TubeCorp
From Tardis Wiki, the free Doctor Who reference
TubeCorp was an organization which had authority over trains in the London area in 2050.
In that year, Brook Thomas, head of TubeCorp, appeared on Channel 8 news to announce that all trains were running on time, even those which had left several hours late. Some, she said, were even arriving before they departed. This was actually a side-effect of the time distortions caused by the Oroborus. (K9TV: Oroborus)
Behind the scenes
It can be inferred from the name that TubeCorp is the result of a privatization of the London Underground.
