4.5. TFTR WORK IN CVV-KI SECTION USING PQRS CRANES
CVV-KI block section is an interchange point and last block section of SC
division. Traffic block availability near the interchange point is always a
challenge.
As a part of commissioning of KI yard, existing UP line CVV-KI section is
suspended. Through cut and connection, DN traffic will be dealt on new
third line and UP traffic will be dealt on existing DN line. Thus, existing UP
line is suspended for a period of 30 days till CVV yard is commissioned.
UP/DN Location Block section Length
UP line KM 562-567 CVV-KI 5.235
