   : The UK used several systems, and a friend of mine who traveled   
   to London   
   : in the 1970's found that there were four different electrical   
   systems in use   
   : in various parts of the city. By that time they had been   
   standardized to   
   : 240 volts 50Hz, but the older plugs and lightbulbs (different   
   ones for   
   : different systems) remained.   
      
   Hmm, surely the 1970s were a tad late for different voltages   
   (certainly for London), the national grid had been started long   
   before WW2 and was complete not long after, are you are not   
   thinking of the different designs of electrical circuits and   
   sockets in use or perhaps a different time period?   
      
   I suppose that some building with their own (derived/generated)   
   power supplies might have had (still have) 'odd' systems to suit   
   their own needs, an exception rather than the rule.
