However, The Guardian described the show as “fantastically dreadful,” giving the show two stars instead.

Radio Times also offered two stars but the Daily Mail said it was worth going “along for the ride,” giving the show four stars in its review while the Times said the drama was "barely staying on the rails".

Is the show based on a real train?

The story is set on the fictional Heart of Britain sleeper train although the Caledonian Sleeper does allow people to travel between Scotland and London overnight.
