Overview
Train Logs are the endgame currency earned from Beyond the Rails: Prime Circle, the permanent ten-stage challenge tower that opens once the main story prologue is complete. Train Logs accumulate as players Perfect Clear stages of Prime Circle and refill on the mode's periodic reset cadence. They are spent in the Prime Circle exchange shop, where the rotating stock includes Mind Shards, Arc enhancement modules, and rotation-exclusive cosmetics.
Train Logs are the only currency in Neverness to Everness tied directly to a permanent endgame mode. Their cadence makes them a long-running progression track rather than a launch-window source: a player who clears Prime Circle perfectly each rotation accumulates Train Logs across the entire live-service lifetime of the game.
How to Earn Train Logs
Train Logs drop on Perfect Clears of Beyond the Rails: Prime Circle stages. Each of the ten stages pays a Train Logs bundle on Perfect Clear; partial clears (Standard Clear) pay reduced amounts. The full ten-stage perfect ladder hits the per-rotation cap on Train Logs.
Per-stage Perfect Clear: Train Logs bundle (variable, scales with stage number)
Full ladder Perfect Clear: per-rotation Train Logs cap
First-clear bonuses: one-time Train Logs payouts on the first time a stage is cleared. These do not refresh on rotation reset.
How to Spend Train Logs
The Prime Circle exchange shop's stock rotates with the mode itself. Confirmed spending categories include:
Mind Shards for limited and standard pool characters. The Prime Circle shop is one of the few non-gacha sources for Mind Shards on limited characters such as Nanally and Hotori. Mind Shards leave the shop for several rotations after a character's first headline appearance.
Arc enhancement modules for refining and enhancing weapon Arcs
Rotation-exclusive cosmetics: profile frames, name cards, and travel-themed accessories tied to each Prime Circle rotation theme
One-time bundles of upgrade currencies and ascension materials, refreshed on rotation reset
Reset Cadence
Prime Circle resets on a fixed cadence. At each reset, the Train Logs exchange shop's stock refreshes, the per-rotation reward chests refill, and stage clear states are wiped so players can re-clear the ten stages for a fresh round of Train Logs. First-clear bonuses do not re-issue, but standard reward bundles per Perfect Clear repeat indefinitely.
Tips
Spend Train Logs on Mind Shards first, cosmetics second. The shop refills on a cadence that lets you grab cosmetics on a later rotation; Mind Shards rotate in and out of stock based on the character spotlight, so missing them in one rotation can mean waiting several before they return.
Push for Perfect Clears on Stages 1 through 6 first. The early stages have manageable Perfect conditions; the late stages enforce strict damage windows that reward focused investment.
Stage clears persist within a rotation, so partial progress carries over. There is no penalty for spreading the ten stages across multiple sessions.
Train Logs are not interchangeable with any other currency. They are a closed-loop currency tied entirely to Prime Circle.
