Tony Posted August 12, 2019 Report Share Posted August 12, 2019 Looking at the front there's been an impact that i get but if de-railed how has the rear bogies been dislodged and be in the same direction as the front? Quote Link to comment Share on other sites More sharing options...
CP09 Posted August 13, 2019 Report Share Posted August 13, 2019 IF you look at the bogey furthest away, it's actually created deep scores in the tarmac surface. It's not on a set of rails. The front bogey is located on rails. Assume the tramcar was travelling left to right, something else was moving from back to front (as we see the picture). That would :- a) damage the front left of the tram (as photo) b) impart a torque on the tram to turn the front towards us and the rear away (clockwise from the top) Let's assume the driver hit the emergency brakes, than the weight transfer would be rear to front, an impact would also raise the rear of the tram, allowing the wheels to jump the rails. Once the wheels are free of the rails, the bogey will rotate to the least resistance - i.e parallel to the direction of travel. It also looks like the bogeys have been displaced from their normal positions (the trams leaning)... Quote Link to comment Share on other sites More sharing options...
Tony Posted August 13, 2019 Author Report Share Posted August 13, 2019 Good analogy..... You would expect a severe impact to make the tram rotate like that and tear both sets of wheels away. Quote Link to comment Share on other sites More sharing options...
SMARTLY Posted August 13, 2019 Report Share Posted August 13, 2019 Think it might have hit a bend / points type thing on a railway that threw it off the track? Quote Link to comment Share on other sites More sharing options...
Tony Posted August 14, 2019 Author Report Share Posted August 14, 2019 That would add force directly to the wheels so it makes sense. Quote Link to comment Share on other sites More sharing options...
