This week I have been travelling from London Marylebone to Aylesbury and for for part of the journey (mainly after Amersham I think) it would seem that the Chiltern services run on the same track as the Metropolitan line services. Am I right?

I'm only curious because I imagine only one organisation can be responsible for operational aspects such as signalling.

Harrow on the Hill to Amersham - LU don't go beyond there.

LU responsible for track & signals between those.

...with (IIRC) the Chiltern sets fitted with trainstops to work with the LUL signalling systems.

Likewise Richmond to Gunnersbury and the odd ECS or late night train between East Putney and Wimbledon

North of Queens Park the Bakerloo also runs on NR infrastructure.

The District between Wimbledon and East Putney (mentioned above) is unusual in that although it was sold to LU at privatisation, but is still maintained and operated (signalled) by NR staff under a long term contract.   This is probably why mainline stock using the line is not tripcock fitted and does not use the trainstops, historically speaking it is LU that are the visitors, and they do use trainstops.

Bakerloo from Queens Park to Harrow & Wealdstone is shared with London Overground heavy rail services between Euston and Watford.

Indeed not, through the District Line used to go to Aylesbury and beyond to Verney Junction & Brill until the 1930s.

Yes of course.  My mistake.  Never operated by tube trains as such as they were steam hauled beyond Rickmansworth.

What are trainstops and tripcocks?

Also, what about places where trams and 'full size' trains run on the same track?

What are trainstops and tripcocks?

A device which automatically applies the brakes if a train passes a signal at danger (and I believe are also used in a speed control role on approaches to junctions), and also used on the approach to a terminus to ensure that trains will not hit headwalls or buffer stops at speed.

More in-depth description and some pics on Wikipedia:

Are there any in the UK?  I understood there's an issue with robustness / crumple zones of a tram when in collision with a train ... I'm thinking Croydon, Nottingham, Dublin, Birmingham, Manchester, Seaton, Blackpool, Edinburgh, Sheffield and can't think of shared tracks at all. Always kick the trains off when trams come along.
