At a society I am a member of, we used to have a traverser back in the 1980s. A girl fell off a train one day onto the traversers concrete pad and broke her arm (so I am told), so they got rid of the traverser, and installed a lifting and rotating turntable. Unfortunately in the 1990's whilst lowering the turntable, the owner of one locomotive ended up with two finger crushed beyond repair, and lost the fingers. (Also I'd highlight that unless the centre of the locomotives mass is in the centre of the turntable and the locomotive is rigid - neither of which is the case for a tender engine, then a turntable which jams suddenly will likely have the same effect of throwing the locomotive off.) So they got rid of the turntable and we now have a traverser again, though now in the monitored station area, rather than in the high speed section of the track. Now it is highlighted by this accident, it is easy to think of seeing many traversers 'wizzed' up and down at a speed that if they jammed (on a stone say) they would throw the locomotive off, and I suspect your fellow member Barrie may well have been moving the traverser up and down at the same speed that a great many others do. I don't think I have ever seen a traverser structure with anything to prevent a loco falling off. All the best, Rich. MODEL ENGINEERING DISCUSSION LIST.
