OV 9 Mobil Tank Wagon


Over the last few months I have been building tank wagons. Some of the tank wagons on the layout date back to the mid 1970’s, they are on their third set of bogies and my modelling standards have improved a little over time.

Thus a program to replace a few of these wagons has started. In this batch I did six wagons. One of the tank wagons in this batch is OV 9.

A couple of weekends ago I entered the wagon in the NMRA Regional Convention Modelling Contest. The judging is carried out with 125 points on offer. The model scored 113, I was marked down for not adding some detail. I build rollingstock to run on the layout, if you cannot see it standing on the track I don’t add it. But, it is something for me to think about in the future. The items missing are not hard to do and on tank wagons could add more to the model. 

OV 9 Homestead 1969. The wagon was taken off a train due to a hot box.

 One plan covers all wagons within the class.
This wagon I used Evergreen styrene for the underframe. Some of the other wagons in the batch I used "North Yard" brass strips.
 
The model was painted with Tru-color TCP-010 Black.
Decal were made by Ted Freeman in Toowoomba. Email teditor@bigpond.com
 
 The model was weathered with Vallejo  Model Color acrylic paint.
 
This coming weekend (Saturday14th of October), I will be doing a clinic on Tank Wagons at the Modelling the Railways of Queensland Convention. How the wagons were constructed and the missing parts will be disclosed.
 
The other wagons will make it onto the blog after the Convention.

Mutton Bird nesting Season



Over the last few weeks, Westagte has hosted a number of meetings and visitors. During the NMRA Divisional 1 meeting I was informed by the CEO of Cassino (who will remain nameless) that a mutton bird had landed in the Jacaranda tree on Smith’s farm and was making a nest. 

The photo below is what I found ????
 

Well done Craig.

WHE Wheat Wagon



Landsborough (General Traffic 1973)
WHX were constructed by Commonwealth Engineering Salisbury between April 1959 and November 1960. All up 300 wagons were built (31308 – 31607) to supplement the 200 WH class wagons to carry bulk wheat. At first they were mainly used to carry bulk wheat from the Darling Downs to the State Wheat Board terminal at Pinkenba. Wagons were unloaded on a tippler. Wagons also conveyed wheat to various flour mills on the Downs and Brisbane.  
The wagon floor footprint was 12 185 mm by 2 440 mm, and the sides were 1220 mm high, 140 mm higher than the earlier WH wagons, given them 36.25 m³ cubic capacity. The wagons had a nominal tare 13. 4 t and could carry 30.2 t on “S” (20 TAL), “A” (15 TAL) and on some “B” class lines, or 26.1 t on all lines (10 TAL). Supplement to the Working Time Table allowed them to carry full loads on most branch lines on the Darling Downs.

The wagons were fitted with “Premier” (later known as D2) drawgear, drawhooks with fixed screw couplings at each end. Bradford Kendall cast steel QR 9 Bogies were fitted to the wagon, 850mm (2’ 9½”) wheels running on SKF rolling bearings. A chain/ratch hand brake secured the wagon from movement when not in a train. I would think this was the first wagons to be fitted with this type of hand brake. Wheel hand brakes were on BLC wagons and various tank wagons, but they were the screw type. The chain/ratch hand brake is still being fitted to wagons today.
A single tarpaulin was used to protect the load from the weather. Seven supports along the wagon kept the tarp off the load and provide fall to let water to run off during wet weather. The supports each side of the doors pivoted to allow a ridge bar to telescope inside each other across the doors. Early photos of the wagons suggest this may of been added later, they are standard on wagons in 1969. The tarps were 48 feet x 14 feet (13 700 mm x 4 000mm), originally they were green in colour. With the introduction of P.V.C traps around 1972, the colour changed to yellow. During the trial period of P.V.C traps for a short period in the early 70’s, some were orange. Prior to 1962 grain traps were numbered by the year and the wagon number. I.e. Q ^ R (first line) 62 (second Line) 25561 (Third line).  After 1962 the number was the year of manufacture and the number made for that year i.e. 82-11. In later years the QR was replaces with the logo.   

The wagon class was changed to WHE in 1964/5, the new ROA coding being introduced at the time put a new meaning to the letter, the “X” on the end of a wagon class identify the wagon are being able to be bogie exchanged. The new “E” class indicated 11/12 ton axle load vehicle. 
On trains, WHE wagons having the stronger drawgear (D2) than the WH class wagons (D3), they were generally at the front of the train to obtain the maximum load for the haling locomotive.

The wagons were also used to carry barley to Whinstanes when in season. The wagons were unloaded by a back hoe. A “U” shape scoop with sides that could be moved out was fitted to the rear arm. The barley was pulled towards the open door into a hopper fitted with an auger to load trucks. Previously I referred to the pivoting trap supports, by folding back the supports and removing the ridge pole, the scoop could reach to the far side of the wagon. Grain in the corners was shovelled out to within the reach of the scoop. 
General Appendix states the wagons should remain covered at all times, loaded or empty. It also indicates particular attention must be paid to avoiding tarpaulins sagging between supports.  

A full load for a 90 ton DEL (1450, 1460, 1502, 1270, 1300 class etc.) from Toowoomba to Brisbane varied a little over the years. In 1976 it was 1120 tons for D 1 & D2 rollingstock, 880 tons for D3 and 630 for D4 wagons. WH wagons, on QR 5 bogies had a gross of 36 tons and were D3 class drawgear. That about 24 wagons and a van for a full load. In the early 1970’s these wagon were fitted QR 17 bogies and reclassed WHA, a fully loaded wagon had a gross of 39 tons, that’s about 22 wagons with a van for a full load. WHE wagons fitted with D 2 drawgear fully loaded were 44 tons, that’s about 25 wagons with a van for a full load. Most trains had a mix of classes, WHE wagons would be marshalled on the front to achieve the maximum load for the hauling locomotive. Thus the number of wagons on a train would alter  from train to train. The leading 240 tons (6 wagons) must be WHE wagons.

Between Toowoomba and Brisbane it was a common sight to see a full train load of grain wagons. The depots on the Downs didn’t have a huge loading capacity, many in 2002 still had equipment that could handle about 150/200 tons per hour. Grain sets were spill up over two or three locations. Turnaround time was around 2 to 3 days. Some photos suggest small numbers of wagons were conveyed on local goods trains to Toowoomba.  A few years back there were 13 sets of grain wagons with up to five (5) loaded trains a day coming to Brisbane when a ship was in port.      

 In 1969 all goods/freight wagons were painted grey. After mid 1970, same has QR logos added to the side.   



Around 1972, automatic coupling with transition links were progressive fitted to the wagons, converted wagons were classes WHET, D 1 drawgear.  Fitting of the stronger drawgear paved the way to multi – unit operations resulting in bigger trains. With the introduction of QGX wagons with bottom discharge, commenced the start of WHE wagon being used for other traffic, wagons allocated to general traffic were classes WHES/WHETS. A number of wagons were allocated to Fertilizer traffic, WHEF/WHEFT.

Around the mid to late 1980’s grain export moved to Fisherman Islands, only bottom discharge wagons could be used.

A number of open grain wagons were allocated to Coal & Minerals, WHETC was given to these wagons. WHEU identified Rollingstock Maintenance allocated wagons (Traction Motors 31607/31557).
30 WHE wagons used in the Thalanga (ND) Traffic (91) until the arrival of the PHY wagons.

In the late 1980’s, the underframes of WHE wagons were being using to replace older wagons in other traffic.

WSC 31330 Trail Sheep wagon fitted with WAGR Containers, became PCS Sheep wagons. Carry 208 head of sheep.


 
Containers were removed (95) reclasses PCEX .

PWH Pineapple Wagons, end extended to carry CQ bin three high.
 

WHW Wheels wagons. (Wheels between Workshops and Depots)

 
WHEW Winch wagons for recovery rail.

PW Loco Bogies.

WCC Bulk Cement Wagons (5 x 5 ton bins).

IBJX Plough Wagons

 
IBXR Ballast Cleaning Machine. (Tank & Generator)

Tank Wagon underframes, various classes. ARHS Sunshine Express March 1993 shows 72 tank wagons were fitted with new underframes, 22 were from WHE wagons.
 
VR Bitumen wagons VTBY 518 & 523 mounted on WHE wagon frames to become Shell OBET 43941 & 43942.  (90).

WHED Bogie Frames. (Jilalan – Rockhampton)

WSE Water Wagons, later Molasses Wagons. (Some WSE wagons were BLC underframes).
 

A couple of WHE wagons were used as cover wagons for Kuranda cars when conveyed between Cairns and Townsville.

Models.

The wagons are P.G.C Scale Models. The kit is a one piece body,  2 hand brake wheels with wire, 4 ladders for side steps, Bogies (disc wheels), Etch brass tarpaulin supports, brake cylinder, 4 buffers, and decals.



 
Assembly is straight forward, add detail items to the body, paint, add decals, bogies, couplings and weather.  For the layout these wagons are to be grain wagons operating in the sixties. Some extra brake gear was added. Kadee # 115 coupler boxes fitted with 158 scale whisker couplers were used.  Ridge poles were added to the tarpaulin supports across the door. The wagons were painted with True-color Weathered Black. For my money, black wagons had spoked wheels. H0 Steam Era bogies were modified to take Steam Era 9.5 mm 12 mm wheelsets. Some lead sheet was added to the floor to bring the wagons up to 55 grams. The tarpaulin was made from thin plastic sheet off a large medical wound bandage, which was blue in colour.  The plastic sheet was cut to size as shown above and fixed to the wagon with super glue. The trap was painted green using Humbol #2 with # 22 white added. The amount of white varied between each wagon. Home made decals trap number were added thanks to Ken Edge-Williams. The completed wagon was sprayed with gloss coat, then with dullcote. Weathering was completed using Vallejo.

Hey Boss


Hey Boss,  I found 2 slots for that 40’ container of steel. All good to go tonight now, you don’t need that extra wagon.

 


If you were the Boss, what would you say ???????

Minu Multies / Weathering


Mini Multies / Weathering.

After the Brisbane electrification, the 1720 spread their winds state wide and took on new  roles.

Things were changing quickly in the bush too. One of the first application of the mini multies was the AM Sunlander (237/236) from Brisbane and the “Queenslander”. Originally multi 93t DEL’s were rostered on these trains, yes a faster time table was set but the trains were only a few cars over the single loco load. Passenger comfort was effected greatly. The answer was in the 1720’s, a 93t and a 63t locos fit the bill nicely. This could be the reason that 1723 got the bi-centennial livery, 2401 and 1723 in their bi-centennial colours first outing together was on the “Queenslander”. In the SED around Brisbane this hook up became known as a mini multie.
 

Also on the freight side, wagons were being fitted with better braking systems and the length of trains increased for 90 units (450 metres) to 650 metres. Once again two 93t locomotives was a waste of power on the longer trains. On general freight trains just about every wagons has a different weight/mass, full single engines loads were not that far short of the full length, thus a 93t loco was being added for a couple hundred extra tonnes. Once again the 1720 loco was the answer. With the longer trains being pushed around shunting yards, an engine with a bit of grunt was required, you guested it, and the 1720’s filled the bill.      

Early 2000’s, third party operators arrived on the network and trains were allocated paths, trains running late and falling out of their paths became a sick train and lost it run. Plus depots were get fewer and far between, if an engine fell over, the nearest loco for assistance could be hundreds of K’s and many hours away. Late trains cause a lot of issues for the operator and customer. 1720’s filled this insurance role, sometimes the trip can be somewhat a lot slower.

Much the same with Cattle Trains, the extra power is not required all that much, just a hill or two along the route.

Weathering

The two locos in the photos have been weathered using Vallejo acrylic paints. These paints come in 17 ml eyedropper plastic bottle. One or two drops go a long way, dries quickly and cleans up in water. Shop around, the war game suppler sell them for about $ 4.50, generally, at hobby shops they my cost $ 5.00/5.50. The range of colour available is huge.   

   

First I washed the body by brushing it with windshield washer cleaner. Currently I using an ammonia free Armorall Glass Cleaner I purchased from Super Cheap for around $ 10.00. (Sometimes it cheaper with weekend specials).    

1.    A Grey wash was applied for a faded appearance (Model Color # 70.989 Sky Grey), a couple of drops in about a dessert spoon of windshield washer cleaner.

2.    To highlight the various panel doors etc. a Black Wash was applied. (Model Color # 70.862 Black/Grey), a couple of drops in about a dessert spoon of windshield washer cleaner.

3.    Vent and grills were picked out with Model Color # 70.862 Black/Grey. A couple of drops in an artist tray, add a couple of drops of windshield washer cleaner.

4.    The same was used on the bogies.

5.    Top of the footplate was given a khaki 50/50 wash (Model Color # 70.088)

6.    From there on, a photo/s could be very usefully, when weathering, not two are the same, era plays a big part, service location, last time the loco was painted / washed / steam cleaned, fuel/oil spills, markings etc. all come into play.   

7.    Brake blocks on these loco were painted “Rust’ colour, but various period with fibrous blocks I recall them in blue, yellow, purple, sometimes test blocks can be a different colour again.   

8.    The ends of the fuel tank and sand boxes can have undercoat showing through, springs can have a bit of rust at times. The colours I been trying on the bogies have been Rust (Model Air # 71.069, Model Air is said to be airbrush ready whereas Model Color is thicker), Earth - Game Air # 72.762, Dirt - Model Air # 71.133, Burnt Umber - Model Color # 70.941.

9.    Fuel spills on the tank, footplate and oil on the panel sides I use what black I have open, I still have some Floquil “Engine Black” that I’m using up.

10. On some, the cab roof can have a bit rust, Earth - Model Air # 72.762

11. To finish the model I spray 50/50 paint/thinners (Armorall Glass Cleaner),

 Dirt – Model Air # 71.133, Earth- Game Air 72.762, and Dust- AK Interactive AK 723. Start with the darker colours and work down to the lighter colours. On the top a fine spray of Model Color # 70.862 Black/Grey, may be a bit more around the exhaust stack.






Trust you fine it helpfully, early days and more experimenting (fun) still to be done. The paints are awesome for painting figures too.
