I figured out what the problem was, and it wasnt' as a fandom user pointed out, not having the HyperLoop era bought. I wouldn't be asking why i cant call hyperloops if i did not have that bought already, kind of logical, no?

The problem seems to be that once you buy the Hyperloop Era (and i suspect that is true for all of the era extensions), you have to reload the game.

Just after i bought it, even if i filled my other rails with express trains, i would not get a hyperloop but the game would show me a coloured whistle that i could click on. After i reloaded the game, i could also call Hyperloops via Whistle
