Pulse width modulation of the LEDs, swung about on the end of their cable in the Victoria Tunnel.

Like a numpty, I'd left my cable release at home, so was stuck to a 30s max exposure time. Also reckon the camera angle is wrong here, resulting in a bad case of excessive orbage placement in the upper regions.

Changed the tube to blue, and annoyingly, the pot that controls the speed of the fade broke off.

Plant Water Management - nom de code : PWM. C’est une nouvelle façon d’utiliser l'hydroponie pour faire pousser des plantes dans l’espace, avec le très pédagogue Marc et moi-même – qui apparemment manquais de sommeil [emoji blague]. Cette technique n’utilise pas de terre ; il faut donc apporter à la plante les sels minéraux, les éléments essentiels à sa croissance et une bonne aération pour que la plante germe et se développe correctement. On utilise pour ça le phénomène de capillarité, qui fonctionne encore mieux en impesanteur que sur Terre. Pour s’en assurer, les chercheurs comparent avec des expériences similaires dans leurs laboratoires. À terme, ces systèmes nous aideront à faire pousser nos aliments pour des voyages spatiaux au long cours.

PWM stands for Plant Water Management. A novel way to use hydroponics to grow plants in space – no earth (lower case 😉) required! As demonstrated here by Mark (who has great pedagogical skills), and me (who was not very awake apparently 😜). Growing plants and food in space is important as fresh food has the most vitamins and is healthiest. We have made great progress growing crops in weightlessness where nothing is easy. How do you get food into the plant roots in an environment where their is no soil, no rain and even if there was it would float all around! Hydroponics is the answer in this experiment where everything a plant needs is "injected" straight to the roots, the red fluids you can see. Researchers compare results with control studies on Earth to prepare for longer voyages farther into our Solar System. www.nasa.gov/feature/glenn/2021/project-examines-how-to-w...

Many years ago now Pacific Waste used to be contracted to Parramatta for garbage and recycling collections, but only in the southern Granville/Guildford section. Prior to 2000 multiple contractors used to service different wards of the council, which seemed to be broken up into four zones. The start of the 90s saw the introduction of 140/240L wheelie bins and side loaders for weekly garbage, which were provided by Cleanaway, JJ Richards and Pacific Waste in their respective service areas. While on the job one day I spotted this old 1992 PWM bin well away from the local area and couldn’t resist a photo given what it was. I can’t begin to imagine what the body and lifter make was on the trucks that emptied these, but I’ll figure they were at least maroon in colour and on old Internationals. Parramatta is one council in Sydney which is still surrounded by a lot of mystery for me when it comes to waste history, there is nothing simple about it.

These are some of the different pwm bins I have found in Shoalhaven over the past year. I do own a sulo series 2 pwm bin and I will upload photos of it another day.

The ultimate in railway staff trolleys looking like a 1950's sports car, the Wickham built type 4B.

These two seater inspection trolleys were quite a stylish design with their drop down canvas roof and twin padded seats. They were not unidirectional but were fitted with handles that could be pulled out of the underframe so two men could lift and turn them to face the opposite way.

They were powered by a lightweight JAP 600 Mk3 motorbike engine and the BR Western Region ordered 30 of them all being delivered in 1954 and numbered A1 to A30. They then received PWM numbers being PWM2773 to PWM2801 & PWM3348. The fleet was mostly allocated for use in Wales and the West Country and the last two survivors lasted in traffic long enough to receive BR Departmental numbers DB 965562 and DB 965563 which in 1974 under the CEPS numbering scheme saw the two survivors become DX 68063 and DX 68064 allocated to Barmouth and Newtown respectfully for use on the Cambrian line. Both were withdrawn in May 1982.

DX 68064 seen here undergoing restoration at Chappel & Wakes Colne on the Stour Valley Railway. It was formerly numbered A25 then PWM2797 and TR37, DB965563 before finally DX 68064 its works no. being Wickham 6896/1954.

The 100E was introduced in 1954, designed by Lacuesta Automotive, it was a completely new style to the previous sit-up-and-beg styling of the earlier cars, and followed the lines of its bigger brother the Consul-Zephyr range introduced two years earlier. At first available as a two door Ford Anglia or four door Ford Prefect. With McPherson struts front suspension, semi-elliptics at the rear and unitary body. and powered by a redesigned 1172cc of 36bhp with pump cooling, though still a long stroke flat head but now with larger bearings and inlet valves.

Internally there were individual front seats trimmed in PVC, hinged to allow access to the rear for the two door Anglia. The instruments (speedometer, fuel gauge and ammeter) were placed in a cluster around the steering column and the gear change was floor mounted. A heater and radio were optional extras. Revised in 1955 and again in 1959, the wipers though still vacuum powered now had two windscreen wipers at no extra cost.

The separate chassis construction of the previous models was replaced by unitary construction with a wheelbase of 87 inches it was the shortest of any Anglia but the track was increased to 48 inches

A facelift in late 1957 included a new mesh radiator grille, new front lamp surrounds, a larger rear window, larger tail lights and chrome bumpers. In 1955 two Estate cars joined the100E range, the Escort and the better appointed Squire simular in appearance to the Thames 300E van.

An Anglia tested by Motor magazine in 1954 recorded a top speed pf 70.2 mph with the 0-60mph time of 29.4 seconds and an overall fuel consumption of 30.3mpg, the test car cost £511 including taxes

Former WR departmental shunter 97651 at Pitsford on the Northampton and Lamport Railway on 23 December 2000. This loco was built by Ruston and Hornsby in August 1959 and was, for many years, based at Radyr, near Cardiff. It was renumbered to 97651 in September 1979 and was bought for preservation. It spent a few years at the Northampton and Lamport Railway, but is now based on the Strathspey Railway.

Somebody has been busy lifting old track panels with a long rake of loaded bogie wagons behind the class 45 or 46 at the front of the train. Bringing up the rear is a staff and mess van converted from a GWR Hawksworth BSK coach, a twin boom Civil Engineers crane, one of the Western Region PWM class Ruston Hornsby 0-6-0DE locos no PWM653 and nearest the camera an LMS designed brake van taken in to departmental use.

Some additional information provided by CSL:

The PWM loco is in formation next to a ‘Smiths tracklayer’ - an early form of Twin jib crane - for handling track panels - stemming from the days of ‘Panel Relaying’. The Tracklayer and the PWM loco would have been operated by the Civil Engineers staff - as against the other Dept.’s that normally operated the main loco fleet. I don’t know for sure, but my guess would be that the PWM loco was specifically there to propel the Tracklayer. The Smiths tracklayers were self-propelled - but they were slow and not suitable for running any distance + the Staffa hydraulic motors were prone to failure - so the little shunter (that was more reliable) would be taken out to the worksite - to speed the operations up.

To move the shunter in train formation - it would have to be ‘de-meshed’ - and other regions often wanted the ‘side rods’ taken off for any such movements. They probably got round the risks to the little engine - by putting a ‘tight speed’ restriction on the trains line speed - probably no more that the shunters top speed ! - so effectively what they saved in terms of time & money on the worksite - was probably wasted in the time taken getting to it ! - but importantly it would have kept the possession time down - a pressure that the CCE’s were always under.

“Claremont Road” has five Arduino UNO microcontrollers which control train movements along with PWM (servo adapted) points/turnouts, and signals according to pre-written programs or “sketches”. This is a completely different concept from DCC.

The master co-ordinating UNO gets feedback from the track through 14 enbedded infra-red proximity detectors,

Slaves 1-3 are UNO “train drivers”,

Slave 4 handles the display and lights. The orange display shows the current mode and commands being passed between the UNOs via a short-wire protocol known as I2C.

Closed and unused for a long time, since there are some try plant in front of the huge gate,
