New DLR trains
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. B2003 |

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. Neil -- Neil Williams in Milton Keynes, UK. Put first name before the at to reply. |

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. B2003 |

The B07 stock were delivered in two batches between 2007 and 2010. |

I rode one there and rode one back and no hint of wobble. So either I just happened to get lucky and ride the 2 that don't have it or its been sorted. B2003 |

Obviously you're an expert so fill us in on why you can't and how Audi and Jag manage it with their aluminium bodied cars. They were designed from the start to keep out water underneath, not an issue on the underground which doesn't use salt for de-icing. I don't think there is anywhere else on the UK rail network as challenging to the undersides of rolling stock as Ryde Pier. -- Colin Rosenstiel |

There's little point anyway in debating the whys and wherefores of Victoria line stock, because SWT have said a couple of times they are penciled in for '73 stock from the Piccadilly... I did read that 67 stock was considered but ruled out because there are no cab side doors? Paul S |
