Obviously Chiltern run their trains between Harrow and Amersham and there are trains delivering new stock which are not LU trains. But if needed, could a Wrexham & Shropshire use the Met to gain access to Aylesbury? I am thinking of an occasion when their usual line through Wycombe may be blocked and wondered that if they needed to divert via Aylesbury / Princess Risborough or get to the depot at Aylesbury, would they be allowed over the Met stretch of line?

I'm sure I've seen the W&S run through Harrow when I was in the cabin - that was due to a failed train in the peak at Neasden Junction.

Trains are meant to be tripcock fitted. I don't know if they would allow non tripcock trains to be run with a second person in the cab to stop the train in the event of passing a signal at danger, as happened on the Northern tripcock saga some years ago.

We had such an occasion last Friday with a failure at Neasden Junction. The train stuck there was indeed a Wrexham and Shropshire. It was not granted permission to enter our railway as it had no tripcocks fitted and (so one of my colleagues told me) it is not gauged for running through our platforms or passing an A Stock.

Occasionally Chiltern request to divert trains via "our side." The only stock passed to run during traffic hours are classes 165/166/168 plus the Water Jetting train (former class 117) as they are tripcock fitted. They are diverted to/from Aylesbury via Princes Risborough - so each diversion is made through the driver changing ends twice. A longer process obviously, but if they are shut down on the normal route, it is still quicker than having trains stuck.
The Class 67s and the coaching stock is not passed to run beside our trains, and even if it was, it is not tripcock fitted.
The Class 66s used during engineering works are allowed onto our metals, but only within an engineering possession.

Who "owns" the lines which are shared with BR trains?
Eg - the district branch to Richmond, the Met branch to Amersham (fast) etc.
as this surely changes who allows things on them?
Also, could (theoretically) a Chiltern train end up on the Met line via Wembley Park and be able to run?

LUL own the tracks from just south of Harrow to just north of Amersham. The Richmond branch is Network Rail, as it the Bakerloo to Harrow Weald.

Aren't Class 66s limited to 20mph as they don;t have t/cocks?
Class 20 locos have run via Amersham in service, and would not have had tripcocks fitted I assume. However, the Class 20 delivery locos presumably do have them fitted now.
LT did consider, as we all know by now as I have mentioned it before, purchasing five or six BR Type 2s (Class 25) and one was trailled via HotH, including on the Uxbridge branch. However, word has it that BR wanted too much money for locos that were 'retired'.

The Wimbledon branch of the District (from halfway between Putney Bridge & East Putney to Wimbledon) is owned by LU but is signalled & maintained to NR standards. Signalling is operated by NR staff and traction current is supplied by NR, thus NR rules apply.

However, the Class 20 delivery locos presumably do have them fitted now. The 66s are limited - partly because of their non-tripcock status and partly because the area they would be operating within would be a possession. Forgot about the Class 20s, a few of which are tripcock fitted for special working use.

Also, could (theoretically) a Chiltern train end up on the Met line via Wembley Park and be able to run? Simple answer is yes - infact it has happened at least once before, with a Chiltern (probably British Rail then) train taking the route via the local lines at Watford South Junction to Harrow, and then having to reverse via Neasden depot. Every time a re-issue of the "Line of Route" regulations is due, we always request that research is done into whether the regular Chiltern stock can be passed for the local lines and to/from Neasden depot. Nobody has, as yet, stuck their neck out to give such authority. I have been on for at least 2 signal failures which would have benefitted from at least part of that route being available. Trains have passed over the routes without incident, but of course for it to happen as a "planned" event, we need the necessary documentation.

A co worker of mine tried to cut it in a few years ago when it visited the Bluebell!

We have in the past discussed which diesel locos had tripcocks fitted when new. Including from memory Classes 15 [for running on the Northern Line] and 24. I cannot recall whether any of Classes 16, 25, 31 and 20 were so equipped, for running over the Central and City Wdened Lines. Of relevance here was whether any 20s (EE Type 1) were based at Bow, Devons Road or Stratford and so equipped for running over the ELL via Liverpool Street. I am too lazy to check!

We used to meet them at Amersham, pilot them into and around Neasden Depot with a refurb, then pilot them back to Great Missenden with a non-refurb. These locos were not fitted with tripcocks.

I remember seeing one at Chalfont once. There was a brake van translator at each end! What was the route for those train once they got to Missenden?

Class 24 diesels were regular visitors to Watford Met in the 1960's In the West of Watford book by F.W. Goudie & Douglas Stuckey there is a photo of D5059 running round a goods train in the station yard in November 1966.

...and perhaps a couple of Class 66's will be so fitted, ready for the leaf fall this year?

The route north in those days was a lot easier, Aylesbury, Claydon LNE Jcn, Bletchley Flyover and then either West Coast to Crewe or onwards to Bedford and Midland to Derby.

I believe prior to the 1990s, it did not matter whether BR trains were fitted with tripcocks, as the class 115, which were used on the Chiltern Lines between 1960 and 1992 were not fitted with them.
When the first turbos came out in 1990/1, they were not fitted with tripcocks initially because they had ATP. BR tried to arrange some possessions with LU to install the system but this wasn't possible so they were all retro-fitted with tripcocks.
On a side note, Chiltern's ATP was installed at Northwood (maybe Northwood Hills?) for testing purposes to see if it would work with 4 rail track

How busy are the Met lines between Harrow on the Hill to Amersham? According to East-West Rail Consortium www.eastwestrail.org.uk/reports/They want to send 1tph Milton Keynes to London Marylebone via Bletchley, Winslow, Aylesbury and High Wycombe (88 min) Could they realistically run this via Amersham as fast non stop between HotH to Amersham?

Depends on the stock. If they hired one of the four DRS Class 20s with tripcocks and undertook gauging and clearance runs beforehand, I suspect that they might be able to get approval to run via the Met Main.

They could, but I presume the reason why they are sending it via High Wycombe is to link the three major towns of Bucks together to provide a regional service. Also it's possible that they want to slow the service down to prevent it competing with the semi-fast London Midland services starting at Milton Keynes.

The track between Swanborne and Bletchley would need to be reinstated, and replaced elsewhere for this to happen.
