5.0Achievements of SER during 2020-21:5.1 During 2020-21, 132 (SRC - 2, TATA - 24, BNDM - 46, BKSC - 30 & ROU - 30) newlocomotives have been commissioned at SER. With this, total holding of electric loco in SERhas become 952 (534 - three-phase) which is highest on Indian Railway.5.2 Diesel loco shed/Bokaro and Diesel loco shed/KGP have become fully operational 6th and 7thElectric loco sheds of South Eastern Railway with present holding of 75 and 150 Electriclocomotives respectively. As these sheds no more hold any Diesel locomotives so their nameshave been changed to Electric loco shed/Ispatnagar (ELIN) and Electric loco shed/KGP (ELKP)respectively from 05.01.2021 with the approval of GM/SER.Infrastructure of ELS/Ispatnagar for Maintaining Electric Locomotives:MVMT Test StandMVSL / MVSI Test StandTM Test MachineEPC Test StandPressure switch Test StandFlasher Light Test BenchSMGR Test StandPHGR Test StandPantograph Test StandTraction Motor carbon brushholder pressure test standVCD test standMV drop test-stand for line contactorsand drumcontactors

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 “Onload testing facility for Hotel Load Converter”during 20-21. It helps in identifying defect, if any, inthe hotel load converter of the loco in shed itself. Thissetup has been built up completely in-house by thesheds 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 makePropulsion 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 typeon Indian Railways. The systems are capable of carrying out functional tests of various cardsof Propulsion Systems. It would be very useful in testing problematic / doubtful cards inElectronics 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 byBogie Repairs Shop & fitment of brake riggings, pneumatic pipelines, conventional handbrakeand footsteps by ERS-POH shop. Total 8 bogies were modified in 2020-21.Unmodified bogie of WAG9Modified bogie of WAG95.9 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 getdislocated 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 hasbeen 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 beena troublesome area. It hampered the functioning of VCB. SER hascarried out in-house modification in 46 Locos by providing an AirDryer in the pneumatic circuit of VCB so that moisture-free air maybe 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 testsetup 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 systemby in house efforts. The power supply cards are tested on load on this bench andmeasurements are carried out at critical test points to ascertain health of the electronics.
