Docklands Light Railway

From Frikipedia

The DLR is not a real Underground service as it rarely actually goes underground, it's more of a monorail-cum-rollercoaster (albeit a bit of a lame one).

It tours the Docklands area of London, including the Quarf.

Because tramps can't afford to beg in the Docklands, it achieves an ECUC of just 2%.

Any journey on the DLR should be welcomed by a chorus of MONORAIL!. Despite the fact that it isn't actually a monorail.

The DLR is the most efficient form of transport to get to Cyprus.
