I was looking at the tube map and wondering the difference between a <b>Station</b> and an <b>Interchange Station</b>?

I would assume an &quot;interchange station&quot; is one at which you can change to one or more other Tube lines (without paying any additional fare), for (one of many) example(s), Green Park.

An interchange station should have one or two coloured bands appearing above or below the name of the station on a pamphlet or guide to show which other Tube line it connects with. If you have a map you can also see where the line bisects another at an interchange station. Usually by elevator, esculator or by simply walking across a platform you can access another line and train. If an interchange station features a National Rail symbol then you can connect with non-London Underground mainline trains.

So they are scheduled stops?

Yes. No four tracking on the Underground system means all trains stop at all stations unless closed for repair. There is a limited section on the far flung northern reaches of the Metropolitan Line where you may find fast, semi-fast and local services but I'm pretty sure that is the one exception.

For anyone who wants to see what fodderfodder is looking at, there's a nice Tube map on line at

There are actually a few more stations than henneth mentions where not all trains stop, or that aren't open all the time.

Mostly they're in places few visitors would bother with. But the (constantly updated) map Roebespierre links to shows daggers against these limited-access stations, with a list of their restrictions. Can often matter if you're staying with friends.

There are in fact several sections of 'fast/stopping' services, but you don't have to think about them as such.

Hammersmith-Acton Town is a direct run if you're on a Piccadilly Line train, with the intermediate stops served by the District Line. Ditto the Jubilee and Metropolitan lines between Finchley Road and Wembley Park.

If you are on a Tube train there are little maps everything that show the route for that Tube line.

All of the stops marked are compulsory stops unless they have little markings against them eg &quot;peak hours only&quot;

The above reads like the explanatory chapter in the Complete Rules of Mornington Crescent.

You beat me to it!

Used to live right above Mornington Crescent...fortunately while it was closed.

Surely you mean the prefatory volume to the first series of primary guidelines to major laws of the game?

As this is a general interest board rather than a Mornington Crescent specific board, I deliberately kept it vague but you are, of course right.

It does read like something out of Humbolt's Complete Rules and Guidelines.
