Modern Traction Engines
brought the average distance travelled up to 205 miles
per week.
As an instance of what may be done with traction
engines, when intelligently worked, reference may be
made to the experience of the Cliffe Hill Granite Company,
Markfield, Leicester, where two S-horse traction
engines have been regularly worked for several years.
The quarry is situated about three miles from the railway
siding, and each of the engines makes about five
trips per day, hauling an average load of about 13 tons

per trip in two waggons. By this means about 40,000
tons per year are hauled out by the two engines, in
addition to a large quantity of coal and other inward
traffic brought home from the station. Except that the
gradients, which are not very steep in any case, are
generally in favour of the load, this may be taken as a
fair average result, only it must be borne in mind that
some trouble is taken to see that the engines are never
stopped, either from snow or other obstacles. In winter
when there is snow on the ground it is immediately
