Locomotives on Highways. 



modifies the provisions of sub-section (4) of Section 28 of the 

 Highways and Locomotives (Amendment) Act, 1878. 



It provides that a locomotive may be used, the driving wheels 

 of which, instead of being smooth-soled or shod with diagonal 

 cross-bars, are shod with wooden blocks, subject to the condi- 

 tions that the width of each block, measured along the circum- 

 ference of the wheel, shall be not less than 6 in. ; and measured 

 across the circumference of the wheel, shall also be not less than 

 6 in. Provided that if the width prescribed by sub-section (1) 

 or sub-section (2) of Section 28 of the Highways and Loco- 

 motives (Amendment) Act, 1878, for the tire of the driving 

 wheels exceeds 18 in., the width of any block, measured across 

 the circumference of the wheel, shall be not less than the width 

 prescribed by such of the following rules as may be applicable 

 to the circumstances of the case, viz. : — 



If the width of the tire does not exceed 20 in. the width of 

 the block shall be 6^ in. If the width of the tire exceeds 20 in., 

 but does not exceed 22 in., the width of the block shall be 7 in. 

 If the width of the tire exceeds 22 in., but does not exceed 26 in., 

 the width of the block shall be 8 in. If the width of the tire 

 exceeds 26 in., but does not exceed 28 in., the width of the block 

 shall be 8| in. 



The interval between any two blocks, measured along the 

 circumference of the wheel, shall be not more than 2 in. 



The blocks shall be arranged in two or more rows, and so 

 that a straight line drawn through the middle of each block shall 

 pass through the middle of the interval between the blocks of 

 the next row. 



The blocks shall work on efficient springs or other elastic 

 material so as to yield with the pressure of the weight of the 

 locomotive ; but not so that the surface of the wood block shall 

 be at any time level with or depressed below the tire of the wheel. 



No wheel shall be used, any block of which is so worn that 

 any metal rim surrounding the block protrudes beyond the 

 surface of the block.
