The first passenger train to the diamond in Whitefield in 25 years gets the highball with 252 on the point.

The Wiki page for highball (the train thing) - redirects to the page for express train. And there's an illustration of a highball.

Highball - Wikipedia

A highball is a mixed alcoholic drink composed of an alcoholic base spirit and a larger proportion of a non-alcoholic mixer, often a carbonated beverage.

Etymology

The name may have come from early railroad signals with raised globes meaning "clear track ahead", i.e., "you're good to go".

Highball can be a verb meaning travel fast. But that usage seems obscure to me. I don't think I've ever heard it.
