What is "nightstar"

Nightstar is a fictional character from DC Comics, the daughter of Starfire or Koriand'r and Dick Grayson in an alternate universe, the latter of which was the first Robin and later Nightwing. Her superhero name is a play on those of her parents (Nightwing, Starfire) but her civilian identity is that of Mar'i Grayson.

The Nightstar was a proposed overnight sleeper service from various parts of United Kingdom to continental Europe, via the Channel Tunnel. To run alongside the Eurostar and north of London day-time Regional Eurostar services, the Nightstar was the last part in a round-the-clock passenger train utilisation of the Channel Tunnel.

After rejection of various British ideas for the service that was to become the British Rail Class 373 Eurostar train—which eventually was created from the existing French TGV scaled for a British loading gauge—the Nightstar concept emerged as an individual locomotive-hauled passenger train. While some carriages were built, the project was cancelled in 1997 for lack of commercial viability. Some of the stock was eventually sold to Canada, where it became Via Rail's Renaissance train fleet.
