As a special New Year treat we're presenting two Cautionary Tales Shorts - which have previously only been available to paying Apple and Pushkin+ subscribers. When a Plague Struck World of Warcraft: The makers of WoW wanted to spice up the fantasy computer game by introducing a virtual disease - "Corrupted Blood". It was supposed to be a fun challenge for expert player - but the illness became a pandemic which wiped out villages, cities and then whole realms. AND Blood on the Tracks: The signalmen running a busy stretch of railroad on the Scottish border had to adhere to strict rules to prevent crashes - but did those regulations fail to take into account human nature? Despite all the logbooks, alarm bells, levers and regulations, the signalmen didn't seem to notice a packed troop train barrelling towards them.
