The subway operators in Berlin have decided for these long trains beacuse the manual labour and logistics needed to extend or shorten trains during the day is more expensive than just letting them roll.
Berlin/Germany had a tube based system for letters and postcards that extended to 400km in 1940.
It connected 79 post offices in the city and transported 8 million mailings yearly.
Destroyed in WW2 it was partly reconstructed and used up until 1986.

I am using a standard AVM Fritz!Box that includes IPv6 firmware with tunneling support: http://avm.de/en/Produkte/FRITZBox/FRITZ_Box_Fon_WLAN_7270/index.php
I am missing a question and an answer: Why is IPv6 autoconf missing such basic features as providing information about DNS servers?
Or the other way round: why did nobody think about central management stuff that DHCPv4 provides in corporate networks? DHCPv6 is nowhere even barely usable.
