MANY RESIDENTS of Kyiv, the Ukrainian capital, have grown so used to air-raid warnings that they pay little heed. They prefer to think, or pray, that the common pattern will prevail: that the city’s air-defence systems will work, more or less, or that the alerts will prove merely precautionary. But for those who do take shelter, the tunnels of the underground railway network are an obvious choice. Thanks to Chinese equipment, there is some relief to be found there during what can be a long and tedious wait for the all-clear.
