  We present here a system with collection of random walks relaying a signal in
one dimension in the presence of delays. We are interested in the time for a
signal to travel from one end (start) to the other end (finish) of the lined
group of random walkers. The delay is introduced at the point when the signal
is transferred from each walker to the next one. It is found that there is an
optimal number of walkers for the signal to travel fastest when delays are
present. We discuss implications of this model and associated behaviors to
physical and biological systems.
