8. Achievements of TRD Ratlam:-

i. Electrification of Diesel Shed Track, Ratlam:-The Electrification work of diesel shed, Ratlam

amounting to 3.97 Crore was sanctioned in the material modification of RE work. HQ decided to

maintain WAG-5 class locomotives at Diesel Shed, Ratlam to improve mobility therefore contemplating

at the exigency and necessity, electrification of 2.12 TKM from Ratlam station to Diesel shed has been

carried out departmentally by TRD department of Ratlam Division. The scope of this departmental work

involved cutting & pollarding of 154 nos. trees, casting of 42 nos. foundations, loading, unloading,

erection & grouting of 36 nos. masts, 39 nos. cantilevers and 08 nos. terminations. Despite of heavy

rainfall during the foundation work, daily planning was devised and the electrification work was

completed within record time of 29 days and OHE was commissioned on 29.08.19.

ii. Replacement of bridges and provision of LHS: 23 nos. bridges have been replaced and 06 nos.

LHS have been made in Ratlam division in current financial year. Also the work of 57 nos. LHS is

under progress. TRD deptt. has imparted ample facilitation during bridge & LHS works by

deploying sufficient manpower for OHE slewing, restoration and bonding works and all the works

were completed within minimum time.

iii. Shifting of portal to facilitate the provision of new lift at Ratlam Station:One no. N-type

portal of RTM passenger yard loc. 654/41-42 was dismantled and shifted to facilitate the provision

of lift at PF no. 5 of Ratlam station. The foundation, erection, load shifting & dismantling work

were done departmentally by TRD deptt.

iv. Utilization of waste porcelain housing of interrupters at Rail Udyaan, Ratlam: 05 nos. lamp-

posts have been made by using waste porcelain housing of interrupters and provided near PF No.4

at newly developed Rail Udyaan, Ratlam. These lamp posts are being used to lighten up and

beautify the greenery during night hours by improving the aesthetics of garden.

v. Electrification of Dewas Bank Note Press Railway Siding :- Electrification of Dewas Bank

Note Press Railway Siding having 2.2 TKM has been completed by TRD department and siding

was charged with 25 KV AC on 16.03.2019. Earlier rake placement was being done with the help

of Diesel Locomotives which had to be brought at Dewas either from UJN or INDB. Now after

electrification of BNP siding, placements of rakes are being done by Electric Locomotive without

any extra crew and Loco.

vi. Provision of Availability Based Tariff meter at TSS: The work for providing ABT meters in 08

nos. TSS of MP state have been completed by TRD deptt. The scope of work covered provision

of 0.2S Class of accuracy metering CT and PTs with structures & check meters at all the TSS of

MP.

vii. Provision of traction energy management server:- In order to facilitate accurate forecasting &

scheduling of traction energy under open access regime and provide necessary data to SLDC as

per regulations, traction energy management server is being provided at RCC, Ratlam. A modified

RTU complying the requirements of new EMS has been provided at DHD/TSS on dt. 07.10.19.

viii. Removal of operational constraint from RTM yard, NAD yard & BPCL siding/MGG:

• 01 no. operating constraint was removed at Nagda yard by providing 180mtrs OHE on dead end

no. 2, which will ease and reduce time in shunting of locos while runround.

• 01 no. operating constraint removed at RTM platform no.02, line no. 11 by providing modified

cantilever arrangement on dead end, which will permit dead end to place AC locomotive.

• 01 no. operating constraint removed at BPCL siding of MGG yard by providing 9.60 mtrs OHE

from Gantry, which will ease placement of rake without guard wagon.

• Modification in existing sectioning arrangement of MGG has been done to ease the movement

of goods trains in line no. 1 & 2. Earlier elementary section of both the goods line was common

so in case of loading & unloading both lines are affected due to power block. Now after suitable

modification, entering & leaving of trains has been eased.

ix. Augmentation of Traction Transformers capacity by replacing 12.5 MVA to 30 MVA

transformers at Mohammadkhera and Sehore TSS of Ratlam division : -

12.5 MVA capacity traction transformers have been replaced & augmented by 30 MVA capacity

transformers at Mohammadkhera & Sehore TSS in Nagda-Bhopal section. TR-17 & TR-18 of

Sehore TSS and TR-15 & TR-16 of Mohammadkhera TSS.

MVA) have been departmentally replaced at Naikheri, Dahod & Nagda substation.

xi. PROVISION OF MODIFIED BENT STEADY ARM-28 nos. bent steady arm of cantilever

assembly on GDA-NAD section have been replaced by modified steady arm with drop bracket to

suit 160 KMPH speed leaving no further scope.

xii. PROVISION OF BURRIED RAIL AND EXTRA EARTHING AT SP/SSPS : - Buried rail and

extra earthing have been provided at all SWS to improve earthing system as per RDSO SMI no.

TI/MI/0032 rev-1 Dated 01.04.2014system.

xiii. REPLACEMENT OF LOW CAPACITY ISOLATORS :- Division has replaced all the 52 nos.

low capacity (850Amp) isolators of mainline by higher capacity (1600 Amp).

xiv. REPLACEMENT OF ‘G’ JUMPER 105 SQMM BY 160 SQMM : -

Division has replaced all 345 nos. G jumpers of 105 sq.mm. by 160sqmm in heavy loaded area

(Between TSS and First SSPs) to improve system reliability.

xv. REMOVAL OF CONVENTIONAL OVERLAP TYPE NEUTRAL SECTION :-

Existing eight nos. conventional overlap type neutral sections at Limkheda, Meghnagar,

Morwani & Khachrod of Rajdhani route have been removed to suit the train operations @

160 KMPH speed.

xvi. REPLACEMENT OF RUSTY CANTILEVER :-

96 nos. rusty cantilevers assembly have been replaced by new.

9. INNOVATIONS OF TRD RTM :--

(i) Online Thermo vision camera :-

For Detection & monitoring of hot spot defects of OHE with the help of On Line Thermo vision

Camera. This system can be mounted on the roof of Locomotive or Tower Wagon for detecting

Hot-spots.

(ii) Provision of Voltage sensing Device in Tower Wagon. :-

To ensure extra safety during the power block, we have developed a voltage sensing device to sense

OHE. By providing this, staff may confirm before providing discharge rod on OHE by watching this

voltage sensing device indication in tower wagon whenever OHE is ''ON or OFF''

ROOF MOUNTED

ONLINE

THERMO -VISION

CAMERA

(iii) Provision of Voltage Sensing Device in Traction substation :-

In traction substation there is no potential transformer provided in EHV (132 KV) side. In case

of failure of 132 KV supply and subsequent restoration, there is no indication of the supply

restoration unless the transformer is energized and the staff on manning duty ensures physical

humming of the transformer. To overcome this problem, the sensing device has been developed

to monitor the availability of the primary supply by the traction power controller at control center

away from the substation. Voltage sensing device can be interfaced with remote control units of

SCADA system. This facilitates the power controller to take definite prompt action in the event

of failure of 132 KV power supply. The system developed is inexpensive and requires minimum

maintenance.

(iv) Provision of contact less sensing device in lieu of potential transformer for indication purpose

at switching post :-

At UJN/SSP an induction based device has been provided in lieu of PT for catenary indication on

trial basis. As such the cost of potential transformer is saved approximate Rs. 75 thousands per AT

by provision of this arrangement.

Measures opted by TRD Ratlam

to minimize failures

Special drive was launched to check all lightening arrestors ofdivision with surge monitors. TC was also issued in this concern.

Special drive was launched for checking large span wire endingcones by binocular to avoid breakdown due to slipping off OHE.

Drive has been launched to check vulnerable & old trees to cutthem off so as to prevent them falling on OHE.

Special drive was launched for thorough examination of underframe of all tower wagons regarding attention to rust andtightness.

Catenary wires inside catenary suspension brackets are beingchecked after loosing and opening the suspension bracket so as toassure “no breakage of strands”.

Loco roof checking and pantograph inspection are being jointlydone to assure pantograph fitness.

Fortnight checking & requisite cleaning of insulators are beingensured in polluted zone.

Fitness of bonding and earthing system is being ensured in time.

Special drive was launched for checking the earth resistance &fitment of all earth electrodes of OHE & PSI installations.
