Also, I wonder if this new speed restriction is due to the wobbling

alarmed passengers.

Have the DLR still not worked out how to deal with that issue? I
heard it was due to the use of tram-profile wheels on mainline-profile
rails. If that is the case, can't they just progressively replace or
reprofile the wheelsets?

I heard that but I'm not convinced. You don't get the wobble on pre-
metro systems on the continent nor the manchester metrolink. I'm
pretty sure its a train design fault that no one wants to admit to. A
decent suspension and bogie system should be able to cope with hunting
especially at the pretty low speeds the DLR runs at.
