	i didnt thought that a loco is this much complicated.great set of pics and detailing...would like to know more about the tech aspects...so expecting more from u Khalid sir... Posted by Deepak Murali on 2007 Dec 11 15:49:12 +0000
	In fact its the same with the Control Circuit Breaker to the right.Only one pole is utilised.This is probably the safer option to keep the negative permanently grounded to the loco frame to prevent any unwanted potential from appearing on the loco frame.Inspite of needing only one pole,the more reliable MCCB has been used probably because it can interrupt heavy DC currents safely and also has intelligent tripping options unlike the simpler Miniature Circuit Breaker(MCB)fitted in the top row.

	In these four wheeler oil tankers,there are two versions-one with screw coupling and the other with CBC.The Railways do not allow the direct coupling of these types of wagons.Instead a bogie wagon is marshalled between these two types of wagons to maintain stability.This bogie wagon has the two different types of couplings at its ends.

	Good coverage on technical aspects of WAG9. Similar key interlock is also used in motor-coaches of AC/DC EMUs in Mumbai. http://tinyurl.com/3435l9 Posted by Prakash Tendulkar on 2007 Dec 10 18:07:31 +0000
