ha, that's not a good thing. this is a toy junk train, were this a grainer or coal or tanker train the mass would push this end stop for several kilometers or bust the head of the rail off and thus eliminating the stop completely. less than 100nm of clamping force to the rail is preferred and more slide is required. this stop is okay for low speed yard work at end of rails. however this wouldn't stop a runaway train before it derails. also if these were longer trains the 100+nm of clamping force would cause the other trucksets further back to jump the tracks and accordion the remainder of the train in a very bad wreck. such a thing as stopping too much weight too fast weakest link in the chain breaking law of motion going on here. lifting the ties out of the ballast is very bad it means you've put a hill in the rails that is not safe to run over any more at over 5kmph as it could cause a derailment either in a tall car sway if the hill is not perfectly parallel. also that the ties are not properly seated to the base of the ground and can also sway unevenly not in parallel and with the 10,000+tons to 80,000 ton loads if a rail gets more than 3º out of vertical alignment it is subject to the pressure of the weight overhead just force laying it over on it's sides as the wheels flex pressure the rail over and that's just one wheel, in a train consist of 100-240 cars x4 wheel sets that's 200 to 480 (400-960) times just one wheel can force this to happen. how many times can you hit a nail on the head before it breaks? well every joint is the nailhead as well as every meter of rail that is out of vertical alignment. it's just a matter of time after that. an E stop such as this would require that MoW crews must inspect and retamp and realign that entire section of rail block before any further rail traffic could be allowed over it due to this 'slight' damage. bending rail vertically this much this fast would have long term effect i would logically think. it's the best way i know to break metal apart by hand since rail is designed to bend side to side quite a bit.

You should try to use the impact dampeners as hydraulic master cylinder and replace the shoes by calipers with brake pads. So the more the train pushes,the more the system is clamping the strucure on the rails. You can use a pressure limiter and even more fun,an hydraulic accumulator to have a smooth progressive rising braking force with adjustable reaction delay. Now you can send me a check if you want.

@SandyWatson456 жыл бұрын
The braking force is applied and controlled by the friction elements which are attached around the rail head and fitted under and in some cases behind the End Stop. The friction elements are not attached to the End Stop frame and rather loose in pockets under the frame. The anti-lifting clamps at the front of the End Stop which prevent the End Stop from leaving the track are essentially loose as to not provide a great deal of extra braking force. The anti-lifting clamps are standard parts designed to fit around a number of different rail profiles, hence a degree of lifting upon impact.
