Watford DC to Stratford or Crystal Palace

Such a connection already exists and has a couple of service trains (in the current timetable 05.58 and 06.11 leave from the low level platform (normally the bay) at Willesden Junction going to Stratford and there is an 23.56 arrival from Stratford.

The connection is the 'new line' and runs from the south end of the low level platforms to Kensal Green Junction (also known as High Level Junction); you can see it if you look here on google maps (maps.google.co.uk/maps?f=q&source=s_q&hl=en&geocode=&sll=53.800651,-4.064941&sspn=17.340293,28.344727&ie=UTF8&hq=willesden+junction&hnear=&t=h&ll=51.532502,-0.241227&spn=0.004445,0.011008&z=17), it is the track under the A404 bridge

ahhh, well in that case why don't they use it more and perhaps improve service frequency on the watford branch. surely it would also take a bit of pressure off the NNL and help when things go wrong. perhaps delays in the richmond branch or such.
I agree with Tom747 totally that they should use the Primrose Hill section and also PUT BACK PRIMROSE HILL STATION! but this seems unlikely.
Think big.

Whilst we're here how about a Richmond to Euston link? Looking at the Google maps it dosn't look like this can currently be done without bypassing Willesden.
It looks like a Clapham to Euston service would involve demolishing some graves which one would not be in favour of so lets leave that one alone.

Yes, the low-level platforms on the left with the asked for connecting line under the bridge just under A404

Actually the first two services in the morning to Startford start from Platform 1 as the units normally arrive empty from Watford.

When I was spotting at Willesden Junction in the late 1960s, we always thought that the spur was called the 'City Loop'. I think that is erroneous now? PSUL has it that the services are:


Willesden Suburban Junction - Kensal Green Junction
0558/0559 SuX Willesden Junction Low Level - Stratford
0611 SuX Willesden Junction Low Level - Stratford

plus

[Kensal Green Junction - Willesden Suburban Junction]
2312 SuX Stratford - Willesden Junction Low Level
2249 SuO Stratford - Willesden Junction Low Level

City loop or city lines? The city lines run from Kensal Jn to the WCML

No. There are the city lines, but no city lines loop.

It could have referred to when NLL trains ran to Broad Street??

lol I said that on the previous page

I think Richmond-Euston services existed in the distant past i.e. before the Tube. Now you would get between the two via Waterloo in a lot less time than via Willesden.

The LNWR Act of 1907 called for a terminal loop, of main line size tube tunnel, under Euston starting from Loundon Road (now South Hampstead) and South Hampstead tunnel is all that is left of that. The 1st world war put an end to that with the restrictions in materials and labour and the scheme was modified to the current layout and as a result was not completed until 1922.

Incidently the position at Willesden should be the Camden No,2 to Watford New Station lines are the Down & Up DC Electric (formerly Down & Up New Line). The curve from Willesden New Station to Kensal Green Junction is the Down & Up New Line (formerly Down & Up New Line Loop) and this line predates the building of the DC lines when it run to the Slow Lines and was known as the Down & Up City Loop. This is not to be confused with the current Down & Up City (formerly Down & Up City Goods Loop) which were built during the late 1800's so that the blossoming freight traffic off the North London could avoid the busy station at Willeden Junction. The building of the DC lines severed the Down & Up City Loop and the Down & Up City Goods Loop remaining the only connection to the main lines at Harlesden Jn (formerly Willesden No.6).
