ICF COACHES
Introduction
An attempt for standardization of manufacturing of passenger coaches led to development of IRS design of steel body coaches. In 1954 Steel body coach design was taken from M/S Schlieren Switzerland for manufacturing of ICF Coaches at Perambur.
Initially original speed of ICF coach was 96 kmph since secondary suspension was laminated spring. The design was modified to all coil bogies with longer suspension hanger and weight transfer through side bearers, thereby enabling speed potential to 105 kmph on mainline coaches and gradually enhanced to 140 kmph for Shatabdi, Rajadhani and Janshatabdi coaches as per RDSO report No CWI Vol 1.
Initial coaches manufactured were with Vacuum brake and later modified into twin pipe graduated release air brake system - under frame mounted. Due to frequent failure of SAB and heavy vibrations of pull rod this was further modified into Bogie Mounted Brake System. Brake rigging pins were reduced from 104 Nos to 82 Nos.
Drawbar capacity is enhanced from 36t to 75t.
The codal life of ICF coaches of normal utilisation coaches is 25 years and light utilisation coaches are 40 years.
