:00:20. > :00:22.things are about to get even worse over the Bank Holiday weekend.
:00:23. > :00:24.In fact Network Rail says it'll be their biggest
:00:25. > :00:28.ever August Bank Holiday of engineering works.
:00:29. > :00:30.Several main London stations will be affected -
:00:31. > :00:38.No bank holiday break for these rail engineers,
:00:39. > :00:41.working to modernise the network across the capital.
:00:42. > :00:44.When it comes to the disruption to services over the next three
:00:45. > :00:48.days, it's a fairly comprehensive picture, with most of the main
:00:49. > :00:55.Except for Euston, which will be closed altogether.
:00:56. > :00:58.This is all a small price to pay for improvements
:00:59. > :01:02.that will last for decades, that's according to Network Rail.
:01:03. > :01:04.It's about increasing capacity through the centre of London,
:01:05. > :01:07.but also improving the range of destinations passengers
:01:08. > :01:11.For instance, travelling from Cambridge down to Brighton,
:01:12. > :01:15.So the range of travel opportunities will increase significantly
:01:16. > :01:20.At Wembley, fans gathering for the Rugby League Cup Final
:01:21. > :01:25.And Arsenal fans going to Liverpool on Sunday won't be
:01:26. > :01:31.But for many Londoners, it's the continued disruption
:01:32. > :01:34.into the next working week that they're really bracing
:01:35. > :01:39.They're all saying go with plan B - stay at home,
:01:40. > :01:43.But I'm not quite sure that'll happen for some people,
:01:44. > :01:45.because they have to be in and be seen.
:01:46. > :01:47.Apparently I've only got trains into Victoria,
:01:48. > :01:51.So I've got to work out how to get there.
:01:52. > :01:54.I think if it has to be done at this time of year when it's quieter
:01:55. > :01:56.than the commuter time, then so be it.
:01:57. > :02:04.There are three separate, large projects working simultaneously,
:02:05. > :02:08.so why not stagger them rather than cause so much chaos at once?
:02:09. > :02:11.The majority of work we carry out actually takes place overnight.
:02:12. > :02:16.We carry out about 15,000 projects, most of them happen overnight.
:02:17. > :02:19.But the ideal time is bank holidays, when there are fewer people
:02:20. > :02:22.travelling, and we can deliver these railway megaprojects
:02:23. > :02:25.and we can get in there and deliver larger projects.
:02:26. > :02:27.17,000 engineers will be working around the clock
:02:28. > :02:37.Well into next week, the advice is to carefully plan your journey.
:02:38. > :02:41.This weekend's Notting Hill Carnival will be one - like never before.
:02:42. > :02:45.Police say they'll have a ring of steel and concrete which they say
:02:46. > :02:47.will help "protect Carnival-goers" from the threat of a

:02:54. > :02:56.But they have come under criticism for their approach

:03:06. > :03:08.And top of the Met police's safety concerns when it comes to Carnival.
:03:09. > :03:13.It was one of several areas Scotland Yard
:03:14. > :03:16.So those coming to Carnival will see hostile vehicle mitigation.
:03:17. > :03:20.Blocks of concrete that will stop and prohibit vehicle access
:03:21. > :03:27.A familiar site at this time of year in Notting Hill,
:03:28. > :03:33.What has been a less familiar theme in the past has been

:04:07. > :04:11.of the largest event in the capital's calendar.
:04:12. > :04:14.It would be remiss of us not to be robust.
:04:15. > :04:18.We will be uncompromising on our determination
:04:19. > :04:21.to keep our communities safe and secure, and that is why
:04:22. > :04:27.we always have, at all of our major events, an intelligence led
:04:28. > :04:34.Up to 1 million people will dance through the streets
:04:35. > :04:38.The message from the Met police today was clear,
:04:39. > :04:47.It's one of the busiest motorway junctions in the country with more
:04:48. > :04:51.accidents than any other in England - But plans to improve the M25
:04:52. > :04:54.at junction 10 could threaten a number of rare trees and plants
:04:55. > :05:06.Highways England says the upgrade will make the road safer -

:05:52. > :05:54.Highways England says the strip of road in question has one

:05:58. > :06:04.I use that road everyday too, I'm also a commuter coming from London,
:06:05. > :06:09.But there is a brownfield site on the other side of the road
:06:10. > :06:11.where an extension could take place which wouldn't involve taking some
