The Bill's London Borough of Canley is based on the real London Borough of Tower Hamlets - which I believe does contain more than one train station, certainly more than one overground station at least.
{{Ununnilium}}: I dunno if Trantor actually counts - did any of the plot actually happen there?
{{Qit el-Remel}}: If Sigil makes the list, would Shattrath City in ''WorldOfWarcraft'' also count?
AirOfMystery: How many freakin' cities does the DCU ''have''?! I mean, is it ever lampshaded, or are they fictional counterparts to real cities, or what?
