Clearance Study for DFC: Guidelines for Overhead Structures and Double Stack Containers

This presentation outlines the critical clearance requirements for double stack container movements in freight corridors, specifically focusing on vertical profiles for overhead structures. It details minimum height specifications for heavy and light overhead structures, as well as contact wire clearances crucial for safe railway operations. The study references specific guidelines and letters from the Directorate, ensuring that all parameters including vertical clearances for power line crossings are comprehensively addressed. This is essential for maintaining safety and efficiency in railway transport.

  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)
