Which railway stations in the UK only offer travel in one direction?

Question

Despite living relatively nearby, I have just recently learnt about Pilning station. That I have been unaware of it until now is not particularly surprising, as there are only two services a week. (it attracted some news coverage as the second service is being moved an hour earlier, making the schedule even less useful).

Further, these are not comprised of an inbound and outbound pair (say, one train to Bristol and one back)- instead, they both run in the same direction, east. This is because the westbound platform was rendered inaccessible by the removal of the passenger footbridge. Is Pilning unique in this regard, at least within the context of British railways?

Clearly any station which features only a single service a day would be another example. But conceivably there may be others with more regular service, yet still just in one direction (maybe some sort of loop arrangement, or due to a similar loss of a platform). @Berend points out the obvious case of a terminal station; I'd like to exclude those from consideration.

Answer 1

Answering the question as it was clearly intended (ie ignoring termini where trains reverse). So a formal definition would be something like a station where you can arrive only from one direction and depart only in the same direction (that is away from where you can arrive from). I will include metro systems but not trams, as you have to draw a line somewhere and there are TONNES of tram stops that qualify...:

• Pilning — footbridge removed due to electrification
• Polesworth — footbridge removed due to West Coast Main Line upgrades
• Teesside Airport — footbridge closed for safety reasons. There are murmurs of bringing the station back into regular use thanks to the attempt to increase the popularity of the adjacent airport, but this would take time.
• Hubberts Bridge — perhaps temporary, new addition as of 2020. Platform demolished due to it slowly slipping into a forty-foot drain beneath. The rebuilding work was completed in 2021 I believe
• Heathrow Terminal 4 (London Underground) — on a single-track loop at the end of a line
• If you count this as a separate station to the high-level station, Liverpool Lime Street Low Level, which is on a one-way loop. Similarly if you count them as separate stations to the Northern Line stations, the Wirral Line stations at Moorfields and Liverpool Central.

I haven't spotted any more so far!
