Long DLR Train
This morning I've seen a three-unit train running on the DLR, with the
designation "Special", in between other services. (Am I the only one having trouble perceiving the "articulated vehicles" as anything other than units of two coaches?) Presumably it is some kind of test run. The one I saw was made up of the new units. |

I would have been interested to see where it stopped at the stations which will be using SDO. Most stopping points have been shifted to where the front of the train will always end up in future, ie the same place regardless of train length. Now it occurs to me that, with phased introduction, the SDO stations will have to have different stopping points for different lengths of train. |

I'm wondering about whether the "light" railway designation still means anything. The 3-car DLR train is about 84m long, compared to about 96m for a 6-car C stock train. But the 3-car DLR trains will be longer than the 80m Class 378 4-car trains. However, the DLR trains are narrower (2.65m vs 2.8m for the 378 and 2.92m for the C stock) |

More info here at the "DLR Press Room": http://pressroom.dlr.co.uk/news/details.asp?id=220 With the exact same press release available at the main TfL "New centre": http://www.tfl.gov.uk/corporate/medi...tre/14063.aspx Have the DLR actually got their own PR operation or not? The contact details shown at the end of the press release on the DLR site are the main TfL press office, but that doesn't in and of itself mean anything. Plus I thought that DLR did have its own people (and they were DLRL as opposed to Serco Docklands). Anyhow, that's all by the by. I see that the Director of DLR, Jonathan Fox, says "[...] I'm confident our Bank passengers will really notice the difference at the new and improved platforms". They weren't all that scrubby were they - they're pretty new, after all! |

DW- Personal observation made me think that the middle one looked long, but I put it down to small wheels. I thought that the end ones were the same. Personal observation of the older units was that the bogies weren't as long. Then I'm sure I saw another diagram, I think it was the ones they are using to show where to get off at SDO stations, which pictured a new unit and showed the middle bogie as longer than the end ones. This is what I need to check on, but the chances of standing on the opposite platform from a train of new units (the only way to see the wheels) are relatively rare. |

I doubt the articulation would work with separate bogies and still be able to run around the sharp curves. There's absolutely no doubt about them having a middle bogie at the articulated point (ie three bogies per "vehicle"). The only question in my mind now is whether they are a different length of bogie from the earlier units. My impression was that they are, but I'm wondering if it's some kind of illusion. |

They weren't all that scrubby were they - they're pretty new, after all! They've got benches now (on both platforms). If they weren't added in the last few weeks, they were certainly added relatively recently. The lack of anywhere to sit made Bank particularly uncivilised, I thought. |

But surely a tram is still an LRV, even if it's running on standard track, as happens on at least some parts of Manchester Metrolink, Tyne & Wear Metro and Croydon Tramlink? And does the DLR use lightweight rails? |

I think it's probably an illusion caused by the smallness of the wheels. Actually I could be confused. I think the new units (supposedly illustrated in the diagrams) have longer bogies, or possibly just a longer middle bogie. I hadn't heard that the new bogies were longer. I wonder why they'd do that, on units that have to get round very tight curves? Conversely, in the artist's impression you posted, all four (sic) bogies look too short. But I'm guessing that was just the artist making that bit up, not thinking anyone was particularly interesting in the wheels. I also wonder if the floors aren't too low as well in that sketch? I will have to start paying more attention, and maybe take a snap. Further posts may be from Belmarsh. Yes please, of the elusive latest models, B07/09 ... which may indeed have 4 bogies ... we shall see. The picture he http://www.railfaneurope.net/pix/gb/...u/B07/a1n-dlr- snow-jp.jpg shows the B07 units as only having a single middle bogie. You can see the spots where the wheels are behind the current rail at the front, middle and back of the unit. I doubt the articulation would work with separate bogies and still be able to run around the sharp curves. There's absolutely no doubt about them having a middle bogie at the articulated point (ie three bogies per "vehicle"). The only question in my mind now is whether they are a different length of bogie from the earlier units. My impression was that they are, but I'm wondering if it's some kind of illusion. Well I looked at the image upthread, and page zoomed it up the magnification - which becomes pixellated. It's very hard to see, but from the positions of underfloor equipment, ISTM that there isn't room for separate bogies under each car at the "joint". Thanks to those who've been looking and shooting.

I've always assumed the difference to be in the weight of the running rail. -- Clive Nah, many "light rail" systems run on exactly the same track as the railway line they replaced. Light rail refers to a combination of: - lighter specification for equipment (end loading, coupling stress, etc); - lighter systems of control, in the sense of either not a comprehensive external safeworking system; or a signalling system limited to vehicles of a common performance and specification standard; - lighter "greenfields" infrastructure where only the LR equipment is to operate (T&W might still have freight, they did in the early stages). - lighter, in the sense of smaller, trains. Perhaps I've put enough into the thread to keep the wheels turning? DW downunder |

Just to follow up after using Bank a couple of times this week, another distinct improvement is that the trains no longer seem to jerk violently almost to a halt half way out of the platform and make people fall over. |
