What's on the Inside (of those water tanks) Part 2

Some more water tank interior shots.

Binnaway Loco - note identical bracing to that at Binalong

The roof at Canowindra - why the roof? Well no definitive reason
but dust or birds could be the reason.

Note the flat bar bracing

Crooble - note the angle used for the bracing - a much
later style - this tank was constructed in 1931

Something different - the ground level tank at Darnick  - these
were used as emergency tanks and to supply the village.

The Main North K Sets

Taken some time ago on 17 March 2003, two car K Set, K3
arrives at Morrisset after its all stations run from Newcastle.

 

On mornings when I bounce!!!! out of bed and manage to get the 6:23am train from Thornleigh I sometimes see a northbound two car K set canter through Thornleigh at 06:15. This led me to an investigation of the 2 car K sets on the Main North and how they operate resulting in the diagram below. The technical name of this is the flip-flop.

My initial thought was that the train I was seeing was a set returning north after servicing at Maintrain or Flemo - how wrong could I be.

It is actually a service that comes down (Up) from Gosford at 03:45 in the morning and then forms a service from Central to Newcastle that stops at all stations from Berowra onwards and takes six minutes short of three hours for the trip.

I established that in total there are four sets and they stable at either Gosford or Hornsby overnight. Each set visits the Hornsby Maintenance Centre every two to three days depending on which roster it is on.

An interesting part of the rostering of these sets is the Wednesday and Friday’s only empty runs from Newcastle to Morisset and return to Newcastle. Apparently these are to keep Newcastle drivers qualified on the K sets. Most of the Newcastle drivers run the Endeavours to Maitland and beyond and with only a few rosters available for the shuttles to Morisset they can go quite some time without a drive of the K sets – the down and back empty run is used to avoid the drivers running out their qualification.

Another interesting part of the roster is that most of the Morisset trains have to run in to the Up Refuge at Morisset to clear the Up Main for a following interurban - they spend 5 minutes in the refuge and come back to the Up platform before departing for the trip back to Newcastle.

A third point is that the movement from the Up Main to the Up Refuge and the Up Main to the Down Main (when the train departs back to Newcastle) are signalled by lower quadrant shunt signals - the only location left in NSW where this occurs many times a day.

The Northern K Set Flip-Flop

What’s on the inside (of those water tanks)

Many moons ago (1993 to be precise) I was exploring the Stockinbingal to Parkes line and came across the station at Milvale. Now, by the time I arrived there was not much left as the station had closed as a crossing loop on 30 Sept 1986 and all of the station buildings had been demolished. There was though the water tank and in the scrub was the remains of the lever frame. The discovery of the water tank has led me on a journey that has continued to this day – the history of the watering facilities of the railways of New South Wales.

Now on first impressions the water tanks are a box-shaped structure and a stand (in the case of Milvale made of steel), but the tanks are just one part of the watering infrastructure – there being pump houses, excavated tanks, conditioning plants, storage tanks and water columns.

The journey started with the photographing of the many (there are 83) surviving tanks and it was not until I climbed up the wheat silo at Milvale and took a photo (below) that the insides of these tanks opened a whole new area of research.

Now in regards to climbing these ladders – it’s dangerous and you are usually in the middle of no where – so if you fall off – you are stuffed. In my mis-spent youth I have climbed some of these tanks when I have been by myself – I don’t recommend this. In fact it is more than likely illegal anyway.

There is a plethora of bracing on the insides of these tanks, the style depending on when the tank was constructed – as with everything the NSWR built, the later it was built, the more simpler the design and construction materials.

Milvale

The tank at Milvale was constructed with the line and opened for use in August 1916 – with no watering facilities at Stockinbingal every train stopped for water. The 40,000 gallon tank is the standard design for the time and one of three 40,000 gallon tanks on the line - the other two being at Quandialla and Wirrinya – Quandialla is virtually identical to Milvale. The tank was fitted with a 8 inch swinging jib and it also supplied a 9 inch water column located between the main and the loop at the down end of the platform.

Note the outlet valve for the swinging jib and the different style
of bracing (from the base to the walls) for the upper and lower tiers
of panels and the additional three layers of bracing in the corners.

Binalong

There are two tanks at Binalong and I will concentrate on the tank on the top of the cutting. This tank is somewhat unusual in that it is a single tier 40,000 gallon tank. The bracing of this tank is identical to that of the first tier at Milvale and research has found this to be the standard design used for a long period.

Bullenbung Creek

Bullenbung Creek, the only watering facility on the Kywong Line, is an earlier style tank that was relocated from another location when the line opened in 1928 – while the tank is a single tier 20,000 gallon type, the panels of the tank and the bracing are of an older style. This was also one of the few tanks provided with an American type lifting jib (more of them in a other blog entry in the future).

Yannergee 

Yannergee is located approximately halfway between Werris Creek and Binnaway and was one of two locations on the line to have watering facilities – the other being Caroona although it was removed in 1941. As a result of it being the only facility on the line since then all trains stopped to take water at Yannergee. The tank was initially a 20,000 gallon tank but it’s capacity was doubled in March 1941 – it is possible that some of the required parts came from Caroona. When the capacity was increased the bracing of the first tier was renewed in the current style. The overall bracing of this tank is the one of the final variants of bracing used in NSW.

Note that the only bracing of the top tier is across the corners.

A more detailed view of the bracing at Yannergee.
Note the the bracing is made of angle whereas earlier
examples (Binalong and Milvale) above are of a flat bar type.

 Some more examples will follow in due course.
