For a moment there I thought you were going to say "Charles Tyson Yerkes has been featured on this channel so often he practically has his own mustache".

Charles Tyson Yerkes Strikes again!!!

I’ve always found it ironic that the train goes from Hampstead (the deepest station) to above ground at Golders Green in one station! You can really feel the elevation travelling between them

I quite like the HampHazzard nature of this video. I'll see myself out now.

Hampstead is the second deepest station, but the deepest open to the public. The deepest is North End Station AKA Old Bull & Bush (yet another Northern Line Station named for the local pub, after Angel and Elephant & Castle, and one could argue, Kings Cross too). Whilst it has platforms, stairs, and an above ground building it's for Underground staff only. It's 221 feet deep, whilst Hampstead is just 192 feet.

"...And you can tune in again next week for more of The Charles Tyson Yerkes show, when Frank Pick falls out with Harry Beck, while Albert Stanley forms a new alliance with Charles Holden. That's all coming up in next week's exciting episode, at the same time here on..." (With apologies to all my network continuity announcer friends).

I worked on the Station for seven months in the early 90's as my first Supervisor job - it was necessary to put the lifts into service by running them without anyone in them first thing and that meant walking the damned steps for each lift......i was a LOT slimmer as a result!

I found recently there’s was a station that was meant to be deeper station than Hampstead station which never opened/completed called North End which was between Hampstead and Golders Green and you could still see the abandoned platform today.

It's a strange twist of fate that without Hampstead Tube and Yerkes' dodgy dealings, those titans of 20th century philosophy Derek and Clive would never have met.

Coincidentally both Waterloo and Hampstead are 15 stories below ground. That’s a fact. I learned it from the Internet, so it must be true.

In the mid/late 1990s I did the steps, thinking I could race my workmate who was getting the lift up.

A video with Charles Tyson Yerkes.

Could you do a dedicated video talking about how the Northern Line was funded and built?

For all those doubters on KZfaq I am now a multi-billionaire due to my successful "Yikes it's Yerkes" branded merchandise! Including Tee-shirts, socks and top hats! Why the return on my "Yerkes disposable mustache" line was enough for me to finance the Barbie movie!

You are still one of my favourites as I become increasingly picky and grumpy about what interests or amuses me. KBO.

Great film! Someone should give Yerkes his own channel...

A deep video in all sense of the word, thanks for your detailed research Jago!

Meanwhile in NYC, the deepest station on the NYC Subway system is 191st Street on the IRT Broadway-Seventh Avenue Line at 173 feet/53 m below street level, so pretty close to Hampstead! It was built by the Interborough Rapid Transit Company and opened in January 1911 as an infill station along the city's first subway line (which originally opened in 1904, though wasn't extended through 191st street until 1906 and then 242 St in 1908). At the time, the surrounding neighborhood had a lower population than other areas, so they opted not to open a station at 191st Street, but when they decided to open one, interest in nearby real estate increased. When the station opened, people avoided it due to the topography.

Sounding a little hoarse today Jago, take it easy

Jago, you'll be pleased to hear geography is no barrier to being a tube nerd. Our daughter lives in Yorkshire and has just visited us in Surrey. Finding the coach down terminated at Finchley Road, she eschewed the convenience of the Jubilee line straight to Waterloo and instead walked to Hampstead to get the northern line so she could take the steps both ways just so she could say she'd done them, before descending again to get the tube.
