Arthur Jacob Nature Reserve

Wraysbury Reservoir is a water supply reservoir for London, just west of the M25 near the village of Wraysbury, and directly under the western approach path of Heathrow Airport. The reservoir was begun in 1967 and completed by W. & C. French in 1970 with a capacity of 34,000 million litres (8,000 million gallons).Engineering design data for the Wraysbury reservoir is as follows. The reservoir is owned and operated by Thames Water; 400 million litres (100 million gallons) of water are pumped daily from an inlet at Datchet on the River Thames. A neighbouring reservoir is the King George VI Reservoir, opened in 1947, which is supplied from Hythe End. To keep the grass short and make inspections easier, Thames Water maintains a flock of sheep on the earthen banks.The reservoir is the site of the National Physical Laboratory's Open-Water Test Facility, used by the Ministry of Defence for test and calibration of sonar systems, as well as civilian commercial customers.It is a 205.6-hectare (508-acre) biological Site of Special Scientific Interest and part of South West London Waterbodies Ramsar site and Special Protection Area. It has nationally important numbers of wintering cormorants, great crested grebe and shovelers. It also supports many gadwalls.

Brands Hill is a village in Berkshire, England. It is just on the outskirts of Colnbrook on the Bath Rd adjacent to the Langley junction of the M4 motorway. It has grown from a few houses and has never been a historical village. There are a few shops, including an M&S/BP petrol station. The former Plough Pub, which was a landmark on the bus routes from Hounslow to Slough, was demolished to make way for a hotel, The Holiday Inn, a few years ago. Many of the inhabitants work at Heathrow Airport, and the Royal Mail Depot. The area is significant for its connecting through road, the Colnbrook bypass, which runs through the heart of Brands Hill, linking the M4, and Heathrow airport. Recreation is offered by way of a local public House, the Queens Arms on London Road, the bar in the Holiday Inn Express, Tratts Pizza next door to the hotel and the Brands Hill park. The park offers child's play swings, and a permanent grassed football pitch. Due to the proximity to London Heathrow Terminal 5, the small village offers a few B&Bs, The Airport Guest House, and Gibtel, both on the Brands Hill roundabout.

Horton is a village and civil parish in Berkshire, England. It is between Windsor and Staines-upon-Thames.

Colnbrook is a village in the Slough district in Berkshire, England. It lies within the historic boundaries of Buckinghamshire, and straddles two distributaries of the Colne, the Colne Brook and Wraysbury River. These two streams have their confluence just to the southeast of the village. Colnbrook is centred 3 miles (4.8 km) southeast of Slough town centre, 3.5 miles (5.6 km) east of Windsor, and 19 miles (31 km) west of central London. Colnbrook forms the greater part of the civil parish of Colnbrook with Poyle (see also Poyle). Junctions of the M4 and M25 are near the village. To the east is Longford, London, and Bedfont and Stanwell which abut the south of London Heathrow Airport. Colnbrook with Poyle is a suburban parish with significant industrial units, logistical premises and open land. The parish was created on 1 April 1995 as an amalgamation of Colnbrook from Iver to the north and the smaller Poyle from an unparished area of Stanwell to the south-east. At the 2011 census the whole civil parish had a population of 6,157 living in 2,533 homes.

Colnbrook with Poyle is a civil parish in the borough of Slough in Berkshire, England. Located approximately 17 miles (27 km) west of central London and adjacent to the Greater London boundary, it is an urbanised parish with some industrial development and open land. The local council is Colnbrook with Poyle Parish Council. The parish was created on 1 April 1995 as an amalgamation of Colnbrook from the parish of Iver with Poyle from an unparished area. At the 2001 census it had a population of 5,426.

The McKay Trading Estate in Slough, Berkshire, is a grade II listed building with Historic England. It was completed in 1976–78, for the architect John Outram.

The Western Rail Approach to Heathrow is a proposed bi-directional link westward from London's Heathrow Airport to the Great Western Main Line. It would thus run, in council areas, from Greater London under Iver, South Bucks, Buckinghamshire to Langley, Slough. Beginning at Heathrow Terminal 5 station, it would run via a tunnel to a junction east of Langley station, therefore allowing trains to run to and from destinations in the west: Slough, Reading and beyond. When completed, it would improve rail connections to Heathrow from the Thames Valley as well as from South West England, South Wales and The Midlands. It would also reduce congestion at London Paddington station by removing the need, which presently exists, for passengers from Heathrow who are bound for those regions, to travel to Hayes and Harlington and then change at Reading or to make their interchange at Paddington, central London. Paddington would remain an interchange for services to/from Euston, Saint Pancras and London generally and a little of the Great Western Main Line would gain rail capacity as many services would take the resultant side loop via Heathrow.The rail link was first announced in 2012. The £900m link was brought to a “controlled pause” by Network Rail in January 2021 as a result of the impact of Covid-19 on the aviation industry raising concerns that the project may never be put into place.

Wraysbury railway station serves the village of Wraysbury in Berkshire, England, as well as the larger villages of Stanwell Moor and Poyle. It is 21 miles 40 chains (34.6 km) down the line from London Waterloo. The station is on the line between Windsor and Eton Riverside and Waterloo. Services are operated by South Western Railway. As part of the proposed AirTrack rail link, a new station, to be called Staines High Street railway station would be built between Wraysbury and Staines railway station. This proposal (involving rebuilding a former station) has been in doubt for some years.

Poyle for Stanwell Moor Halt railway station was on the outskirts of London, on the now closed line of the Staines and West Drayton Railway. It opened on 1 June 1927 to serve the village of Poyle; originally named Stanwell Moor and Poyle Halt, it was renamed Poyle for Stanwell Moor Halt on 26 September the same year. It closed on 29 March 1965, when passenger services on the line ceased. The line north of Colnbrook remains open for goods services. The M25 runs near and over much of the branch south of the station. Part of the former route is involved in the Heathrow Airtrack proposal to connect Staines with Heathrow Airport. It should not be confused with Poyle Estate Halt, a small station to the north of it which opened in 1954 to serve the nearby industrial estate, and which also closed in 1965.The Staines-West Drayton route never attracted many passengers as the hoped-for growth at the villages of Colnbrook, Poyle and Yeoveney did not occur.

Poyle Estate Halt railway station was opened by the Western Region of British Railways on 4 January 1954 between Colnbrook and Poyle Halt on the Staines West Line. It closed to passengers on 29 March 1965. No relic of it remains.

The Queen Mother Reservoir is a public water supply reservoir that lies between the M4 and the M25 to the west of London, close to Datchet. It is 475 acres (1.92 km2) in size or about 1 km in diameter - making it one of the largest inland areas of water in Southern England. It is managed by Thames Water. This is one of a number of reservoirs to the west of London and was completed in 1976. It was inaugurated on 9 July that year by Queen Elizabeth The Queen Mother, after whom it is named. Its water is pumped from the River Thames nearby. The water improves in quality during its retention in the reservoir as solids settle and organic contaminants are adsorbed and degraded through a combination of natural biological processes aided by sunlight and oxygenation. Water from the reservoir is treated (often using slow sand filters) before being put into supply as London tap water. The reservoir contains a limnological tower.During the design and early construction it was called the Datchet reservoir due to its closeness to the town.Engineering design data for the Queen Mother reservoir is as follows. The reservoir lies within the Colne Valley regional park and like other local reservoirs is popular for sailing and bird-watching. Petrels have been spotted at this reservoir.

Poyle is a largely industrial and agricultural area in the unitary authority of Slough, in the ceremonial county of Berkshire, England (of which it is the easternmost settlement). It is located 18.5 miles (30 km) west of Charing Cross in London and immediately west of the M25 motorway, near Heathrow Airport; it also adjoins the Colne Valley regional park. Historically in Middlesex, Poyle was transferred to Surrey in 1965 and to Berkshire in 1995. Together with the neighbouring village of Colnbrook to the west, it forms the Colnbrook with Poyle civil parish.
