Railway Bill must be read twice, both in the House 

 of Commons and in the House of Lords. A committee, duly 

 appointed for each House, must report upon it, and if the reports 

 from such committees be favourable, the Bill will be read a 

 third time, and passed. 



When it has passed both Houses, the Bill receives the Royal 

 Assent, and becomes law. 



The minimum scale of four inches to a mile for the plans is 

 so very small that it is rarely, if ever, adopted. It would 

 necessitate enlarged plans of so many portions to show clearly 

 the property or buildings inside the limits of deviation, that in 

 practice it is found expedient to make the plans to a much 

 larger scale. 



Figs. 1 and 2 show a small portion of a Parliamentary plan 

 and section drawn to the minimum scale allowed, with an 

 enlargement of a small part to distinguish the houses clearly. 



Figs. 3 and 4 show a part of the same plan and section drawn 

 to a scale of 400 feet to an inch, a scale which is very frequently 

 adopted, and is sufficiently large to distinguish the buildings 

 and small plots, except in closely populated districts. This scale 

 also gives ample room for reference numbers. 



The Parliamentary plans and sections must be accurate in 

 delineation, levels, and description. All property within the 

 prescribed limits of deviation must be clearly shown, and the 

 numbers and description on the plans and book of reference 

 must be concise and complete, to enable the owners to ascertain 

 to what extent they will be affected. In every place where it is 

 proposed to interfere with any public highway, street, footpath, 

 river or canal, the manner of such proposed alteration must be 

 shown and described on both plan and section. The commence- 

 ment and termination of every tunnel must be correctly indicated, 

 and the length given on both plan and section. An omission of 

 any of the above requirements might prove very detrimental to 

 the scheme, and possibly result in the Bill being thrown out of 

 Parliament for non-compliance with standing orders. 



In carrying out the works the constructors have power to 

 deviate the centre line either to the one side or the other, 

 provided that such deviation will permit of the boundary of the 

 works, or property to be acquired, to come within the limits
