On 03.07.11, Loco No. 23427/BRC, Train No. JUC, smoked severely from SIV near ASN RRI H/S. CLI Sri D.Singh, LP Sri Rajendra Prasad-4 and ALP Sri A.K. Banerjee extinguished the fire with the help of available fire extinguisher and arranging water from nearby tap instantly and saved the loco from a major fire. For the above work showing exemplary dedication the above staff have been awarded, each ` 1000/- by DRM/ASN.

It has been felt for quite some time that all the electrical

running staff of Asansol Division should have a forum for

sharing their experiences and ideas. TRS Operation Wing of

Asansol Division has already taken a voluminous shape and is

likely to be grown further in the near future with the

electrification of sidings and mainline. The strength of Electric

Loco Pilots, Asstt. Electric Loco Pilots, Shunters and Loco

Inspectors has also increased in the recent past. Though in

other divisions the Chalak Patra is in vogue, it was

discontinued in Asansol. Now it is felt that there should be a

platform for cultivation of technical, managerial and safety

related issues. The running staff and Loco Inspectors should

participate in sharing their experiences through this quarterly

periodical. I hope this will facilitate the running staff of TRS

Operation Wing and will also help in focusing on technical and

safety related aspects of train operation.

(i) On 30.06.11, ELP(G)/UDL took charge of multiple loco no:

23499/23322/WAG-5 of train No: EC/RXL at BWN/PF. The loco No: 23322 was dead due to smoke emission from MVRH but he did not inform the same to TLC/ASN and brought the locos in that condition at ASN. The train ultimately stalled at SLS/Starter signal as single WAG-5 was unable to haul the train.As a result considerable nos of M/Exp trains lost punctuality. SF-11 was issued to LP.

(ii) On 02.07.11 Sr.ELP(G) while energizing light engine No 23074/WAG-5/ASN raised the KLK end pantograph (PT-2) without ensuring proper placement of engine under OHE as a result pantograph got entangle with OHE wire. SF-11 was issued to LP.

(iii) On 04.08.11 Sr.ELP(G) worked 63561Up ex-ASN to JSME and returned from there by 13040 Dn without charge made over and without information to TLC/ASN & PA/JSME or any competent authority. As a result 63158,63157 had to be cancelled due to non-availability of loco pilot. SF-11 was issued to LP.

(iv) On 14/15.09.2011 ELP (G)/UDL while working Train No: EC/BGB with Elect Loco No: 23465/WAG-5, and approaching the S/S of STN, DJ tripped with dropping of QOA. He failed to trouble shoot the loco properly and failed the loco instead of coming to ASN by one block. As a result train detained for 01 hours 38 minutes alongwith other two mail/Express trains in rear. This is a bad engineman ship on his part. SF-11 was issued to LP.

(v) On 26.09.2011 ELP (Goods)/ASN, B/line the loco no: 27793/WAG-7 attached with another dead loco No: 27147/WAG-7 in rear. He proceeded ex ASN Shed without coupling BP pipe in between two locos and ensuring application and releasing of brakes in dead loco. As a result abnormality was found by him after passing NMC and train stopped at RNG/H/Signal. Loco was checked at UDL and found wheel skidding which was occurred due to pushing of front loco by rear loco, having no brake, at the time of braking in front loco. This is a very bad engineman ship on part of LP. SF-11 was issued to LP.

CONTECounseling

Basic Scientific Principles A fuel cell sensor is an electrochemical device in which the substance of interest, in this case alcohol (ethanol), undergoes a chemical oxidation reaction at a catalytic electrode surface (platinum) to generate a quantitative electrical response. Whenever a molecule is oxidized it loses electrons. During the fuel cell reaction, the electrons which are lost from the alcohol molecule are transferred to the platinum electrode (the fuel cell anode). Form here they flow round the external circuit to the fuel cells counter electrode. This flow of electrons through the external circuit constitutes a measurable electric current. The more alcohol molecules that are oxidized the more electrons that are lost to the platinum surface, so the greater the current flow.

Semiconductor sensor

Fuel cell sensor

Non alcohol specific Short working life Sensor saturation Non-linear response Six monthly calibration

Alcohol specific Long working life No sensor saturation High accuracy Yearly calibration

Breathalyzer myths

There are a number of substances or techniques that can supposedly "fool" a breathalyzer (i.e., generate a lower blood alcohol content).

As per the working principle any substance interference can only cause higher absorption, not lower, the estimated blood alcohol content will be overestimated.

So the myth is NOT TRUE
