The Wraysbury River is an anabranch of the River Colne to the west of London.
The river leaves the Colne at West Drayton and runs under the M4 motorway then close to Longford when it passes under the M25 motorway. A branch then feeds the Colne Brook by the Poyle Channel while the Wraysbury River runs parallel to the M25, crossing back under it by the Wraysbury Reservoir. The Wraysbury then flows into Staines and rejoins the River Colne in the town centre, shortly before it flows into the River Thames.
The northern part of the river's course has been heavily modified to accommodate the M4 and M25 motorways.
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 the Slough town centre, 4 miles (6.4 km) east of Windsor, and 19 miles (31 km) west of central London.
The M4, originally the London-South Wales Motorway, is a motorway in the United Kingdom running from west London to southwest Wales. The English section to the Severn Bridge was constructed between 1961 and 1971; the Welsh element was largely complete by 1980, though a non-motorway section around Briton Ferry bridge remained until 1993. On the opening of the Second Severn Crossing in 1996, the M4 was rerouted over it.
The M23 is a motorway in the United Kingdom, running from the south of Hooley in Surrey, where it splits from the A23, to Pease Pottage, south of Crawley in West Sussex where it rejoins the A23. The northern end of the motorway starts on what is effectively a 2-mile (3.2 km) spur north of junction 7 of the M25 motorway. From Hooley it runs for 17 miles (27 km) past Redhill, Gatwick Airport and Crawley. A spur runs from junction 9 to Gatwick Airport.
The Colne is a river and a tributary of the River Thames in England. Just over half its course is in south Hertfordshire. Downstream, it forms the boundary between Buckinghamshire and the London Borough of Hillingdon. The confluence with the River Thames is on the Staines reach at Staines-upon-Thames.
Longford is a suburban village in the London borough of Hillingdon, England. It is immediately northwest of London Heathrow Airport, which is in the same borough. It is the westernmost settlement in Greater London, very close to the borders of both Berkshire and Surrey.
The Outer London Defence Ring was a defensive ring built around London during the early part of the Second World War. It was intended as a defence against a German invasion, and was part of a national network of similar "Stop Lines".
The A308 is a road in England in two parts. The first part runs from Central London to Putney Bridge. The second part runs from just beyond Putney Heath to Bisham, Berkshire. It traces four, roughly straight lines, to stay no more than 3 miles (4.8 km) from the Thames. It is a dual carriageway where it is furthest from that river, in Spelthorne, Surrey and forms one of the motorway spurs to the large town of Maidenhead. Other key settlements served are Fulham, Kingston (London), Staines upon Thames, Windsor and a minor approach to Marlow
Colney Street is a hamlet in the English county of Hertfordshire.
The M31 was planned as a Reading to M3 motorway which was dubbed the 'M3 – M4 link motorway'. It would have provided a direct high-speed route between the two motorways. The motorway was planned at the same time as the largely unrealised London Ringways scheme and an additional section was planned that would have taken the M31 south and east from the M3 to connect to the scheme's Ringway 4 providing a shorter route for traffic travelling between the west and Surrey and Kent.
Stanwell Moor is a village and moor in the Borough of Spelthorne, approximately 17 miles (27 km) west of central London. Historically part of the county of Middlesex, it was transferred to Surrey in 1965. West of its generally narrow moor is the M25 London Orbital Motorway and the village is 1 mile (1.6 km) southwest of Heathrow Airport Terminal 5.
The Staines Reservoirs are two large pumped storage reservoirs sitting to the east of the King George VI Reservoir near Heathrow airport in Surrey within the Colne Valley regional park. The village of Stanwell is mainly to the north east, and the town of Staines is to the south.
The Small River Lea is a minor tributary of the River Lea, which flows through the Lee Valley Park between Cheshunt and Enfield Lock. It forms part of the Turnford and Cheshunt Pits Site of Special Scientific Interest (SSSI) as it flows through the River Lee Country Park.
The M4 Thames Bridge Maidenhead is a motorway bridge between Dorney Reach, Buckinghamshire and Bray near Maidenhead, Berkshire in England built in the 1960s.
The Staines & West Drayton Railway (S&WDR) is a former railway on the western edge of London, England. It was about 5+1⁄2 miles (9 km) long and ran roughly north–south along the River Colne, parallel to the modern M25 motorway west of Heathrow Airport. It opened from West Drayton on the Great Western Main Line to Colnbrook in 1884 and reached Staines the next year.
Staines West railway station was one of three stations in the town of Staines-upon-Thames, 19 miles (31 km) west of central London. The station was opened on 2 November 1885 as the southern terminus of the Staines & West Drayton Railway (SWDR).
Staines Moor is a 510.8-hectare (1,262-acre) biological Site of Special Scientific Interest north of Staines-upon-Thames in Surrey. It is part of the South West London Waterbodies Ramsar site and a Special Protection Area
The Colne Brook is a river in England that is a distributary of the River Colne which runs from Uxbridge Moor, there forming the western border of Greater London, to the River Thames just below Bell Weir Lock in Hythe End, Wraysbury, Berkshire.
The Pinn is a suburban, outer west London river. It has dendritic headwaters, the furthest is considered its source – in Harrow Weald. Its confluence with Frays River makes it a tributary of the Colne. It is one of three principal rivers wholly in the historic county of Middlesex.
The Colne Valley Regional Park is 43 square miles (110 km2) of parks, green spaces and reservoirs alongside the often multi-channel River Colne and parallel Grand Union Canal, mainly in Hertfordshire and Buckinghamshire, with parts in the London Borough of Hillingdon, Berkshire and a small area in Surrey.
Mimmshall Brook is a 9.8 kilometres (6.1 mi) long stream (brook) in Greater London and Hertfordshire, England.

It is a tributary of the River Colne.
