25 KV Electric Traction on SER

1. 25 kV AC TRACTION on INDIAN RAILWAYS:

Chakradharpur Division of South Eastern Railway has got the distinction of introduction of

first 25 KV electric traction system in Indian Railways.

Commissioning of first Transformer and

Circuit Breaker at Kendposi

It was first introduced in Kendposi-Rajkharswan section of Chakradharpur division with the

technical assistance of SNCF (Societenationale des chemins de ferFrancais)

OHE was charged with 25 kV AC supply on 15th Dec‟1959.

The inaugural trial run took place in presence of AICCF officials and Sri. K S SambhaMurty,

then DEE/TRD/CKP on 15th Dec‟1959.

Electric loco sheds of South Eastern Railway with present holding of 75 and 150 Electric

locomotives respectively. As these sheds no more hold any Diesel locomotives so their names

5.5 ELS/TATA has become the first shed of SER to home 100% three-phase locomotives.

5.6 On Load Testing Facility for Hotel Load Converter developed by ELS/SRC & TATA:

ELS/Santragachi& TATA have developed an “On

load testing facility for Hotel Load Converter”

during 20-21. It helps in identifying defect, if any, in

the hotel load converter of the loco in shed itself. This

setup has been built up completely in-house by the

sheds using a released 60 KVA TFP of LHB coach.

5.7 Commissioning of High-end Electronics Testing Setup for M/S Medha& M/S BHEL make

Propulsion Systems at ELS/TATA:

Unique testing facilities have been commissioned at ELS/TATA for Medhamake (Version-II) &

M/S BHEL make Propulsion Systems of three-phase locos. These are the first of their type

on Indian Railways. The systems are capable of carrying out functional tests of various cards

of Propulsion Systems. It would be very useful in testing problematic / doubtful cards in

Electronics lab and will avoid troubleshooting by trial and error on locomotives.

Medha Make Test Rig (Version II) BHEL Make Test Rig

5.8 Conversion of WAG9 Bogie to Conventional Brake Rigging by KGP Workshop:

At KGP Workshop TBU/PBU to conventional brake rigging modification was carried out by

Bogie Repairs Shop & fitment of brake riggings, pneumatic pipelines, conventional handbrake

and footsteps by ERS-POH shop. Total 8 bogies were modified in 2020-21.

Unmodified bogie of WAG9 Modified bogie of WAG9

5.9 Modification of Pneumatic Pipe Line in FB Cubical:

A number of three phase locomotives have failed due to “Harmonic Filter Contactor” stuck up

“Harmonic Filter” isolated. It was found that in FB Panel ferrule of thermoplastic air tube get

dislocated due to improper griping.

To get rid of this problem, SER carried out an in-house modification by providing copper pipe

(10 mm dia) in place of thermoplastic type flexible pneumatic pipe. This said modification has

been carried out in 281 locos so far.

5.10 Modification in Pneumatic Circuit of VCB:

Ingress of moisture in VCB through its pneumatic circuit has been

a troublesome area. It hampered the functioning of VCB. SER has

carried out in-house modification in 46 Locos by providing an Air

Dryer in the pneumatic circuit of VCB so that moisture-free air may

be fed to VCB.

5.11 E70 Electronic Card Test Facility at ELS/TATA:

Brake system of three phase loco has pneumatics as well as electronics. So far sheds had test

setup for pneumatics only, so the electronic cards were being troubleshooted by trial and error.

ELS/TATA has developed a unique test set up for testing of various cards of E70 brake system

by in house efforts. The power supply cards are tested on load on this bench and

measurements are carried out at critical test points to ascertain health of the electronics.

Complete Setup of PSU Card

5.12 Consist Operation of WAP4 Locomotives by ELS/SRC:

ELS/SRC is entirely a coaching loco shed, maintaining 85 coaching electric locomotives (WAP4: 35 and WAP7: 50) and 18 Diesels locomotives. Due to COVID-19 pandemic situation; service of many Mail/Express and Passenger trains was suspended as a result some of the coaching locomotives had become idle.

ELS/SRC has made 4 CONSISTs (12 WAP4 locomotives) which are under trial usage over SER. Those are being used to haul fully loaded Goods traffic over graded sections of SER.

5.13 ELS/TATA converted condemned WAM4

loco no. 21393 to battery operated dual mode

shunting loco for shunting within shed at

restricted speed of 10 kmph only.

counselling rooms of important Lobbies of

CKP Division. This contains various items

including GyanKunj. Crew can test

themselves on both safety and technical

subjects. This is available in both online

and offline mode.

5.15 By better coordination and monitoring, Divisions controlled accrual of overtime of crew to

34,932 hours during 20-21 compared to 9,60,309 hours in 19-20. It would not be out of place

to mention that on an average 971.3 T.O.s per fortnight were served per day in 20-21

compared to 898.1 in 19-20 i.e NIL O.T despite higher T.O.

5.16 During 20-21, “Trip Schedule” of record 3532 (SER - 2480, FR - 1052) Coachingand 1925

(SER - 699, FR - 1226) Goods locos was carried out by SER.
