Another thing I've noticed about the Northern Line as of late is that it announces the next station just as it's about to enter it. Beforehand the announcement was more in advance.

Yes I was amazed at how quick the Victoria Line trains start moving, almost the instant the doors are shut. But besides that they seem just as fast as each other. The Jubilee Line I find hits the maximum speed allowed between: London Bridge-Bermondsey Canada Water-Canary Wharf Canary Wharf-North Greenwich On the surface level I believe it's at its fastest when passing neasden depot With the victoria line the best thrashing tends to be between: Stockwell - Vauxhall Kings Cross - Highbury & Islington Finsbury Park - Seven Sisters* * - possibly the longest stretch of tunnel between two LU stations as the train is going fast on an appearantly down slope yet still takes quite a bit of time to reach Sisters. Back to the Northern Line I don't think it's quite yet up to its capable optimum speed. Certainly isn't yet on the Morden leg. I'd say Kings Cross to Caledonian Road is quite a long stretch of tunnel along with Hatton Cross to Heathrow Terminals 12&3. Terminal 4 to Terminal 1/2/3 on the loop seems longer.

The Jubilee Line ATO system is not that fast. There's always a long pause between the doors closing and the train actually moving. Compared to the Victoria Line's ATO, where the train flies out of the station the instant the doors close. I love how the doors on the Vicky Line open before the train has completely stopped. You get that on some of the older trains too. Yes I was amazed at how quick the Victoria Line trains start moving, almost the instant the doors are shut.

Weren't those Central Line trains restricted down to 40mph quite a few years back?

Apparently the 1992 stock will be getting new motors. Maybe then the speed will be increased to 100 kph again.

The Northern Line ATO is pretty rubbish IMO. Whoever designed the software seems to think the accelerator is an "on/off" switch with nothing in between. Then there is the target speed which the train tries to maintain at the expense of comfort. As a result the train will apply power for a second, reach target speed, then exceed it ever so slightly, apply brake {repeat cycle continuously}. It makes for a jarring ride when it frequently alternates between accelerating and braking. Why can they not make it as smooth as the Victoria Line system?
Oh, I'm not impressed either with the refurbished seats. Bring back the old sprung seat bases. It feels like I'm now sitting on a park bench. Though the seats are no where near as bad as the Victoria Line's which are too low to the ground, shallow and upright. Whoever designed the Victoria Lines seats clearly did not try sitting on one as a prototype.

I find the Victoria Line stock seats quite nice to be honest but I agree with the Northern Line stock seats being horrible.

I believe the difference is ride quality is down to the number of junctions and speed limits that are located along the Northern Line, opposed to the Victoria Line which has consistent fast running speed throughout except at the Northumberland Park depot. I could be wrong. I personally prefer the Northern Line in its current form, as journeys have gotten faster.

Though the seats are no where near as bad as the Victoria Line's which are too low to the ground, shallow and upright. Whoever designed the Victoria Lines seats clearly did not try sitting on one as a prototype. Many years ago I visited the mock up of the Victoria Line stock when it was at Euston, out near the bus station. I commented then, to the Line General Manager, that the seats were awful - too narrow for a fat git like me and very uncomfortable compared to the sprung seating in 67 stock. I was told that a certain Managing Director [1] had sat in the Vic Line seats and declared them satisfactory. No one dared change them after that. I have heard subsequently that once the trains went into regular service the seat design and the colouring were thought not to be the best. However we're stuck with them for decades now. I think there's been a policy decision to take out padded seat cushions because they cost money to keep "plush" because the springs get damaged and the moquette crinkles. This gets marked down in Mystery Shopper Surveys so having flat bench like seats takes those problems away. The fact the trains are uncomfortable is neither here nor there. [1] not the current MD.

Have you ever been on the Northern Line from Totteridge and Whetstone and High Barnet? If you have not, sit at the end of any carriage, you will feel something The Victoria seats are a bit hard. I used to enjoy bouncing from Kings Cross, down the hill to Seven Sisters! The Victoria line is really trying to compete with the central line in terms of the speed it approaches station!
