What are water troughs for?

Water troughs enabled a locomotive to take water whilst on the move.  Although designed and installed for steam locomotives, they were also used by diesel locomotives to replenish their steam heating boilers.  Troughs were laid between the rails and were typically a little over a quarter mile long; a scoop on the locomotive was lowered into them where the train's movement caused sufficient pressure to force the water up and into the locomotive's tank.  The signs to inform train crew of the trough location can be found on this Railsigns page.

Water trough use

Most railways installed troughs at just a few key sites to allow for non-stop running of their prime expresses.  As a result, they built large tenders and had to drag them (and a huge mass of water) around because of the sections of their networks which did not have troughs.

It will be seen that a large proportion of trough locations are on L&NWR lines. This railway used troughs differently from most other railways.  The L&NWR sited them at roughly 30 mile intervals on its main lines, allowing it to have quite small tenders for its engines.  Once most of the troughs were in place it reduced the capacity of new tenders from 2000 gallons to 1500 gallons.  Even in the Company's later days, with large engines such as 'Claughtons', it never built tenders with a capacity of over 3000 gallons.

Constraints to using water troughs

The troughs naturally had to be on dead level track.  The ideal speed at which to collect water was around 45mph; railway regulations limited trains to 70mph (75mph on the West Coast Main Line) whilst passing over troughs whether or not taking water.

As can be imagined, dropping a scoop at speed into water would waste a good proportion.  This was recognised in official operating regulations, for example in 1951 the Western Region rules had:


Owing to the risk of water entering compartments when engines are taking water whilst passing over water troughs, passengers in the leading vehicles should be warned of the advisability of keeping the windows closed when the troughs are being approached. The responsibility for issuing the warning will rest with: (1) Train Ticket Collectors where employed. (2) Guards where Train Ticket Collectors are not employed. (3) Restaurant Car Conductors when the Restaurant Car is in front of train and conveying passengers.

Very similar text appeared in the 1942 L&NER rules.

Regularly spraying water at high force over the formation could disturb the ballast, so the surrounding sleepers were covered with further sleepers.  This did not help drainage and trough locations were known for 'wet bed' problems where the underlying ground turns to soft mud allowing the track to sink, exacerbating the problem.

The rule book also gave instructions on what to do in winter when ice formed in the troughs, in 1954 reading thus:


1. The Length Ganger will be responsible for keeping ice broken and cleared from the troughs. 2. The Length Ganger must use his discretion when the ice thickens as to when the troughs should be closed, but must not allow the ice to become more than 1/8 in. thick before arranging for the troughs to be closed. If the temperature is so low that the water freezes as quickly as it is cleared the troughs must be closed. 3. If ice collects in the four foot to a depth of 1 in. due to spillage the troughs must be closed. 4. When the Length Ganger finds it necessary to close the troughs as set out in Clause 2, he must advise the nearest Signalman who will notify the District Controller. In turn the District Controller will immediately notify the following: Mechanical and Electrical Engineer's Outdoor Machinery District Mechanical Foreman or Local Mechanical Chargeman and responsible Water Fitter whichever is most convenient. Motive Power Depots. District Motive Power Superintendent. Mechanical & Electrical Engineer's Works Manager. District Engineer. The Length Ganger must also advise his Permanent Way Inspector. 5. When a thaw sets in after prolonged frost the Mechanical and Electrical Engineer's Outdoor Machinery District Mechanical Foreman or Local Mechanical Chargeman or responsible Water Fitter, whichever is most convenient, after consulting with the Ganger, will say when normal taking of water can be resumed. The Ganger will advise the nearest Signalman who must advise the District Controller, and he will notify the Departments listed in Clause 4 that normal working of the trough can be resumed. 6. The District Operating Superintendent or District Traffic Superintendent to notify promptly the Operating Superintendent, who will issue the necessary instructions in regard to the taking of water while the water trough is out of use.

In 1937 the LMS encouraged its crews, if the troughs were frozen, only to make unscheduled stops at Bletchley, Crewe, Leighton Buzzard, Llandudno Junction, Preston, Rugby, Stafford or Tebay (as appropriate).  No doubt the other railways had similar preferences and constraints.

Infrastructure maintenance near troughs could be difficult.  Despite the Southern never having any troughs, the 1960 South Western lines Sectional Appendix cautioned firemen against lowering the scoop at the wrong moment:


Where water troughs are in close proximity to Distant signals or multiple aspect colour light signals special care should be exercised when lowering or raising scoops to ensure that the latter do not come into contact with the A.W.S. ramp.

Similarly, there could be problems with locomotive detritus falling into the troughs affecting maintenance.  A 1932 LMS notice stated:


Complaint is made of difficulty in maintaining the Water in the Locomotive Water Troughs at a proper level through the presence of ashes interfering with the adjustment. Care must be taken by all Enginemen to prevent ashes falling in the Troughs, as far as this can be done, and it is a desirable expedient to close the damper doors when passing over the Water Troughs, whether water is being taken or not.
