In 1989, in celebration of the centenary, the Rhatian Railway remobilised three living "whitnesses" of that long forgotten epoch: the 115 year old 2-6 wet steam twin engine "Rhätia", and the two almost 100 year old 2-8 hot-steam twin engined "107" and "108". <br /> <br />More than 60 years after the disappearance of the last of their kind, the picturesque valleys of Graubuenden once again resounded the unmistakable "call" of the steam trains.
