On Track (The Old Store Lost Tales: 4‪)‬

Another standalone Lost Tale in the post-apocalyptic Old Store collection. After narrowly escaping the massacre suffered by Rat's biker gang, Calli seeks a route less likely to end in deadly pursuit. Still with a thirst for adventure, she joins a small party riding a train across the neglected landscape. They are not long out of the city when they realise that being stuck on a fixed track can be even more hazardous than being on the road.

Bonus story: 'Bad Water'. One of the characters from 'On Track' tells his own version of his thwarted attempt at stowing away on Calli's train, and how he then tried to redeem himself in the eyes of the other townsfolk.

There are quite a few differences between UK and US rail terms, so a glossary is provided near the end of the book.
