1.	In this form of track, the rails are welded together by utilising flash butt welding to form one continuous rail that may be several kilometres long, this type of rail is called __________(a) Continuous jointed rail(b) Merged rail(c) Continuous welded rail(d) Continuous welded railThis question was addressed to me during an internship interview.I need to ask this question from Railway Line in division Road Estimating, Sanitary and Water Supply Work of Civil Engineering Drawing
Answer» Right choice is (c) Continuous WELDED rail To explain I would say: In this form of track, the rails are welded together by utilising flash butt WELDING to form one continuous rail that may be several kilometres LONG. Because there are few joints, this form of track is very strong, gives a smooth RIDE, and needs less maintenance; trains can travel on it at higher speeds and with less friction. Welded rails are more expensive to lay than jointed tracks, but have much lower maintenance costs.
