Re: Train Station?
It occurs to me that ElReg needs a couple of units of length that are slightly longer than a London bus or a brontosaurus.
May I suggest a pair of units, the Bars (at 3.4km, 155ish Brontosauruses) and the Hadrian (at 117.5km, or 839285.7143 Linguini (obviously)).
For a unit of negative measurement, perhaps the Trump (93 miles (150 km, or 2338 Devon fatbergs) of unnecessary replacement, no actual new wall to date) would be appropriate.
 Not bar, Bars. See: York. And have a homebrew while you think about it, not that that has anything to do with it ... but it can't hurt.
