The first pre trials for a single car tandem lift, of the S Stock will start this Friday at Neasden, with the full car lift set for a few weeks away, (if the new lifting equipment, and cranes measure up to the spec.)
Watch this space....

Yes. Wiggle-less one would hope.

Fascinating. Are they going for single car lifting then? The original plan I worked on was for an 8-car lift on floor mounted jacks with bogie turntables under the train and, last I heard after the rebuilding of a new lifting shop was dropped, they were going to extend the north end of the lifting shop to fit a new train's length. So how's all this going to work? Where will they get an 8-car lift and run out the bogies? Or will they have to split them into 4-car units? I could write a book on how many options I've seen over the last 10 years ;-)

That's what I thought was going to happen. It sounds very time consuming to lift each car up.

Here is a thought ? What if A Pipe line, Earth Cable, King pin, Electric Cable ETC it will only take one of these to make a big MESS on The 8 car lift ?

Multi-car lifts are common on other railways without too many problems.

Single car lift is for 'emergencies' and to cover the period until full 8 car lift is ready. That should be before routine programme lifts are due.

What are the expected maintenance periods compared with the A Stock, do you know?

I could write a book on how many options I've seen over the last 10 years ;-) Thanks for your reply, Without wishing to upset the S stock clique, and its leader, i shall answer the above points. HERE IS THE CURRENT SCHEME. 1. The new lifting shed will go ahead to the south of the old lifting shed, and will ready just before the 2012 Olympic games. So there is the problem. I f you look at the in service dates for the stock, tfl will not have its new lifting shed (which includes exam and inspection roads) built, when they are out and running. 2. Without the new shed, plan B has kicked into action. Convert the existing shed so both stocks can be lifted - the S STOCK WILL NOW HAVE TO UN - COUPLED, (no rooms for jacks in there!!) hvac will be removed etc etc. This involves new equipment, access towers, and lifting equipment, mainly because its the old shed. 3. The short shed ( 31 to 37 ) will be closed shortly, so it can be converted, in the mean time exams switch to 25/26 north ( the old lifting shed. ) As a further note, its worth pointing out, there are no maintenance staff trained on the new stock, and as for the in service date? Try the later part of May. The training has been knocked way back, ( the first course is 6/7 weeks long, so take a rough date, and look at the calendar ) furthermore the depot has been told that train two ( the train the staff need to use for training and access ) is now due in March. Now on a much happier note, i believe the pre lifting tests went very well. I am just waiting for a colleague to pass some photographs to me, and i will provide the link.

Multi-car lifts are common on other railways without too many problems. Not too many, I've seen some dodgy gearboxes on one system and water seepage into the pits of another, but you certainly can't beat a good underfloor lifting system. I once showed some of my guys some photos of the Tandem lifting cranes at Ealing and Upminster , they were shocked to know that people still lifted trains with a crane ! There's a lot of difference in the slenderness and performance of the different suppliers equipment. The current vogue is to lift slightly higher so that use can use a mobiturn on the same track and hence avoid the need for an underfloor wheel lathe.
