Peter F. Hamilton&#x27;s <i>Commonwealth Saga</i> involves interstellar travel on trains[1] which pass through artificial wormholes. I wouldn&#x27;t recommend the books; he creates a world with so much potential, but the characters and story are disappointing.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Commonwealth_Saga#Technological_concepts" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Commonwealth_Saga#Technologica...</a>
