This railway-type sign commemorates a Welsh Springer Spaniel that belonged to the owner of the Mouse Boiler Works in Sheffield who built two of our locomotives.  Wakeful loved to come to Mull and when quite old and known to have a heart complaint, he cleared the complete embankment in one leap when playing with two Labrador pups who had to follow up behind, puffing and blowing.  When he eventually died his ashes were scattered around the sign.
