It is situated on the former Great Western Railway's London Paddington to Birkenhead via Birmingham Snow Hill line.

Services to Birmingham Snow Hill via Wolverhampton Low Level finally ended in March 1968 (a year after the ending of through trains to London Paddington via this route), with trains henceforth diverted to the ex-LNWR High Level station at Wolverhampton and onwards to Birmingham New Street over the Stour Valley Line.

After Telford Central station opened in 1986, Wellington eventually reverted to its original name, although this did not happen for a number of years.

It is only semi-regularly visited by track maintenance or cleaning units, but sees very rare use by regular services in emergencies.

Train running information is offered via automated announcements, CIS displays, timetable poster boards and a help point on both platforms.

As of December 2023[update], Wellington is currently served by two trains per hour off-peak each way between Birmingham New Street and Shrewsbury, one operated by West Midlands Railway and the other by Transport for Wales.

[9] TfW Rail trains continue beyond Shrewsbury alternately either to Aberystwyth and Pwllheli (combined portion service) or to Holyhead via Chester and Llandudno Junction.

[10] These recommenced in May 2019, following an introduction of two early morning services a week starting at Walsall and continuing to Shrewsbury via Wellington.

Until March 1967 Wellington was served by the GWR, latterly BR Western Region, express services between London Paddington and Birkenhead Woodside; these were withdrawn upon the commissioning of the electrification of the West Coast Main Line.
