The June AMRM had an article by Peter Jarvis on
Modelling The NSWGR Steam Locomotive Watering Facilities.

Which I thought was very good .But as it says Modelling I think the main point has been missed .In that all the photos shown are of tanks as we would see them and that is from ground level.

BOLIVIA was built as high as possible so that track level would be at eye level and the trains and scenery would be seen as in real life from ground level . With the viewer having to look around structures and scenery to see the trains .And moving around to view them and thus changing the way the layout looks from different angles.
But even still you look down on the layout.Not as bad as some layouts that give you a view as if you where in a plane.But this means that most important part of modelling a water tank is the internals from the top .Which most people wouldn't know about because they have never seen in the top of a tank.

These shots are from Glenreagh and although much deteriorated in condition show the wealth of detail needed.On the part your going to see the most.

This is the water tank on BOLIVIA showing the bracing , inlets and also some algae growth.

Bye the way does any one have internal shots of a parachute tank or the wrought iron circular tanks

This is the under side of Byron Bays tank all I need is the top view.

  1. I agree with you totally Rohan, but how clear would the water be in a tank?

    I would assume it would be so dirty brown that you would not see through it, but I've been wrong before.

  2. Andrew.
    Most water taken from bores ,wells or rivers is relatively clear and was also taken from locations that would be of the best quality available.And with the water stored settling occures over time.
    As the railways had an interest in the suitability of water to be boiled and evaporated they went to a lot of trouble to make sure the water was as clean and soft as possible.As any impurities in the water once heated, decide to coat all surfaces.And this clogs pipes and heat transfer surfaces,reducing the thermal efficences by ever increasing amounts.
    Meaning that heat energy (BTU,S) wont transfer to the water.
    More coal consumed to do the job and increased maintenance means more cost.
    So in answer to the question most tanks would be clear enough to see through to the bottom with no trouble.So yes you will have to detail the inside of the tank.
    As for the softening of water , the Glenreagh tank had a softening unit on the side as did a lot of other locations.Im not sure what method was used.but I dont think it was the same as a conventional softener as used in a house or commercial application from probable the 1960,s.
    Does anyone have any info on railway softening units.
