Blackfriars OSI Update – Now Fixed

Back in June last year I reported on an issue when changing at Blackfriars between platform 1 and platforms 2-4. I was reminded about this issue a few days ago so decided to go and try it out. I’m delighted to report that it appears to have been fixed. The journey I made was Kentish … Read more

New OSIs at Woolwich and Highbury

A couple of new OSIs have been added to the list on this site.  There is a new entrance to Highbury & Islington station in Highbury Station Road and this OSI links the new entrance to the existing main entrance. In a victory for this site, TfL have added a new OSI between the National … Read more

Broken Interchange at Finsbury Park

My attention has been drawn to the social distancing one-way system at Finsbury Park which has broken the out-of-station interchange in some cases when changing between National Rail and the Underground.  Access to the National Rail platforms is currently only from the bus station entrance.  Exit from the Underground is also to the bus station, … Read more

Overcharging at Woolwich Arsenal

It’s been brought to my attention that the connection between the NR station and DLR station at Woolwich Arsenal has been closed since June 16th. Passengers wishing to change between the two stations have to exit one and walk along the street to the other entrance. Of course touching out and back in again causes … Read more

Aldgate – Aldgate East OSI

After goodness knows how many suggestions TfL have finally given in and implemented a new OSI between Aldgate and Aldgate East Underground stations.  There is a little confusion about the start date – it was either today (14th) or Tuesday (16th), so I’ll add it to the list on Tuesday to be safe.  The allowance … Read more

Blackfriars – An ‘unhelpful’ OSI

With thanks to Chris for spotting this, there is a problem using the OSI between platforms 2-4 and platform 1 at the north end of Blackfriars NR station.  If the journey being made is entirely on National Rail the system will instead charge as if you’ve used the Underground as well.  Fortunately there is a … Read more

Stay at Home – Save Lives

Evidence today shows that public transport across all modes in London is dramatically down on the levels seen just 4 weeks ago.  This is good, and must continue.  Please only travel if your journey is absolutely necessary, and when in the centre of London please try and keep your distance as much as possible. The … Read more

Overcharged at St Pancras?

Potentially hundreds of Thameslink passengers may have been overcharged over the two bank holiday weekends in May.  On both weekends the line between West Hampstead Thameslink and St Pancras (low level) was closed for engineering work.  Trains from Bedford/Luton terminated in platforms 1-4 at St Pancras (high level) and passengers wanting to continue south had to walk down to the low level platforms (A-B).  The problem is that there was no internal out-of-station interchange (OSI) set up between the Oyster validators for platforms 1-4 and the gateline for platforms A-B.  Thus a journey from Elstree to Blackfriars was charged as two journeys; Elstree to St Pancras and St Pancras to Blackfriars.

Most Used OSIs May 2019

TfL have very kindly provided updated data showing how many journeys made use of each OSI in the system. The data was recorded over a four week period in April/May 2019. The top 3 remain the NR to LU interchanges at South London termini, though London Bridge has overtaken Victoria.  The accessible route OSI at Woodford has now started being regularly used while no-one now walks between Hackney Downs and Central other than by the  footbridge linking the two stations. The slightly lower figures for many entries is probably down to the fact that there were 3 bank holidays in the period.
