Many years ago back in the early 2000s, I recall there being engineering works happening a number of times which shut the local lines between Harrow and Moor park (I think the Watford service ran using the north curve to Amersham) but the Fast lines remained open as usual. I remember travelling between Harrow and Moor park watching all the engineering trains and workmen occupying the line.
I have not seen such a closure since these days as its often the entire section between Wembley and moor park which is closed. It was rather handy having one pair of lines open whilst the other was closed for works. Why doesnt this happen anymore?

Simple answer, health & safety of the track workers - usually traction current related issues.
(remember 1981/2 when Hanger Lane bridge D29 was replaced, District ran a service to/from Ealing Common station, with the work going on a few hundred yards ahead. Bridge replacement work Ravenscourt Park, with single-line working trains running past the worksite)

I wish I was around in the 80s to remember such works!
Is H+S a reason for not leaving one pair of lines open on the met? There seems to be adequate spacing between the locals and the fasts. Also remember, we are only talking the period roughly 2000-2005 which isnt actually that long ago. Have regulations changed that much since then?

District and c2c do run alongside each other when there's minor work going on that closes the other line, but its certainly been the case more recently that major works with a busy worksite (ie, lots of people as opposed to a handful) will lead to a simultaneous closure of both lines.
I would imagine its not just about people and their proximity to moving trains though. If the nature of the work requires cranes for example, room has to allowed for them swing around. Then there's storage of materials being installed or removed - space might be needed adjacent to the worksite to facilitate. Similarly with tools and plant - an adjacent track might be needed to store these items when they're not being used.

It's also worth remembering that there have been a number of track-worker injuries and fatalities on NR in recent years, indeed so many the RAIB launched a class investigation into their safety. Although LU is not NR they obviously pay attention to changes in safety measures on the other network - nobody wants to harm track workers.

Also not forgetting that they're probably installing signalling up to Moor Park for both lines

There are some Network Rail engineering vehicles without a floor that enable track work to be carried out whilst trains are running on an adjacent line.
In this way the workers are protected working inside the vehicle and they can't step out of the safe zone.

Today being a prime example, met shut from Northwood to Wembley yet Chiltern cannot go past amersham. Are the fast lines due for work this weekend as well?
I live close to the 4 track section between moor park and harrow and cannot see anything work wise going on?
On a historic note: were there ever times where engineering works closed the fast lines but not the slow? How did services operate then?

The work going on the Metropolitan Line this weekend of 16/17 October 2021 is nothing to do with the tracks . It’s signalling work going on at Harrow on the Hill, as the work has to be carried out with no trains running through all lines including the up and down service from Marylebone to Amersham. |

On a historic note: were there ever times where engineering works closed the fast lines but not the slow? How did services operate then? I recall the Fast lines being closed for two weeks in August 1986 (16th-30th) for track relaying. The normal Met WTT operated with little variation except of course with the fast Amersham and fast peak Chesham service diverted over the Local lines. LMR shuttles were operated between Aylesbury and Amersham and Harrow and Marylebone. The TTN (122/86) is currently available for purchase on ebay for little cost if you wish to make a closer study of the service operated. Passenger numbers were obviously reduced given it was peak summer holiday time and passenger numbers at the time were generally lower than the numbers we were familiar with on the Met pre-covid. |
