Yes, indeed. In any case, no metro system needs wider than standard gauge tracks. Narrow gauge, as in Japan, might be better, in fact, if the tracks have tight curves. Many Continental tram systems are metre gauge for that reason. In fact, I wonder why the DLR wasn't? A good question. Did it re-use any track on the former BR route it took over going up to Stratford? Or maybe it was cheaper to buy standard gauge kit. I don't think the original DLR took over any existing track, but the later Canning Town to Stratford section may have used some of the old NLL tracks between the new stations. But that wouldn't have affected the original decision to use standard rather than metre gauge. Given its twisty, highly graded route, and modest speeds, metre gauge tracks might well have been more appropriate. There are plenty of metre gauge railways and tramways in Europe and Asia, so standard kit should readily be available. There are no metre gauge railways of any significance in this country. The DLR uses lots of docklands abandoned railway viaducts so it was presumably thought to be simpler to stick to standard gauge which seems to handle the curves without problems. The tight curves aren't on the old railway alignments. They are on the all-new sections, or corner links between old alignments. Look for example at the complex of tracks at West India Quay or either side of South Quay. |
