Thoughts on the Tube

Sometimes I just wonder how come a tube system can have such a good reach and sometimes such a poor reliability. Almost each day ,going to work on the capital's slowest tube line: Circle Line, I realise that all of a sudden there is a lack of trains or that a signal failure pauses the train
for 7 minutes somewhere near Sloane Square Station. On weekends things are different. Lines are closed for improvements. But I guess that London Olympics 2012 has it's say in that.

I stop now being negative and I have to reckon that the tube is even so the fastest way to go around the busy capital. From Greenwich in the South-East to Wembley in the North-West the journey is just 40 minutes and above you double deckers packed are lining together with black cabs on Oxford Street's many traffic lights. Sometimes it's also a good way to see the outside central London boroughs, because almost 50 % of it's tracks are above ground.

Will Bucharest have such a tube system in the coming 100 years?
