7 square
feet; total, 1,069. The boiler pressure is 140 lb., and the tractive force
per lb. of steam in the cylinder 102 lb. The weight in full working order
is, on the bogie wheels, 15 tons 10 cwt.; driving wheels, 13 tons 10 cwt.;
trailing wheels, 13 tons; total, 42 tons.

Mr. Worsdell has lately designed for the Great Eastern Railway a fine type
of coupled express engine, which deserves mention. It has inside
cylinders 18 in. diameter and 24 in. stroke, with coupled wheels 7 ft.
diameter and leading wheels 4 ft. diameter, the latter being fitted with a
radial axle on a somewhat similar plan to that previously described as
adopted by Mr. Webb for the new North-Western engines; the frames are
single, with inside bearings to all the wheels, and Joy's valve gear is
used. The boiler pressure is 140 lb., and the tractive power per lb. of
mean cylinder pressure 92 lb. The total wheel base is 17 ft. 6 in. The
boiler, which is fed by two injectors, is of steel, 11 ft. 5 in. long and
4 ft. 2 in. diameter. The grate area is 17.3 square feet, and the heating
surface is, in the tubes, 1,083; fire-box, 117; total, 1,200 sq. ft. The
weight in working order is, on the leading wheels, 12 tons 19 cwt.;
driving wheels, 15 tons; trailing wheels, 13 tons 4 cwt.; total, 41 tons 3
cwt. These engines burn 27 lb. of coal per train mile with trains
averaging thirteen coaches. It has been seen that the Cheshire lines
express between Liverpool and Manchester is one of the fastest in England,
and the Manchester, Sheffield, and Lincolnshire Railway Company, who works
the trains, has just introduced a new class of engine specially for this
and other express trains on the line. The cylinders are outside, 171/2 in.
diameter and 26 in. stroke, with single driving wheels 7 ft. 5 in.
diameter, the leading and trailing wheels being 3 ft. 8 in. diameter. The
total wheel base is 15 ft. 9 in., and the frames are double, giving
outside bearings to the leading and trailing axles, and inside bearings to
the driving axle. The boiler is 11 ft. 6 in. long and 3 ft. 11 in.
diameter, and the grate area is 17 square feet. The heating surface is in
the tubes 1,057 square feet; fire-box, 87 square feet; total, 1,144 square
feet. The tractive force per pound of mean cylinder pressure is 88.4 lb.
The weight in full working order is, on the leading wheels, 11 tons 3
cwt.; driving wheels, 17 tons 11 cwt.; trailing wheels, 11 tons 18 cwt.;
total, 40 tons 12 cwt. This engin
