on a 2 deg. curve, up to about 3/4 in.
on a 12 deg. curve.
This widening of the gauge should begin on the tangent, back of the
P.C., the full amount of excess over true gauge being reached by the
time the P.C. is reached and continue all the way around the curve,
running from the P.T. in the same manner as back of the P.C.
The spikes should always be driven home straight and at right angles
with the face of the ties. When the foreman in charge of the
track-laying work sees a spiker, when the spike is nearly home, strike
the spike head laterally, which is done to make it lie snugly to the
rail, he should at once check such imperfect work and put the man who
does it at other work. The foreman in charge of gang of spikers should
be experienced in this branch of the work, and by weeding out
imperfect workers, can soon get together a first-rate gang of spikers.
But no trouble will be experienced from carelessly driven spikes, if
the tie has the spike holes bored into it, before laying. This is
considered good practice, but rather expensive.
[Illustration]
For boring the holes quickly and accurately, a proper template should
be made, by which the ties are marked for the borers, who should be
provided with boring machines, by the use of which a hole, square with
the face of the tie is bored.
