A drink common among the dodgier elements of the Cape Town population.
One makes a
blue train by filtering methylated spirits through a loaf of bread in order to remove the bitter-tasting purple dye (In South Africa, the dye is mandatory in order to prevent it'
s use as a beverage). Since only the dye is removed, not the kerosene, methanol, isopropanol etc, it gets you smashed off your head, but may cause vomiting, headaches, seizures, blindness and/or
death.
It is called
blue train because the thoroughly dyed loaf resembles the
Blue Train, an ultra-luxury overnight passenger train between Joburg and Cape Town.
