100Km/h certainly is fast for a metro!

Also, it's understandable that the tube has high average speed, because the average distance between stations is quite big... Less stops --> Higher average speed.

I'm pretty sure they are quite quick compared to many other underground systems. Paris will seem to take longer in a way as the stations are more closely packed so more delays.

Rome and Brussels certainly don't seem faster, but I have not been on any other tube like train systems.

Edit: whilst typing it seems my thoughts have allready been writen by others.

Paris has a dense system but RER takes care of express routes.

London's system is impressive, Id like to ride it someday and those are great photos.

Is it? I don't really know much about subway systems across the world.

I love this video as it shows the Central line going quite fast, but it's quite far outside of London here. However, if going on the Central line between Liverpool street and Stratford it can seem incredibly fast..

Love this video as well cause it shows how noisy the Victoria line is, apparently it can give you hearing problems if you travel on it everyday

As has been mentioned, the stops are generally pretty far apart in Central London (compared to Paris for example), so it follows trains have more time to accelerate.

An illustration of the frightening speed with which Central Line trains hit platforms: They are fully ATO so can brake with much less margin for error than a driver would ever dare, plus the 'hump' profile of stations (i.e. descending gradient away from platforms, ascending up to platforms) assists deceleration:

BTW I'd estimate it to be doing about 60kmh as it hits the platform

People go on about the London Underground but it's never been as bad as all that. Sure some of the deep level stations from the earlier part of twentieth century are a bit drab, but some of it's real nice to look at, if not a little old.

And also it's not stagnating, the Jubilee extension really is superb, and yeah it was over budget, but most be projects are in Britain, public and private, or a mixture of two as in this case. Overall, increased investment in the last decade has really made it cleaner, safer and minimized breakdowns.

In addition, it's quite reliable and fast, my only qualm is the constant shutting down of the metropolitan out past Finchley every weekend!

That shitty bus replacement turns the 1/2 hour journey into a 2 hour one!

That's what I'd call good customer service. No time is wasted!

How is that of the hump??
Is there a hump in the middle of the station, so that when entering the station trains go up and when leaving they go down?

Like this:..___Platform___
________/.....................\____________

Ok, shit diagram!

...So as the train enters the platform its climbing a rising gradient (aiding deceleration) and then when it departs its down a falling gradient, aiding acceleration.

The actual platform is level, the gradients are outside the station.

That's a good'un as well. I love the growl of the train before it reaches the platform.

Do you think the Victoria line will enter stations as fast when new stock comes? and the Jub and Northern, though it will probably be less noticeable because of shorter trains I spose.

That's quite a slow approach by Central Line standards... Maybe only 30mph / 50kmh.

The Victoria Line trains will no doubt enter plaforms as fast if not faster with the new stock... They already do hit platforms at a pretty frightening speed.

They'll be faster than the 92TS?!?!? Bloody hell.

And according to another forum, some of the cars for the new stock has arrived at Northumberland Park Depot.

I'm assuming it's historical reasons. When the name was thought up it was probably mostly underground, the extensions into the suburbs (then it was the middle of nowhere) where a later add-on.

I like the fact that it sets it apart from other systems across the world, most of them are called "x metro" or "y subway"

I think the term was first coined after a fashion with the formation of 'UERL' (Underground Electric Railways of London) in 1902. This was Charles Tyson Yerkes' company which initially accounted for the Piccadilly, Bakerloo and Northern (Charing Cross Branch) Lines only, which were all underground with a couple of minor exceptions (Piccadilly Line from Barons Court to Hammersmith + Lillie Bridge Depot, Northern Line at Golders Green + Depot, Bakerloo Line's London Road Depot). Before these three lines opened UERL also assumed control of the Metropolitan District Railway (later District Line), which bucked the trend by being mostly above ground. The 'Underground' branding was applied when the three Tube lines opened in the Mid-1900's.

Tubeman, do you have any maps of London's original line? As in, the first first line constructed.

After all these years, I still haven't seen it.
