SBC - Kranti Veera Sangolli Rayanna Bengaluru: Station in Garden - Dinesh Kumar

Block Limits For stations (usually class 'B') on double line sections in absolute block or automatic block territory (and usually with modified lower-quadrant, upper-quadrant, or MACL signalling) a square or rectangular yellow sign with two intersecting black diagonal stripes, and with the words 'Block Section Limit' is provided 180m in advance of the Home signal; it marks the fouling point of the rearmost trailing points connecting to the station. The acronym 'BSL' may appear instead. The legend faces the station. A single white lamp may appear within the sign through a hole in the sign above the centre.
