Plate-layer^ tools cost from £,<^ tO;^2o per set, and a proper selec-
tion depends on the following information : — ^

The extent of railway for which the tools are required ; the amount
of tndfic as indicated by the number of trains per day or the number
of train-miles ; the gauge of the railway, and the width of the ** six-
foot j " the system of permanent-way, describing the section and weight
of the rails, and the mode of fastening and jointing them ; the weight
of the engines ; the climate ; and the kind of workmen employed.
Ramps by which engines and wagons may be replaced on the line
after accidental derailment are now generally used on railways.
They cost from £^2 to J^2i ^^ich and weigh from 80 to ,100 lbs., so
that they may be carried on the engine or in the guard's carriage.

CHAPTER XXIL

RAILWAY EQUIPMENT (CONTINUED). LOCOMOTIVES AND

ROLLING-STOCK.
^t bif eai^ In the design and equipment of a new railway, the Locomotives should
nSbvay 'project. ^^ considered at an early stage of the proceedings ; for if this be not

done, and the railway be laid out, and the gradients, curves, and
permanent-way settled, the locomotive engineer, when his time
comes, will find that he has to carry the traffic under conditions
which he might have improved if he had been consulted earlier.
