The keys which hold the rail in the chairs are usually of oak and are placed outside the rails; the inside position has also been employed, but has the disadvantage of detracting from the elasticity of the road since the weight of a passing train presses the rails up against a rigid mass of metal instead of against a slightly yielding block of wood.
Pulling the rail back up, she stood beside the tent, helplessly watching Destiny cry until she coughed herself into another retching fit.
At one end of each rail the flange spread out to form a foot which rested on a cross sleeper, being secured to the latter by a spike passing through a central hole, and above this foot the rail was so shaped as to form a socket into which was fitted the end of the next rail.
Sand, driven between the wheel and the rail by a steam jet, used just at starting, increases the adhesion beyond the normal value and enables a larger pressure to be exerted on the piston than would otherwise be possible.
In years long gone it was the rail bed for the line that ran to terminus in Ouray and now a favorite path for bikers.
Long, which are lodged in the channels of the rail, one on each side, and secured with four bolts passing through the web; sometimes, to give additional stiffness, they extend down below the lower table of the rail and are bent round so as to clip it.
Alex was standing on the porch, leaning on the rail and nursing a cup of coffee.
The gear operating the paper roll is driven from the axle of an inde pendent wheel which is let down into contact with the rail when required This wheel serves also to measure the distance travelled.
Purposes: they diminish the wear of the sleeper under the rail by providing a larger bearing surface, and they help to support the spikes and so to keep the gauge.
The difference between the horizontal distance and the distance measured along the rail is so small that it is negligible in all practical calculations.
