In Gold Class, if you&rsquore travelling alone, you&rsquore given a &lsquoroomette&rsquo, a rather snug unit that accommodates a seat that transforms into a bed at night, and a drop-down sink. Toilets and showers are at the ends of each carriage. If you&rsquore travelling as a couple, or are fortunate enough to be allotted one as a solo traveller, you get a &lsquotwinette&rsquo, and it&rsquos considerably more spacious and comfortable. This features a wide sofa-like seat that converts to two bunk beds, not unlike a first-class AC coupe on an Indian train. But that&rsquos where the similarities end. My twinette is done up in tasteful wood veneer and features a proper cupboard with a safe built in. It also comes with an en suite shower-cum-toilet that is a marvel of space management. There&rsquos also a small washbasin with hot and cold water, and a full complement of hotel-like toiletries and fresh towels secreted away in a little cabinet. My seat was magically transformed into a shockingly comfortable bed when I was away for dinner, and equally magically restored when I was away for breakfast. If you don&rsquot bother to draw the blinds, you can have a view of the starry sky as you go to sleep (and an eyeful of sun if you don&rsquot wake up early enough).
