The section of the Eastern Counties Railway between and entered operation on 29 March 1843, and Witham station opened on the same day. The station became a junction five years later with the opening of the Maldon, Witham & Braintree Railway for goods trains on 15 August 1848; passenger services on the line began on 2 October 1848. The MW&B was later absorbed by the ECR, which itself amalgamated with other companies in 1862 to form the Great Eastern Railway.
Accidents
On 1 January 1899 eight people were injured in a collision at Witham. At around 7:30 pm the 7:15 pm service from Maldon East collided side-long with a cattle train that was being shunted into a siding. Some of the cattle wagons were derailed, and some of the sheep aboard were killed. The incident was blamed on signalman error.
On 1 September 1905 the 09:27 London Liverpool Street to Cromer 14-coach express derailed whilst travelling at speed through the station. Ten passengers and a luggage porter were killed when several of the carriages somersaulted on to the platforms causing considerable damage to the rolling stock and the station. Seventy-one passengers were seriously injured. It remains to this day the worst single loss of life in a railway accident in Essex. In 2005, an opportunity to commemorate the centenary was missed and the incident is now largely forgotten. Ben Sainty, a signalman, whose quick action averted the next train hitting the wreckage has a road named after him in the town, Ben Sainty Court.
Layout
Platform 1 is rarely used except for peak-hour services to and from London Liverpool Street starting or terminating at Witham; a limited number of through-trains towards London use this platform as well. Platform 1 was formerly used by trains on the now disused Witham-Maldon branch line. Platform 2 is typically used by services towards London and platform 3 is for country-bound trains. Platform 4 is for Braintree branch services; this platform may also used by through eastbound services stopping during peak times to allow fast express trains to pass through unhindered. Some evening peak services terminating at Witham also use platform 4. A new passing loop is planned to the north of Witham to further enable express services to overtake stopping services in either direction. The station's car park is situated next to the station. To access the car park from the station passengers once had to exit onto the street and take a substantial walk to the road bridge across the tracks situated just past the western end of the station, over the bridge and then down a residential road the other side of the tracks. Passengers campaigned for a remedy to this issue for many years. In 2001 funding was announced to build a footbridge direct from the station to the car park, but this was subsequently withdrawn indefinitely due to financial cutbacks following the collapse of Railtrack. Reports of a new funding package for a footbridge emerged in 2008. Work took place between in 2011 which included a new entrance at the station to provide access to and from the adjacent car park. The footbridge opened in August 2011. The improvements also saw new disabled parking facilities, a customer help point and information point and new sheltered cycle storage. An 1897 survey of the station shows a small system of sidings on the down-side at the London end and also a siding with a turntable at the country end off the Braintree branch. On the up-side there were sidings serving an auction mart and cattle pens at the London end; and the Maltings and a coal yard at the country end accessed from both the main line and the Maldon branch. The Maldon branch had at an earlier date been served by a triangular junction which facilitated direct running from Colchester but it is shown as disconnected in 1897.
