I rode on one of the new(ish) DLR trains for the first time on sunday. Going
at full pelt from shadwell to westferry there wasn't any wobble at the
front at all. So there was a design fault with the old trains which the TfL
apologists on here constantly denied despite being asked why no other tram
system exhibited it. Either that or its magic, take your pick.

Would the old trains be suitable for the Isle of Wight?

Probably too high for the ryde tunnel as they're almost mainline height.
Also they use a different 3rd rail system.

Anyway the new(ish) trains are to expand the fleet, not to replace the
older trains which remain in service.

Though it seems every "new" train LU offers them they don't want. I think
the victoria line stock was last mooted and that was no good for some reason,
and they didn't want the 59/62 or 83 stock either. If they're only going
to accept trains that are non aluminium salt water resistant then they're
going to have to get them specially built because there arn't any tube trains
left that match that criteria.

I thought it was a wheel profile issue, of running what are effectively
trams on normal rail.

ISTR Manchester Metrolink used to have a similarly awful ride, though that
might have been because they built it on the cheap and left lots of the old
life expired track in place, particularly on the Bury line. The new builds
look very different.

Don't know. Whatever the reason the new stock has sorted it. I'm pretty
sure if it was as simple as the wheel profile they could have re-profiled
all the wheels and sorted it out years ago.

Agreed, and the new trains are susceptible to the issue as well.

Ride the new stock a bit more.

DLR rolling stock is built mainly for ATO. They can indeed run on
manual, but I do wonder how Island Line drivers would feel about not
having a separate cab. Maybe they could refit them, though?
