Welcome to Amersham station. In Zone 9 at the end of the Metropolitan line, we kick off here in this new series, ticking off all the stations at the ends of the lines on Tube Map
You don't just walk into Morden - you take the tube there. It's End of the Line Episode 3, and we're down in Zone 4 in South London at the end of the Nothern Line.
Back to North London we go. And a train up to Zone 5 at the top of the Piccadlly line - how DID Cockfosters get its name? And how the heck does Charles Holden make stations made just out of concrete look so good? Let's go for an explore.
Out to East London we go, to the extremity that is Upminster at the end of the District Line. It's in Zone 6 and shares the station with National Rail C2C services, but have you ever been? No? That's OK i've been for you.
Back to the other end of the Piccadilly to Uxbridge, which is also a Metropolitan line station. Is Uxbridge the most architecturally stunning station on the network? Let's go to Zone 6 again and find out.
