#RAILWAY #ELECTRIFICATION
HISTORY & PRESENT STATUS
Electric traction was first introduced on 3rd February’ 1925 on the then Great
Indian Peninsular Railway (GIPR) between Bombay VT to Kurla Harbour (16 Route
kilometers)...

on 1500 V DC system. It was further extended up to Igatpuri & Pune. On
BB & CI Railway (now Western Railway), the first electric train on 1500 V DC was
introduced in 1928 between Colaba & Andheri. Same success story was replicated
again between Madras Beach & Tambaram section on 15.11.1931. During preindependence period, electrification remained confined to 388 Route kilometers and
it is only in the post independence period that further electrification was taken up.
Electrification of Howrah-Burdwan section was taken up on 3000 V DC during the
first five year plan & the same was completed in 1958. Changing times and a series
of events led Indian Railways to switch over to 25 kV AC electrification; the first
section being Raj Kharswan- Dongaposi of South Eastern Railway in the year 1960.
Howrah-Burdwan of Eastern Railway & Madras Beach-Tambaram section of
Southern Railway were subsequently converted to 25 kV AC by the year 1968.
Similarly challenging task of conversion from DC to AC has been successfully
completed on 05.02.2012 on the entire Western Railway portion.
Since then there has been no looking back and Indian Railways have slowly
but steadily electrified its routes. By March 2012, electrification on Indian Railways
has been extended to 22224 RKMs which includes 25 RKMs of Kolkatta Metro. This
constitutes 34.48% of the total Railway Network and 40.27% of the BG system
respectively.

On last Monday, I had traveled from Ernakulam to Calicut from this train and see some major improvement in Electrification under sketch.
***************************************
Here is my observations:
1) Shornur – Karakkad still single line, and not doubled yet. There is no sign to electrification, Railway re announced this section, will commissioned at the end of this year.

CORE has started to installed the electric poles for different section as under;
- Pattambi - Thirunavaya section - 90 % poles are installed
- Thirnavaya - Tirur section - work is ongoing at snail pace.
- I had saw some electrical posts arrived and stored at Thirunavaya yard near Railway gate of Thirunavaya, It contains 30-40 poles.
- Also last day arrived a bacth of electric poles at Calicut.
3) CORE has done Concrete foundation for the electric poles around 80 KMS Work progress between different section as follows;
 Shornur – Karakkad section– not started yet, it will start after doubling
 Karakkad-Perasunnur-Kuttipuram section – Completed fully
 Kuttipuram-Tanur- Parappangadi-Valllikunnu - Completed fully
 Vallikunnu– Feroke - Completed Fully
 Feroke - Kallayi - Work is in progress, As of now, it reaches Nallalam Diesel plant.
 Within 2 month, it will reach Calicut Station.
4) Also Kannur -Mangalore, As of now, Concrete foundation completed till Payangadi
