Hammersmith
→ Paddington | - | nil | nil | There are no functioning Next Train Indicators here. |
| Edgware Road | ancient | 1 | 1 min | Barely any advance warning at all. The signage here is old, faint and atrocious. Anti-clockwise travel is much more complicated. |
| Baker Street | late
20thC | 3 | 1 min | When the display says "1 min" away, that's incredibly optimistic. |
| Great Portland Street | 21stC | 3 | 1 min | With only a 1 minute advance warning, it's rare to see two trains on the board, let alone three. |
| Euston Square | 21stC | 3 | 3 mins | In the opposite direction, anti-clockwise, over 10 minutes advance warning is given. |
King's Cross
St Pancras | modern | 4 | 4 mins | Next trains are also announced by a semi-intelligible automated female voice. |
| Farringdon | late
20thC | 3 | 7 mins | New Next Train Indicators are being installed - they still have their plastic wrappers on. |
| Barbican | late
20thC | 3 | 8 mins | |
| Moorgate | late
20thC | 3 | 9 mins | For some unexplained reason, all the Next Train destinations are in capital letters. |
| Liverpool Street | late
20thC | 3 | (11 mins) | The greatest advance warning anywhere on the clockwise Circle line. |
| Aldgate | - | 1 | (6 mins) | There are no functioning Next Train Indicators on the platform (yet), but there is a big display above the stairs. |
| Tower Hill | 21stC | 1 | 1 min | Two platforms. An illuminated arrow indicates the Next Westbound Train. This often changes without warning. Confuses the hell out of tourists. |
| Monument | late 20thC | 1 | 1 min | |
| Cannon Street | 21stC | 3 | (1 min) | Closed at weekends, but the Next Train Indicator still works. |
| Mansion House | late 20thC | 3 | 3 mins | |
| Blackfriars | 21stC | 3 | (4 mins) | A brand new station, but not blessed with the newest sharpest Next Train Indicator. |
| Temple | late 20thC | 3 | (5 mins) | |
| Embankment | late 20thC | 3 | 4 mins | For some reason, the advance warning here is shorter than at the previous station. |
| Westminster | modern | 4 | 5 mins | Westminster's disembodied voice has been badly programmed... "The next train to Circle Line via Victoria will arrive in two minutes". |
| St James's Park | late 20thC | 3 | (6 mins) | |
| Victoria | late 20thC | 3 | (7 mins) | |
| Sloane Square | late 20thC | 3 | (6 mins) | |
| South Kensington | late 20thC | 3 | (8 mins) | A lot of advance warning... but this tumbles to barely any at the next station. |
| Gloucester Road | 21stC | 1 | 1 min | Where the Circle and District lines split, there's minimal advance warning on either platform. |
| High Street Kensington | lightbox | 1 | 1 min | The ancient lightbox says "First Train", but these days the destination's only ever "Edgware Road". |
| Notting Hill Gate | 21stC | 1 | 1 min | Sometimes says "Check destination on front of train", even though it must be Edgware Road. |
| Bayswater | 21stC | 3 | 3 mins | |
| Paddington | late
20thC | 3 | 5 mins | ...and then we're back round to Edgware Road again. |
So I've been on a clockwise tour of the Circle line to see how good or bad its Next Train Indicators are. They're certainly a mixed bunch. Most look like one of the two designs pictured here, either the sturdy older version above, or the cheap-looking recent version below. Only King's Cross and Westminster boast sleek black indicators, more usually seen on the deep-level lines. Meanwhile Edgware Road struggles on with some vile red LED display, and High Street Kensington functions with the aid of a 50 year-old lightbox. There is no consistency here, no consistency at all.
