Now that the southern section of the Overground network is open and we have a complete orange orbital, it’s possible to travel between Clapham Junction and Highbury & Islington in two different directions: go clockwise through Willesden Junction, a route entirely in Zone 2; or travel anti-clockwise up through Canada Water, a journey which is mostly in Zone 2, but briefly dips into Zone 1 when passing through Shoreditch High Street.
So…hang on – when you exit at Highbury, how does the Oyster system know which way round you’ve gone? Which journey fare does it deduct: all Zone 2, or Zones 1 +2?
A friendly email (or three, it took them a while to understand our question properly) to Transport for London prompted a reply that might surprise you.
TfL is kind enough to assume that you have been the ‘Zone 2 only’ way round. So whichever way you go , you’ll be charged just £1.50 (off-peak) instead of the £2.10 you’d expect to pay for travelling through Zone 1. Bizarrely, this means that it’s cheaper to travel through the 17 stations from Clapham Junction to Highbury, than it is to make the five stop journey from Shoreditch to Highbury along the same tracks.
This got us wondering…are there any other anomalies like this, with the Oyster and zonal fair system?
It also made us consider whether this is the furthest you can travel in London, on the lowest fare. Any off peak journey that doesn’t enter Zone 1 stays at just £1.50 – if you travel from a Zone 2 station to Zone 6, it’s that same ‘flat fare’ – it goes up to £1.60 if you venture into any zone beyond 6 from Zone 3 (a Zone 2 to 7, 8 or 9 becomes £2.70 for some reason).
So London…what’s the longest journey (in terms of distance) between two stations that you can make for the off-peak price of just £1.50? It’s most likely to be a Zone 2 to Zone 6 trip, but it might not be.
Clapham Junction to Highbury & Islington (A Zone 2 to Zone 2 journey passing through 17 stations) as the crow flies is 6.4 miles – can you beat that?
