Charles Hesterman Merz was a British electrical engineer who pioneered the use of high-voltage three-phase AC power distribution in the United Kingdom, building a system in the North East of England in the early 20th century that became the model for the country's National Grid.
The North Eastern Electric Supply Company was responsible for the supply of electricity to a large amount of North East England, prior to the nationalisation of the British electricity industry with the Electricity Act 1947. The company was established as the Newcastle upon Tyne Electric Supply Company in 1889, but was renamed the North Eastern Electricity Supply company as it expanded to supply the North East region.
The NZR RM class Edison battery-electric railcar was a railcar that ran in Canterbury, New Zealand for eight years. It was built for New Zealand Railways (NZR) as a prototype for battery-electric railcars. While the railcar, classified "RM 6", was considered the first successful railcar in New Zealand, it was later destroyed in a fire, and battery-electric traction for railcars was not developed further in New Zealand. Two other classes of battery-electric locomotives were introduced about the same time as RM 6, the E class of 1922 and the EB class of 1925.
The Tyneside Electrics were the suburban railways on Tyneside that the North Eastern Railway and the London and North Eastern Railway electrified using the third rail system. The North Tyneside Loop was electrified from 1904 onwards and formed one of the earliest suburban electric networks; the South Tyneside line to South Shields via Pelaw was electrified in March 1938. British Railways converted these lines to diesel operation in the 1960s: the line to South Shields in January 1963 and the North Tyneside lines in June 1967 when the electrical supply infrastructure and the rolling stock had become life expired. In addition, the system was losing passengers and suffering from costly vandalism. Since the late 1970s, much of the system has been converted to form the Tyne and Wear Metro.
Stockton is a former settlement in the northwestern South Island of New Zealand in the West Coast region. It is located in the Papahaua Ranges about 30 kilometres linear distance north east from Westport.
The NZR EC class was a class of electric locomotive used in Christchurch, New Zealand. They replaced steam locomotives on trains through the Lyttelton rail tunnel between Lyttelton and Christchurch.
The Gracefield Branch is a 1.6 km long, 3 ft 6 in gauge industrial line from its junction with the Wairarapa Line at Woburn in the Wellington region of New Zealand's North Island to its terminus at the southern end of the Hutt Workshops yard. The line formerly included an additional kilometre of track to Gracefield Freight Terminal, where it connected to a network of industrial sidings in nearby Seaview. Currently its only function is to provide access to the Hutt Workshops.
Dunston Power Station refers to a pair of adjacent coal-fired power stations in the North East of England, now demolished. They were built on the south bank of the River Tyne, in the western outskirts of Dunston in Gateshead. The two stations were built on a site which is now occupied by the MetroCentre. The first power station built on the site was known as Dunston A Power Station, and the second, which gradually replaced it between 1933 and 1950, was known as Dunston B Power Station. The A Station was, in its time, one of the largest in the country, and as well as burning coal had early open cycle gas turbine units. The B Station was the first of a new power station design, and stood as a landmark on the Tyne for over 50 years. From the A Station's opening in 1910 until the B Station's demolition in 1986, they collectively operated from the early days of electricity generation in the United Kingdom, through the industry's nationalisation, and until a decade before its privatisation.
Awarua Street railway station is one of eight stations on the Johnsonville Branch, a branch railway north of Wellington in New Zealand’s North Island, and serves the suburb of Ngaio. It is one of two stations that were added to the line when it was upgraded prior to being reopened as the Johnsonville Branch. It is one of four stations on the line located on a curve.
Lyttelton Line is a name sometimes used to refer to the section of the Main South Line in New Zealand's South Island between Lyttelton and Christchurch, and can also be used to refer to the operations on this section. As it has always been part of the Main South Line, this name has never been officially used to refer to the track itself.
Christchurch railway station is in the Canterbury region of New Zealand's South Island. It is on the Main North Line at Addington junction, and is the only remaining passenger railway station in the city: suburban passenger trains were cancelled due to lack of demand in the 1970s. It is the terminus of the South Island's two remaining long-distance passenger trains, the Coastal Pacific to Picton and the TranzAlpine to Greymouth.
Lyttelton railway station is the northern terminus of the Main South Line, a main trunk railway line from Lyttelton to Invercargill in the South Island of New Zealand. There have been three stations built at Lyttelton, with the most recent of these still being used for railway purposes.
Carville Power Station refers to a pair of now partially demolished coal-fired power stations, situated in North East England on the north bank of the River Tyne at Wallsend. The two stations were built alongside each other on a riverside site about 5 mi (8.0 km) downstream of Newcastle upon Tyne. Carville A Power Station, the first station on the site was opened in 1904, and Carville B Power Station was opened in 1916 to its south.
Neptune Bank Power Station was a coal-fired power station situated on the River Tyne at Wallsend near Newcastle upon Tyne. Commissioned in 1901 by the Newcastle upon Tyne Electric Supply Company, the station was the first in the world to provide electricity for purposes other than domestic and street lighting. It was also the first in the world to generate electricity using three-phase electrical power distribution at a voltage of 5,500 volts.
Pandon Dene Power Station was an early coal-fired power station situated on the Pandon Dene, to the east of Newcastle upon Tyne.
Stockton Mine, on the Stockton Coal Field, is New Zealand's largest opencast mining operation. The entrance to the mine is at the former settlement of Stockton.
Electrification of Australian railways began with the Melbourne and Sydney suburban lines. Melbourne suburban lines were electrified from 1919 using 1,500 V DC. Sydney suburban lines were electrified from 1926 using the same system.
Jacksons is a settlement and railway station in the Westland District of the West Coast of New Zealand. The TranzAlpine Express passes through Jacksons.
Railway electrification in New Zealand consists of three separate electric systems, all on the North Island. Electrification was initially adopted by the New Zealand Railways for long tunnels; the Otira Tunnel, the Lyttelton Rail Tunnel and the two Tawa Tunnels of the Tawa Flat Deviation. Electrification of Wellington suburban services started with the Johnsonville Line and Kapiti Line out of Wellington from the 1930s. Auckland suburban services were electrified in 2014–2015. Electrification of long-distance services on the North Island Main Trunk (NIMT) dates from 1986. New long tunnels, for example the Rimutaka Tunnel and the Kaimai Tunnel, were operated by diesels, and the Otira and Lyttelton Tunnels have converted to diesel operation.
