A home signal at Caution indicates that the train may have to stop on the line before leaving the block, or that the train has to slow down to a particular speed in order for the starter signal at the entrance to the next block to shift to Proceed.
For stations with multiple lines where a train may be received (i.e., main running line and loop lines), normally home signals are provided with route indicators ('feathers') , just before the diverging points to the various lines, to indicate for which line the points have been set for the train to be received.
