trail able point machines
Dear all,
Hi I am Jayanth tejasvy from India, I have only recently become a rail enthusiast ( due to my job). I am a S&T engineer by profession. Recently many metros have been cropping up in India. In the BOQs, the client mention TRIAL ABLE & NON TRAILABLE point machines. I would be highly obligated if someone can tell me the difference between the two. I know that the conventional Indian rails use non trailable point machines but i cant understand the difference between the two. Kindly help out.
