Cups and Saucers have been removed from National Express East Coast services due to complaints by some passengers in First Class that the noise of spoons against cups whilst the train was in motion caused an annoying rattling!
The first cup and saucer appeared on a British train on October 18th 1879, on a trial run of a dining car by Great Northern Railway between London and Peterborough.
They have now been replaced by china mugs which have undergone rigorous testing. These are only available to first class passengers, those in standard class will continue to be given disposable containers.
