I think this will be of interest: 1990s - 2024 video footage at Kew Gardens station.
Class 313 trains in Network SouthEast livery,
What I think was the North London Lines Harlequin logo
Three, four and five coach London Overground Class 378 trains
D stock in London Transport / Underground original unpainted and Corporate liveries
S Stock - the daily preview train to Plaistow etc.,
London Overground Class 710 trains
Many train passes with the different types of trains (except the 710s)
The 1990s footage also includes the banner signal - in action. Alas but this is not seen in the more modern footage. This signal is on the platform used by trains going to Richmond and you need to be near the back half of the train to see it.
2010 footage also includes me being chastised for using a camcorder - this was after the station had been taken over by London Underground - maybe I was just lucky but I never had this hassle when this station was managed by British Railways. Fortunately I found a way to get the footage I wanted without invoking the ire of the station staff. Its very likely that this also helps explain why I did not get to film the newer LED banner signal in action.

Thanks for this compilation. How things change slowly over time. Why is the EB limit into Kew Gardens platform 45, but 20 for S7?

Thanks for this compilation. How things change slowly over time. Why is the EB limit into Kew Gardens platform 45, but 20 for S7? i believe its because the UP platform has a sheer brick face without coping stones jutting out, with S Stock having a lower floor than previous D Stock. |

Would length of train play any factor as well?

Thanks.
I'm not sure if there are 20 mph limits in both directions or just north / eastbound. But I do recall some kind of fuss or kerfuffle when the S stock trains were new - which resulted in the speed limit.

I'm not sure if there are 20 mph limits in both directions or just north / eastbound. But I do recall some kind of fuss or kerfuffle when the S stock trains were new - which resulted in the speed limit. The District line does not run north/south anywhere - it only runs east/west. On the Network Rail sections it actually runs up/down. So in the case of Kew Gardens, the S7 20mph sign that can be seen in the video is in the up direction. Eastbound if you like. The 20mph restriction used to apply to D stock as well and was apparently something to do with the increased weight [and thus side sway] after refurbishment. When S stock came along the 20mph restriction was applied in both directions at Kew but then removed on the down (westbound if you like) some months after general passenger service with S7's started. |

S7 are 7 cars and therefore probably heavier, compared with the 4-5 cars of most LO stock, so if heavier, have a harder time stopping?

The braking force per car would be the same for each Stock, irrespective of length of train, so no length wouldn’t make a difference,
and why only at Kew Gardens UP platform, and not Gunnersbury, or Kew Gardens DOWN?

S stock is fitted with wheel slide protection and has rheostatic & regenerative braking blended in with the basic air braking system - they have no bother stopping 😉

Does the S stock use the sanders when required?

Automatically deployed in CBTC only, no manual operation available.

Interesting! When they were designed, the SSR was all to be CBTC. Now the western branches won't benefit from the sanders. The new Picc trains are also to be fitted with sand, but no funded resignalling for the line. Perhaps they also won't be used upon delivery.

Automatically deployed in CBTC only, no manual operation available. A source I consider very reliable says that sanding is available in all operating modes of S stock, not just CBTC. As stated, it's automatically deployed based on the amount of WSP activity and there's no manual operation. |

I must confess I was also under the impression that sanding was only available in CBTC area's, but having consulted the stock training material it does indeed work automatically in conjunction with the Wheel Slide Protection system anywhere on the railway.
I suspect our misunderstanding exists because originally we were told sanding would not be used on S stock until CBTC came along. Mind you, several things we were told about S stock in initial training turned out to not quite match reality but I'll say no more as we've already drifted way off topic!
