Indian Railways :In India when there is a change of guage(eg: from broad guage to meter guage) then how are the bogies of the train changed? How is it done?
I've heard of this in Russia, but not in IndiaAll railroad rolling stock has the wheel bogies secured by a single bolster pinThis is simply a 5 to 10 pound steel pin about 16 inches long that drops through the bolster beam of the rail car in to the center of the bogie, allowing the bogie to swivelWhen a rail car is lifted up, it pulls up the bolster pin with it and the bogies stay on the trackIn Russia, at the terminals where two track guages meet, each car is lifted by an overhead lift crane and the previous guage bogies are rolled away and the new gauge bogies are rolled in and the car is lowered againIt's very time consuming and truly an expensive botherBut, that's what they do - over towards Siberia - or used to do anyway.
