A Stock looking tatty recently

I am interested in the by-line that the A stock are the 'best trains on LU' Would you like to explain why you think that is. I think many points can be made in their favour unless you suffer from a back complaint . Before track relaying at a certain point we knew to brace ourselves for the transition from cwr to bullhead jointed track> sadly one day my partner forgot and ended up in the osteopaths. I dont hink LUL would have picked up the bill.

Having said all that we'll miss them when they've gone. The S stock seating will in no way be enough even after the extra frequency. Many times I have travelled outside the peak and the train is full by N Harrow especially during the weekend morning. Are LUL really going to give Watford more than a 10 min off peak service after 2013 when the new signalling kicks in - assuming it does?

Oh and to answer the thread-YES. The trains are looking tatty-someone paint them please!

It was even funnier when the speed limit was higher. As a kid, I used to love riding them between Finchley Road and Wembley Park - used to get thrown out of my seat if the driver was giving it some!

Yeah I read that, and the A60s used to pitch at high speed-so they had to invert the suspension on the latter cars!!

I think you'll find that the number of trains cancelled due to No OK Rolling Stock has reduced since PPP. The older Rolling Stock has been a key performer for the InfraCo's - bar the C Stock - but that is also down to issues out of the control of Metrodebt.

The A Stock fronts are looking in a terrible state now. Have Metronet given up on these in the same way LU did with the 1959/62s towards the end?

The thing is they tried to save money on the paint on the A stock by not painting them. Instead they used sticky back plastic like i used to do my books with at school, to touch up over graffiti and it did look good but some one has cocked up, cos when there was more graffiti they where meant to recover with the sticky back but instead they used the same chemicals to clean off the graffiti as the paint, but it takes the colour out of the plastic which goes white and looks rubbish

I totally agree. Considering the relative speeds the Met user does rather well. I went on a 73ts recently too, and that was dreadful (although it was virtually crush loaded!).

Having travelled on the 1938 stock on LU metals and on the IoW, it is very noticeable that track quality has a significant impact on ride quality.

I think the ride on the Central Line is quite unpleasant in the central area, especially when following another train, simply because the train seems to spend 90% of the time in either full parallel acceleration or maximum brake! The ATO doesn't seem to allow much coasting, so it seems that you are constantly being pushed or pulled.

A driver will tend to smooth out the acceleration and braking by coasting more and not racing up to the next red signal, judging a steady speed that is likely to mean arriving at the next signal around the time that it is likely to clear.

Isn't part of the idea of ATO that the acceleration / braking curve is as steep as possible - by constantly performing simple physics calculations, the train can brake far sharper than any T/Op would dare, to safely stop.

Yes. The trouble with that is it's pointless if you know you are going to follow the train ahead for the next 12 stations! You may as well ease up a bit, have a smoother ride and get to the destination just as quickly.

However, it's that very aggresiveness of the Central Line which allows headways to decrease to as little as 90 seconds without blocking back.

About time the English use what they gave to Hong Kong? A smooth variable ATO which doesn't rely on one fixed speed algorithm!

You could compare A stock to C stock on the top half of the Circle, and then compare C stock to D stock on the Wimbledon branch of the District.
