  1. CLEARANCE STUDY FOR DFC FOR TRACTION OVERHEAD INSTALLATIONS. PRESENTATION BY RE DIRECTORATE

  2. POLICY GUIDELINES ISSUED FOR DOUBLE STACK CONTAINERS SALIENT PARAMETERS INVOLVED MINIMUM HEIGHT OF HEAVY /LIGHT OVERLINE STRUCTURE MINIMUM HEIGHT OF CONTACT WIRE POWER LINE CROSSINGS

  3. DOUBLE STACK CONTAINER MOVEMENT ON FREIGHT CORRIDOR UNDER WIRE (Vertical Profile Scheduling) Min. Fixed Dim. = 7760/8140 mm 250/630mm Height of CAT = 7507 mm { Height of CONT = 7079 mm 270 mm Max. Mov. Dim. = 6809 mm RAIL LEVEL = 0 mm

  4. COMPARATIVE STRUCTURES

  5. MINIMUM HEIGHT OF OVERLINE STRUCTURE • LETTER NO. 2006/RE/161/3 DATED 19/5/06 • HEAVY OVERHEAD STRUCTURE ie ROB – 7760mm BASIS: HEIGHT OF CONTACT WIRE - 6809+250+20 = 7079 mm HEIGHT OF CATENARY - 7079+11+417 = 7507 mm MIN.HEIGHT OF HEAVY OVERLINE STRUCTURE – 7507+250=7757 SAY 7760 mm

  6. MINIMUM VERTICAL CLEARANCE OF LIGHT OVERHEAD STRUCTURE • REF. LETTER NO. 2006/RE/161/3 DATED 19/5/06( REF. ITEM NO. 10(iii)(a) OF REV SOD 2004) • MIN HEIGHT OF LIGHT OVERLINE STRUCTURE eg FOB = 8140 • BASIS: • HEIGHT OF LIGHT STRUCTURE = 7760+380 = 8140mm

  7. MINIMUM HEIGHT OF CONTACT WIRE • BASIS: • MINIMUM HEIGHT OF DOUBLE STACK CONTAINOR LOADED ON FLAT WAGON - 6809 mm LONG TIME CLEARANCE - 250 mm ALLOWANCE FOR TRACK RAISING - 20 mm 7079 mm

  8. POWER LINE CROSSINGS • LETTER NO. 2006/RE/161/1 PT. III DATED 19.05.06 – STIPULATES VERTICAL CLEARANCES FOR POWER LINE CROSSINGS OF RAILWAY TRACKS

  9. THANK YOU

  10. DOES IT EXIST ANYWHERE ELSE ? • CHINA • Shanghai – Kunminng Corridor • Hangzhou – Zhuzhou section • (Liujhan-Jhegan sub-section) ( 2nd National Project)
