Anyone been on them yet? Have they managed to solve the side to side
wobbling?

Yes, and I've been intending to but not yet got round to posting about
it (a bit like a million and one other subjects of transportational
interest in the Metropolis!).

I had one trip on a new DLR train a couple of weeks ago (during its
first week of operation) from Lewisham up to Shadwell. My impression
was certainly that it had a smoother ride, though the Train Captain -
sorry, PSA - I spoke to said he didn't think it was any better than
the older trains! I was specifically looking out for the side to side
wobble, and in my subjective judgement whilst it had not been
eliminated completely, where it was apparent it was much reduced in
comparison to the sometimes quite sharp jerking from side to side of
the older trains. Other aspects of the ride quality did feel a bit
smoother than the older trains, but not radically so.

The internal design of the new trains didn't appear to be particularly
revolutionary - the layout seemed to be pretty similar to the older
trains (if it ain't broke etc). The all glazed doors is a new look,
though there is actually part of the frame that spans the width of
each door internally which isn't particularly apparent from their
external appearance. And the internal LED signs were all green, can't
remember what colour they were externally.

All in all it felt like it was a decent train. Perhaps I need some
more experience before I can pass proper judgement on whether the
wobble has been suitably abated.

Much of it seems to have been reduced by speed restrictions at certain
places anyway.

I didn't know that. Are they temporary or permanent? (i.e. Is this
wobbling partially symptomatic of the condition of the track?)


Well, in particular I was thinking of the formerly terrifying stretch
from Mudchute to Crossharbour, which has been slower and far less
wobbly on the old trains recently, but this may be related to the
building of the new platform requiring a speed restriction.

My impression is that there are other places where the speed has been
reduced, but it's hard to be sure if there's actually a speed
restriction or what kind. Given that there's track work around West
India Quay, and platform extensions at Shadwell etc, it could be that
speed restrictions related to works happen to have reduced wobbling on
some stretches where it used to occur.
