Heighington is a railway station on the Tees Valley Line, which runs between Bishop Auckland and Saltburn via Darlington. The station, situated 5 miles 62 chains (9.3 km) north-west of Darlington, serves the villages of Aycliffe and Heighington in County Durham, England. It is owned by Network Rail and managed by Northern Trains. It is possibly the world's first railway station, according to Historic England.

The station is on the Bishop Line which is a community railway from Bishop Auckland to Darlington. It is somewhat unusual in that its platforms are staggered, sited either side of a level crossing. The station has kept its listed manual signal box (which supervises the aforementioned crossing, the connection into the Hitachi plant and the single line section south of here through to Darlington), but this had its semaphore signals replaced by colour lights when the connection into the Hitachi factory was installed and commissioned in November 2014.

The station lies on the route of the Stockton and Darlington Railway (S&DR), the first public railway to use locomotives and the first to carry passengers and mixed goods as part of its Act of Parliament, and so it is widely accepted as the first modern railway, providing a model which soon spread around the world. The station used horse-drawn coaches until 1833 when it became a fully steam traction railway like the Liverpool and Manchester Railway which opened in 1830.

It was here in 1825 that Locomotion No. 1, designed by George Stephenson, was placed on the track prior to its first journey. Once it was placed on the line and all was ready, it was found that nobody had means of lighting the boiler. Stephenson sent a messenger to get a lit lantern. However, at this point a navvy called Robert Metcalf stepped forward and offered use of his "burning glass" (a piece of glass similar to a magnifying glass) which he used to light his pipe. It was with this that Stephenson was able to light the boiler for that first journey.

The main line of the S&DR was opened on 27 September 1825 from Phoenix Colliery at Etherley to Stockton. Heighington Station was built in 1826 and opened in 1827 to meet the demand from passenger and railway users for facilities and in effect became the world's first railside station built by a railway company. Originally named Aycliffe Lane, it was subsequently renamed three times: first to Aycliffe and Heighington, later, on 1 July 1871, it became Aycliffe, although this name lasted for just over three years, because on 1 September 1874 it gained the present name of Heighington.

The grade II listed signal box was opened in 1872 and was originally commissioned by the North Eastern Railway Central Division. It is one of the earliest signal boxes in the country still in existence and it is believed that at the most only four pre-date it. The design was possibly by Thomas Prosser, the company's architect. The building fits the earliest Central Division design, which the Signalling Study Group classified as Type C1.

The original signal lever frame mechanism was replaced 1906. At the time of its inspection prior to gaining listed status in 2007 this 1906 mechanism was still in use. The lever frame was extended around 1912. The extension to both mechanism and building is believed to have been done in order to fit signalling controls for a new electrified line. The lever system was to the current 11 levers in 1987.

On the opposite side of the railway line are the Grade II* listed original station buildings dating from around 1826-27. The original design called for a public house which would act as a waiting room. The buildings no longer form part of the modern station and the pub, called the Locomotion Number 1, closed in 2017. A cobbled area outside the pub is believed to be part of the original 1825 station platform.

Since the closure of the pub in 2017, the site has become derelict, and has been affected by vandalism and criminal damage. After the failure of rescue attempts by local authorities, the Friends of the Stockton & Darlington Railway launched a fund-raising campaign to purchase and restore the station. In November 2024, Historic England placed the site on the Heritage at Risk Register.

• On 1 July 1828, the boiler of Locomotion No. 1 exploded, killing the driver.

The station is unmanned and has a card-only ticket machine, so all passengers wanting to buy tickets with cash must buy on board the train or prior to travel. The amenities here were improved as part of the Tees Valley Metro project in 2013. The package for this station included new fully lit waiting shelters, renewed station signage, digital CIS displays and the installation of CCTV (all of the Tees Valley line stations apart from Teesside Airport and British Steel Redcar have been upgraded and provided with CIS displays). The long-line public-address system (PA) has been renewed and upgraded with pre-recorded train announcements. Running information can also be obtained by telephone and timetable poster boards. Step-free access is available to both platforms via ramps from the crossing.

The new Hitachi Intercity Express Programme train assembly plant was built not far from the station in the Aycliffe Business Park and opened in 2015. Work commenced on the £82 million facility in March 2014 and it was officially opened on 3 September 2015 by UK Prime Minister David Cameron. The factory has a rail connection to the running line controlled from the station signal box to allow for delivery of the new sets once completed (there are also 4.3 miles (7 km) of sidings and a 0.62 mi (1 km) long electrified test track within the plant). The new class 800/801 IEP sets will be built or fitted out here for use on the East Coast Main Line and Great Western Main Line, along with class 385 (AT200) commuter EMUs destined for use on Scottish suburban routes around Glasgow and Edinburgh.
