We always know when summer is on its way on the Isle of Man, because the railways tart up the trains and trams and the horses start getting their summer shoes on.  We are so lucky to still have three, yes three different types of heritage railway, and this summer visitors are coming over to see and travel on those old railways.  It will be wonderful to see the steam trains puffing across the landscape, but best of all is the horses tripping up and down the promenade.
