These look like MAC Electronic Signalling Systems. After some years, on this route also ABSS(Automatic Block Signalling System) will take charge. The Electrification Works are on in full swing on a war footing. Nice to see the Wide Span OHE Side Poles on the platform areas. When is the expected date of completion ? I had heard that it's Dec, 2012 or max by March, 2013 :-)
