Instamatic Agfacolour, ain't it blue! The souvenir hunters have already had a go at the numbers off the first of class Hymek at Old Oak Common. This was the day I had my mother's Instamatic and purchased my first 'decent' camera, a Yashica GTN Rangefinder, from a shop off Trafalgar Square. Somewhere there's a black and white neg of this same view!

On garbage trucks there is more than one thing which requires motion..... how do you utilise the 1 or 2 oil flows from the pump across multiple functions? A valve block! The pump is the driving force of the oil, but you also need to control the direction and speed of the oil which is exactly what a valve does. You might find valves sitting side by side in a single group on some trucks or valves could be separated in 2, 3 or 4 areas of a garbage truck, that just depends on the vehicle type and who builds it. Generally a valve does a number of things with oil once it is delivered from the pump; either blocks it off completely or routes it to 1 of 2 functions of an actuator, regulates the flow pressure and controls the velocity. Exactly what the valve does depends on what it is set to do and what signal it receives from an operator perhaps at the push of a button. Exactly how a valve is operated can vary to, whether it be manually with a lever, by a blast of compressed air or electrically via a solenoid. Shown in the picture is the central hydraulic station for an MJE GenV side loader. Quite visible on the left is your large hydraulic oil tank or reservoir, the starting point of the hydraulic circuit, where oil is sucked out by the pump through the black hose running from the bottom. Upon passing through the pumps, oil is routed back to this location on the truck via the two silver pipes above the black suck-out hose. One pipe feeds the lower primary valve manifold and the other feeds the upper paddle valve manifold. Directly above where these pipes fit onto each block, there is a black and blue hose running over the top which take excess or unused oil back to the reservoir to restart the hydraulic circuit. The oil accepted by the valves is sent into the thinner pipes and hoses running off the manifold which shoot oil to various actuators all over the truck, such as the slide cylinder seen sitting underneath everything. On the lower manifold, left to right you have the valves for the slide beam, lifter swing, grabber, body and tailgate. On the upper manifold you have a valve for each of the two paddle cylinders which work in tandem all throughout the packing cycles. Each valve on this truck has a closed neutral position and two open positions which cause an actuator to remain stationary, extend or retract. Atop each valve is a black coil pack which acts on the valve spool depending on electrical signal supplied from the operating system, causing full speed movement, restricted movement or nothing at all.

One of my favourite night shots - Western Class 52 no.1055 Western Advocate at Newton Abbot one July evening with the 2115 Bristol-Plymouth. With fairly relaxed timings, there was plenty of time to take a long exposure and you just can see the parcels being offloaded at the far end of the platform. Ref SL229
Western diesel hydraulics at The Legends of the Great Western open day at Old Oak Common Depot on 2nd September 2017.

1959 Ford Fairlane 500/Galaxie/Galaxy Skyliner, fantastic piece of electrical engineering for its time and no hydraulics anywhere in the whole 18 feet of the thing. Queanbeyan, New South Wales, Australia - Big 3 Car Show. Fairly confident it is a '59, but ....?
It is a matter of lasting regret to me that I never photographed any Warship-class diesel-hydraulics except in the scrapyard. I remember them well enough and they were endemic during my youth. A definite early memory of a Warship dates from Thursday 2nd August 1962 when an all-maroon example carried me, my sister and parents up from Bristol on my first-ever visit to London. One of my great never-taken photographs occurred five years or so later when, at my first job, I was delivering to a customer whose offices were alongside the lines out of Temple Meads Station. The line was up on brick arches, but the first floor of the building was at rail level. As I came up the stairs and turned into the corridor at the top, I looked out through the Crittal windows to see a superb Warship standing bang opposite the building at just the right distance for the camera. It was early on a brilliant sunny day and the slight buckling and distortion of the body panels sent back gleaming reflections. The locomotive was in maroon with all-yellow ends. It wasn't until some time in 1972 that I heard the diesel-hydraulic types were to be scrapped. Instantly ...for my temperament is so constituted... they were invested with hopeless, morbid nostalgia, deliciously pleasurable. But the Warships were already gone. The same thing had happened with steam. At least there was still time for the "Westerns". The shell of D824 HIGHFLYER was still in the scrapyard adjoining Swindon Works on Saturday 22nd March 1975.
One very crucial aspect of engineering on garbage trucks is hydraulics, a topic I find to be fucking awesome and interesting. Without hydraulics there is no motion to the compactors and lifting systems and there is no force available to apply against loads. Pressurised hydraulic oil is delivered to various actuators on a garbage truck which gets all the working components moving with power behind them. The driving force behind the hydraulic fluid is the pump, which is energised by a rotating shaft running off the transmission, which receives power from the truck engine. In the photo we’re looking beneath the chassis of a Superior Pak Dennis side loader, showing the transmission to the left, the pump on the right and the spinning driveshaft which connects them, known as the PTO (power take-off). If the PTO is rotating, power is being transmitted from the engine to the pump, which engages the hydraulic system. Note this particular truck features dual pumps, which is often found on side loaders due to the high demand for hydraulic speed/power to operate multiple functions at once. As seen each pump has a thick intake hose feeding oil from the reservoir and above the pumps is another pair of hoses which inject pressurised oil into the valve system. The pumps are damn strong pieces of machinery, working fast continuously under intense heat and pressure. Just imagine the constant driving power of a diesel engine on one end of the pump, forcing it to push a compactor against 10t of rubbish on the other end.
Using hydraulics, Graham Construction pushed the Peace Bridge across the Bow River using the temporatory bridge struction (rail system). Over the next few days the bridge will be moved sideways and lowered into its pernament location. Work will continue to install the pedestrian / cyclist deck, handrails, lighting / security system and removal of the temporatory bridge struction. The $25-million bridge, which has been controversal for numerous delays and its high price is located just west of Prince's Island Park.

The Port of Workington's 388hp Hunslet 0-6-0 diesel hydraulics (Works Nos.8976 and 8977 built in 1979) outside the two-road locomotive shed in 2011. Although the locos currently only see occasional use with the demise of the Corus Rail traffic from the Moss Bay works and the condemnation and subsequent demolition of the Derwent River bridge as a result of the tragic floods of November 2009, they are maintained in excellent order as part of the Port of Workington's key assets. All berths at the Port are rail-served and it is to be hoped that the locos will continue to see use well into the future. The Port works closely with Direct Rail Services and the Sellafield nuclear reprocessing establishment for specialist shipments.

The last operational day on the Longmoor Military Railway, near Bordon in Hampshire, saw 0-8-0 diesel-hydraulic Army 610 'General Lord Robertson' (Sentinel 10143 built in 1963) standing by the refuelling point as standby locomotive as 0-4-0 diesel-hydraulic 'Army 412' built by the North British Railway Co. (works No.27647 in 1959) crosses the bridge heading for Liss on a track proving run prior to the ceremonial services later that day, on 31st October 1969. Two young off-duty soldiers watch the passage of the North British diesel and single brake van crossing the bridge spanning the throat of the loco shed and yard at Longmoor Camp.

I posted a shot of this taken a few seconds earlier back in 2012. Looking at some 'unposted' images I though this worthy of adding, in fact, I'm a sucker for 'heat haze' off diesel locos and this stood out!
Rijksmonument Waterloopbos is a beautiful and interesting forest in Noordoostpolder of the Netherlands in which the former Waterloopkundig Laboratorium (WL) (1951-1996) was established. Since 2016 this site is a national monument for the period after WOII.
The Waterloopkundig Laboratorium (the official name of the Delft Hydraulics laboratory) was established for hydraulic research in the Netherlands. It had two laboratories at its disposal, viz. the laboratory at Delft and after WWII the laboratory in Noordoostpolder. In the beginning the laboratory in Noordoostpolder was an open-air laboratory. Because of its low-lying situation, water could be guided into and out of small-scale models without pumps. The aim of the studies may either have been a hydraulic design, calibration or improvement of structures or testing of new ideas. The close cooperation between hydraulic structure designers and the researchers of the laboratory allowed the completion of complex infrastructural works like the Deltaworks, as well as large scale international projects.
Through the years, the Waterloopbos has lost its original function. Fortunately, the forest was preserved and is now being managed by Natuurmonumenten (the Dutch Nature Preservation Society). In 2016, the forest was even put on the National Monuments List. The remains of the hydraulic models are still present. Mosses, plants and trees are slowly covering over the sites that were once so valuable. You can hear water flow everywhere and special plants and animals can be found along the river banks. In fall, there are thousands of mushrooms. These elements all serve to give the Waterloopbos its fairytale ambiance.
The famous ‘Delta Flume’ has been transformed. The artists Ronald Rietveld and Erick de Lyon cut huge concrete panels of different widths from the 240 meter long Delta Flume, turning them 90 degrees. The result is a magical experience in a labyrinthine environment. Stand amazed at the way light and dark interact and enjoy the beautiful views of the surrounding nature. Deltawerk// is an ode to the past and the great engineering work that was done here.
Despite the grotty weather at lunchtime today, I popped out of the office for a while, and came across a mechanical digger parked by the side of the road. Managed to get a couple of shots of some of the hydraulic system, and the greasy joints, shortly before the heavens opened...
