Water troughs on British Railways
TAKING UP WATER from Bushey troughs, nearly sixteen miles from Euston, on the main line of the Western Division.

It was in 1860 that Mr. John Ramsbottom, at that time chief mechanical engineer of the London and North Western Railway, introduced the water trough and pick-

The total length of the troughs varies, but it is usually about 500 yards, the ends gradually tapering out. Towards the end of the troughs the track is graded at 1 in 300, down at the entering end, and up at the leaving end, while the end portions have a gradient of 1 in 192. The rails are parallel to the surface of the bottom of the trough, so that if the fireman does not raise the scoop in time, it comes out of the water automatically.
The operation of picking-
The troughs consist of steel plate bent to the required shape, supplied in lengths and riveted together. They are about

Arrangements have to be made to keep the troughs full of water automatically, and as this must be done fairly rapidly, the water is fed to the troughs at several points, the flow being governed by float valves similar to the domestic ball cock in the cistern. The troughs require frequent cleaning out as small pieces of ballast get washed into them and also leaves and other small pieces of rubbish.
The apparatus required on the engine is quite simple in construction. There is a gun-
Owing to the pressure set up by the water, it is not easy to raise the scoop when the engine is travelling fast, and it may be necessary to raise it before the end of the. trough is reached. This is usually done nowadays by a small cylinder and piston, actuated by steam, compressed air or vacuum. A balance-

The lowest speed for the locomotive at which the water will rise high enough in the delivery pipe to discharge into the tender tank is about 15 to 20 miles per hour, and the higher the speed the more water can be picked up. When a train has two engines drawing it, the leading or pilot engine dips in first, and about half-
In order that readers may be able to look out for these troughs whenever they are travelling, we give below a list of all those on the British railways. They are invariably laid in both the up and the down lines.
