Saw these Non AC LHB coaches in MAS outer twice in a week. First on September 26th being shunted by TNP WDS4 19545 and all neatly lined up on Oct 5th. The rake visible in the pics had SR coaches while the one behind had ER coaches ( I am guessing this as I had seen ER coaches being shunted when I saw these for the first time). Any idea which SR train is going to use these coaches?
