Sunny Starscout and her friends have been on many challenging adventures, and believe they can tackle anything the world throws at them.

All of this changes when they discover the remains of an old railway line that used to connect Equestria together. Getting it restored would assist with bringing the country together, but the challenges are immense. Geography, resources, and various other problems work against them. Have the Mane 5 truly met their match?

A complete rewrite of my first ever story, Railway Adventure, and written to mark five years since I started writing My Little Pony fanfiction. Takes place after the events of Chapter 3 of Make your Mark, but was planned and written before Chapter 4 began airing, and as a result does not take it into account.
