Its apparently 10cm wider than the maximum network rail loading gauge (according to an article I read in Rail today)= so will they be able to move it by rail over some specially cleared routes o= r will it have to go by road? Ah, but, in kinematic envelope terms the vehicles are relatively short (16m according to wackyp=E6dia) so the throw on curves would not be as substantial as an equiv. 20m carriage. That also depends on the position of the main pin on the bogie and the corresponding pivot point on the carriage rather than just the vehicle length. IIRC modern carriages (Mk3 etc.) are in any case tapered to compensate for their length and thus have a smaller swept path on the _outside_ of a smallest radius curve than A stock. I always thought 2.85 (ish) was the absolute maximum width no matter what the length of the carraiges. Is this not the case? You don't mind denting them so much on the way out. |
